Kaplan, J.
In April, 1976, a Suffolk County jury found the defendant Gregory Robinson guilty of murder in the first degree, of armed robbery, and of two counts of assault by means of a dangerous weapon.
Shortly after sentence, counsel filed a formal motion for a new trial and a notice of appeal. The trial judge denied the motion in July, 1977, and dismissed the appeal in December, 1977, for failure to file an assignment of errors (see G. L. c. 278, § 33F, repealed by St. 1979, c. 346, § 3). The defendant, however, acting'pro se, in January, 1978-, filed a second motion for a new trial. Appointed counsel improved the motion by amendment. It was denied by the trial judge in November, 1979, with memorandum dated in April, 1980. This denial is the subject of the present appeal.
The motion contended that the prosecutor’s use of peremptory challenges in jury selection was racially biased, and also attacked several parts of the judge’s charge to the jury: his instructions on the jury’s role in determining the degree of murder, on premeditated murder, on reasonable doubt, and on the burden of proof (in general, and as to “duress”). After describing the facts, we consider these points, and conclude by affirming the convictions.
1.
Narrative.
We state briefly the core facts. The defendant and one Ronald Ellis
approached the Peking House
restaurant in the Roxbury section of Boston about 12:45 a.m., December 16, 1975, and asked Shung Li, who was locking the front door, for an order of rice.. Shung Li allowed the men to enter and walked with them to the rear kitchen area of the restaurant where Yip Ming, Yung Kam Tai, and Sheung Lee were cleaning up. Ellis drew a sawed-off shotgun from under his jacket and ordered the four employees to get down on the floor. He told the defendant to search for money. Although Sheung Lee quickly rendered Ellis’s order to the employees into Chinese, Shung Li, who had little English, may have remained standing. Ellis fired his shotgun, wounding Shung Li in the chest. Ellis and the defendant left the restaurant with some $300 the defendant had found in a kitchen cabinet drawer. Shung Li died of the wound next day.
We turn to the defendant’s testimony about the events of the evening in which he sought to picture himself as acting under supervening pressure from Ellis. The defendant said he met Ellis for the first time at a “shooting gallery” in Roxbury between 8 and 9 p.m., December 15. Ellis had taken cocaine or heroin; the defendant took heroin. While waiting for the shots to take effect, Ellis spoke of an encounter with an acquaintance at a bar earlier that evening which had ended with the man pulling a pistol on him. He solicited the defendant’s help in fetching his own gun and going back to the bar to confront the man. The defendant undertook to drive Ellis to Ellis’s house in Dorchester and they drove off in the defendant’s automobile, a green Buick borrowed, as it happened, from the defendant’s girl friend Janice Bacon.
Arriving at Ellis’s house, the defendant waited in the car while Ellis went in and then emerged with a green Army duffel bag containing, as the defendant assumed, a gun (in fact a sawed-off shotgun). The defendant drove to the indicated bar near the Dudley subway station in the Roxbury
section of Boston and again waited as Ellis entered and returned, saying that the man was not there.
The defendant and Ellis drove about for two hours talking and drinking wine. Ellis spoke of “taking off some joint” but the defendant, so he testified, disclaimed any interest in such a venture. Finally they returned to Roxbury. Coming out of a bar where they had used the rest room, Ellis proposed robbing a Merit gas station across the street. The defendant declined to take part, and drove off alone. But as the defendant waited a red light at a near corner, Ellis reentered the car taking the front passenger seat. At that point Ellis’s shotgun discharged into the adjacent door. The blast, said the defendant, “panicked” him. Ellis said it was an accident, but the defendant testified he “couldn’t understand” how that could be.
The defendant asked Ellis where he wanted to be left off and Ellis directed him, but en route Ellis ordered the defendant to stop by the Peking House restaurant so they could rob it. The defendant said he didn’t want to do it and pointed out some hazards in the robbery as a means of discouraging Ellis. But ultimately he did as Ellis wished because he was “afraid” of Ellis and his shotgun and “couldn’t see anything else to do.”
As to his conduct while in the restaurant, the defendant testified that he alternated between acting as lookout from a position in the doorway between the kitchen and the front serving area, and responding to Ellis’s command to search for money by rummaging in a kitchen cabinet. At one point he blocked Ellis from pushing one of the employees into the serving area; he explained that he feared the police would see the robbery in progress and shoot him as they entered. He said he tried to persuade Ellis to leave the restaurant, but Ellis merely directed him to look for more money. Regarding the shooting of Shung Li, the defendant testified he was on lookout when he heard the shot. He ran to the store front to see if anything stirred, and returned to the kitchen area. He did not notice that Shung Li had been wounded. On Ellis’s order he resumed looking for money in the kitchen
cabinet. Some minutes later, when Sheung Lee reached across him for the phone to call a doctor, he turned and saw Shung Li bleeding on the floor. He and Ellis then left.
There was possible confirmation of part of the defendant’s story in the testimony of Janice Bacon, called by the defense. She said she found a hole in the front passenger door of her Buick automobile that was not there, she thought, when she lent the car to the defendant on December 15. But she said she first observed the hole sometime in January. James E. Higgins, a Boston police ballistician, called by the prosecution, testified that the hole in the door was consistent with a blast from a shotgun, but that it could also have been made by ramming an iron rod through the door.
Without getting into the detail of the Commonwealth’s case, we say a word about its evidence bearing on the claim of duress. Ellis was not called. The defendant’s taped statement, given to Detective Peter O’Malley on January 8, 1976, was played to the jury. Here the defendant indicates that the robbery was Ellis’s idea, but there is not more than a hint of duress. On the tape the defendant says that he and Ellis were broke that night and were driving about looking for a “place to hit.” The tape has nothing about a shotgun blast in the car. (In testimony the defendant said he was “confused” the day he talked to Detective O’Malley, and O’Malley had cut off his statement at various points. Neither claim is evident from hearing the tape. It appears to run continuously during the defendant’s statement.) On the tape the defendant says that after stopping the car two doors down from the restaurant in front of a smoke shop, he moved the car some distance to avoid bright illumination of the license plate by the shop’s neon lights. (In testimony the defendant explained the move as intended to allow the customers to leave the restaurant and the door to be closed so that the robbery would be thwarted.)
Donna Horner, a prosecution witness, said the defendant told her that he and another fellow had robbed a Chinese restaurant; that as they were leaving the place he told the
other guy to “[sjhoot the motherf-----” and to his surprise the fellow did shoot. He also told her that he carried a pistol during the episode, and the other fellow a shotgun. The defendant’s avowal to Horner came on January 2, 1976; she said they were in bed together, the defendant (but not Horner) having taken heroin.
(It may be noted that the restaurant employees did not observe a weapon in the defendant’s hands.)
After the robbery, the defendant accompanied Ellis to Ellis’s girl friend’s place. As against testimony by the defendant suggesting that he continued in fear of Ellis, the girl friend, Diana Dozier, called by the Commonwealth in rebuttal, described the two as counting out and dividing the money and saying they could have gotten more, and mentioning an “accidental” shotgun burst in the car in what she took to be a friendly or joking manner. She said the defendant came by two days later asking for Ellis. He asked for Ellis again when she ran into him at Dudley station three days after the robbery.
With respect to chances of escape, the defendant said on the tape that he was alone in the car when he moved it down from the smoke shop. (He put Ellis still in the car in his testimony.) In testimony the defendant admitted that Ellis stopped to put on the defendant’s coat before the two entered the restaurant (the shotgun could be concealed under the coat), but he claimed nevertheless that the shotgun never left Ellis’s possession. He knew a bar across the street from the parked car which he “imaginefdj” would be open late, but he did not try to run to it. Just after Shung Li was shot he was alone at the store front, but did not try to leave because, he said, he was not sure the door would open.
2.
Peremptory challenges.
The defendant is black. He argues that the prosecution denied him rights under art. 12
of the Declaration of Rights of the Massachusetts Constitution, as laid out in our opinion in
Commonwealth
v.
Soares,
377 Mass. 461, 488, cert. denied, 444 U.S. 881 (1979), by using peremptory challenges to exclude “all persons of color” from the jury that tried him. The jury were all white. Objection was taken the day after empanelment and made the basis of a motion to empanel a new jury, which the judge denied. As to the circumstances of jury selection, we have only the statement of the defense attorney as he recorded his objection: the prospective jurors examined included three blacks and one Puerto Rican; one of the blacks was excluded for cause, the other three were challenged peremptorily by the prosecutor.
Soares
applies retroactively to defendants in cases “pending on direct appeal [at the time of decision, March 8,1979] where the record is adequate to raise the issue.”
Id.
at 493 n. 38. But the appeal of the present defendant had been dismissed a year earlier, on December 1, 1977. In
Reddick
v.
Commonwealth,
381 Mass. 398, 399 (1980), we reasserted the limit on retroactive application at least where, as here, racial tension appeared not to have been a factor at trial. The present record would be a poor candidate to command a reversal of the convictions under
Soares
in any event.
According to
Soares
a presumption continues that peremptory challenges were properly used, which can be overcome on a showing sufficient to support the inference that the challenges were so exercised as to exclude individuals on the basis of their group affiliation.
Id.
at 490. Factors in the assessment include not only the numbers and percentage of group members excluded, but also common group membership of the defendant and the jurors excluded, and of the victim and the remaining jurors.
Id.
Compare the figures given above with those in
Soares:
twelve of thirteen blacks were excluded there. While the defendant here was black
as were three of the four excluded jurors, the victim of the crime was Oriental and none of the final jury was such. We doubt that a trial judge on this showing would have had a basis for finding that the peremptory challenges were used improperly. We would sustain a finding that the presumption of proper use was not rebutted. See
Commonwealth
v.
Walker,
379 Mass. 297, 300-301 (1979).
3.
Jury’s role as to the degree of murder.
The trial judge instructed on two kinds of murder in the first degree, felony-murder and premeditated murder, and charged further that “[mjurder which does not appear to be murder in the first degree is murder in the second degree.” He omitted, however, to read the jury the last sentence of the murder statute, G. L. c. 265, § 1: “The degree of murder shall be found by the jury.”
In
Commonwealth
v.
Dickerson,
372 Mass. 783 (1977), we held that it was proper for the judge in a case with facts like those at bar to submit the question of murder in the second degree to the jury, and to inform them of their authority under the statute to find the degree of murder. This was held correct even where arguably the facts would support only a finding of murder in the first degree, for the jury “within their power to appraise evidence selectively, might have accepted as credible enough evidence to establish a conviction of murder in the second degree, but might have declined to accept such further evidence as tended to prove a case of murder in the first degree.”
Id.
at 795-796 (footnote omitted). We went on to outline a proper charge on murder and the degree of murder which comprised a reading of the murder statute, including the last sentence.
Id.
at 797-798 n.6.
In the present case counsel for the defendant excepted to the failure to charge on manslaughter, and on larceny in relation to the armed robbery charge (exceptions not argued
on this appeal). There was no objection or exception to the judge’s omission to refer in terms to the jury’s power to find murder in the second degree. We held in
Commonwealth
v.
Hooks,
375 Mass. 284, 290-292 (1978), that an inadequate instruction on murder in the second degree did not amount to reversible error when counsel failed to alert the judge by exception and when a finding of murder in the second degree would fail of support in the facts.
Hooks
foreshadows the result here. The defendant admitted participation in an armed robbery resulting in a homicide. His sole ground for possible acquittal was duress. Nothing in the facts looked to murder in the second degree. Compare
Commonwealth
v.
Rego,
360 Mass. 385, 396-397 (1971). We may reverse for error that raises “a substantial risk of a miscarriage of justice” in the absence of exception
(Commonwealth
v.
Freeman,
352 Mass. 556, 564 [1967]), but we think there is no such risk here stemming from the failure to charge in full under the statute.
4.
Instruction on premeditation.
Here is another claimed error not objected or excepted to. The contention now made is that the facts, while supporting a coventured felony-murder, would not support premeditated murder, and so giving a charge on premeditation was error.
If the absence of exception is forgiven, there was still no error. Donna Horner’s testimony, that the defendant confessed to her that he directed Ellis to shoot Shung Li, was sufficient to warrant an instruction on premeditation. We need not speculate whether the jury might take a view of the evidence, even apart from Horner, that could associate the defendant with Ellis’s premeditated murder of Shung Li on a theory of joint enterprise or coventure. See
Commonwealth
v.
Richards,
363 Mass. 299, 308-309 (1973).
5.
Reasonable doubt.
The defendant contends for the first time that the charge on reasonable doubt (the essence
of which is set out in the margin
) was “momentary, fragmented and scanty.” We think it was adequate. It stated that being satisfied beyond a reasonable doubt means having a “full and abiding conviction of the guilt of the defendant” after a “careful and candid and impartial consideration of all the evidence.” This conformed to
Commonwealth
v.
Webster,
5 Cush. 295, 320 (1850), which we cited recently as the best source for “unimpeachable” instructions on reasonable doubt. See
Commonwealth
v.
Ferreira,
373 Mass. 116, 130 n.12 (1977). The remark in the judge’s instruction about “doubt based on reason” is subject to the criticism made in
Commonwealth
v.
Bjorkman,
364 Mass. 297, 308 (1973), and in
Commonwealth
v.
Hughes,
380 Mass. 596, 598-602 (1980), but in both cases we thought that lapse itself should not be held fatal.
The same holds here when the charge is read as a whole. See
Commonwealth
v.
Garcia,
379 Mass. 422, 441 n.12 (1980);
Commonwealth
v.
Kelley,
359 Mass. 77, 92 (1971).
6.
Burden of proof in general, and as to duress.
The claim freshly made here, that the charge failed to place the general burden of proof clearly on the Commonwealth, is quite unsupported. At two points in the instructions the jury were told that the Commonwealth must prove beyond
a reasonable doubt all essential elements of the crimes charged. This burden was further explained in connection with the presumption of innocence, and the point was also driven home by a contrast between the Commonwealth’s burden in a criminal trial and the preponderance burden borne by a party in a civil matter. Although some isolated comments in the charge on the defendant’s privilege to remain silent and on the role of defense counsel could not be thought ideal, they did not shift any burden to the defendant or undercut the statements placing the general burden firmly on the Commonwealth.
We turn to the defendant’s more serious contention, again not made the subject of an exception, that the instructions erroneously placed on him a burden of proof as to duress. As to the meaning of duress, the early case of
Commonwealth
v.
Elwell,
2 Met. 190, 192 (1840), said merely that no “criminal will or purpose” could be implied from an act that was caused “by force or the compulsion of others.” The theme has not been renewed in our modern cases,
and so we need say here that, in respect to serious crimes of the order involved in the present case,
“duress” is usually taken to require a present, immediate, and impending threat of such a nature as to induce a well-founded fear of death or of serious bodily injury if the criminal act is not done; the actor must have been so positioned as to have had no reasonable chance of escape. See
R.I. Recreation Center, Inc.
v.
Aetna Cas.
&
Sur. Co.,
177 F.2d 603, 605
(1st Cir. 1949);
Shannon
v.
United States,
76 F.2d 490, 493 (10th Cir. 1935). See also Annot., Coercion, Compulsion, or Duress as a Defense to Criminal Prosecution, 40 A.L.R.2d 908, 910-911 (1955). He must have been put in a condition of mind where neither he nor a person of reasonable firmness could have acted otherwise in the circumstances.
United States
v.
Haskell,
26 F. Cas. 207, 210 (C.C. E.D. Pa. 1823) (No. 15,321);
Powe v. State,
176 Miss. 455, 461 (1936). See also Model Penal Code § 2.09(1) (Proposed Official Draft 1962).
The trial judge’s instructions were essentially faithful to this description of duress and no serious challenge on that score is made now.
The parties assumed, as did the trial judge in his memorandum, that in the state of the record the judge was obliged to instruct the jury on duress. That was correct, for “ [t]he fact that the evidence may not be of a character to inspire belief does not authorize the refusal of an instruction based thereon.”
Commonwealth
v.
Campbell,
352 Mass. 387, 398 (1967), quoting from
People
v.
Carmen,
36 Cal. 2d 768, 773 (1951). Also assumed were two more controversial points — that the defendant was entitled to an instruction on duress with respect to murder as well as the other crimes charged,
and that, under
Mullaney
v.
Wilbur, 421
U.S.
684 (1975), the Commonwealth bore the burden of negating duress beyond a reasonable doubt as a matter of due process. Thus it is from the viewpoint of our self-defense cases implementing
Mullaney,
for example,
Commonwealth
v.
Rodriguez,
370 Mass. 684 (1976), and
Commonwealth
v.
Stokes,
374 Mass. 583 (1978), that the parties and the trial judge have discussed the adequacy of the charge in casting the burden regarding duress, and the effect of a failure to take exception.
As to the first assumption, the common law doctrine was that murder (in some undifferentiated sense) remained punishable as such regardless of duress (see R. Perkins, Criminal Law 951 [1969]; Annot.,
supra
at 909
), a posi
tion still taken in many
but not all
States that speak to the point by statute. The second assumption is troublesome because the standards applied in the cases following
Mullaney
are influenced by the fact that constitutional imperatives are conceived to be involved. Thus
Stokes, supra
at 591, defined a “constitutionally sufficient” instruction on burden of proof, and the decision there to review such instructions
despite the absence of exceptions in trials predating
Rodriguez
derived in part from the decision in
Hankerson
v.
North Carolina,
432 U.S. 233, 241, 243 (1977), to give the constitutional right announced in
Mullaney
a retroactive effect. See
Stokes, supra
at 588-590. But perhaps duress should not fall into the same constitutional pattern as self-defense or comparable matters.
Due process requires that the State disprove beyond a reasonable doubt those “defenses” that negate essential elements of the crime charged. See
Patterson
v.
New York,
432 U.S. 197, 210 (1977);
State
v.
Arpin,
R.I. (1980) (410 A.2d 1340, 1350 [R.I. 1980]). See also
Mullaney, supra
at 705-706 (Rehnquist, J., concurring). This is a somewhat question-begging yet indicative canon. The defenses of provocation, self-defense, defense of others, a claim of “accident” — all are considered to go to the presence of “malice”; hence the State assumes the burden of disproof of each of them, where malice is an ingredient of the crime. See
Commonwealth
v.
Greene,
372 Mass. 517, 518-519 (1977) (provocation);
Connolly
v.
Commonwealth,
377 Mass. 527, 529-530 (1979) (self-defense);
Commonwealth
v.
Monico,
373 Mass. 298, 304 (1977) (defense of others);
Lannon
v.
Commonwealth,
379 Mass. 786, 790 (1980) (accident). Conceivably, however, duress is to be classified with insanity, the proof of which may, according to the Supreme Court, be fastened on the defendant without due process difficulties. See
Rivera
v.
Delaware,
429 U.S. 877 (1978) (dismissing for want of a substantial Federal question a Delaware decision placing the burden as to insanity on the defendant);
Leland
v.
Oregon,
343 U.S. 790, 799 (1952). See also
Mullaney, supra
at 705-706 (Rehnquist, J., concurring).
Yet if the effect of duress, as defined, is to reduce the person to a state of involuntariness or automatism, see Model Penal Code § 2.09, Comment at 6
(Tent. Draft No. 10, 1960), then duress may be seen as removing the very basis of criminal culpability, see Model Penal Code § 2.01(2) (d) (Proposed Official Draft 1962), with due process implications as regards burden of proof. See also
Sandstrom
v.
Montana,
442 U.S. 510, 514-515 (1979) (due process requires that State bear the burden on “intent”).
In fact, a number of recent decisions, cited in the margin,
that place the burden regarding duress on the State, have done so on grounds derived from statute or other reasoning, and not because of supposed constitutional compulsion. One decision has put the burden on the defendant without adverting to any constitutional problem.
State
v.
Toscano,
74 N.J. 421, 443 (1977).
Two other decisions
have reached the same result after dismissing constitutional objections, relying on
Patterson
v.
New York, supra.
See
Foraker
v.
State,
394 A.2d 208, 214 (Del. 1978) (relying on
Goddard
v.
State,
382 A.2d 238, 241 [Del. 1977], denial of writ of habeas corpus affd sub nom.
United States ex rel. Goddard
v.
Vaughn,
614 F.2d 929 [3d Cir. 1980], which in turn relied on
Patterson); People
v.
Bevilacqua,
56 App. Div. 2d 605, 606 (N.Y. 1977), rev’d on other grounds, 45 N.Y.2d 508 (1978). The
Patterson
case is read as leaving a neutral space of unsettled dimension in which a State’s classification of a “defense,” with burden-of-proof consequences, will be respected by the Supreme Court and held beyond constitutional impeachment.
Our assignment of the burden of proof to the State with respect to insanity
(Commonwealth
v.
Kostka,
370 Mass. 516, 531-532 [1976]), alibi
(Commonwealth
v.
Leaster,
362 Mass. 407, 416-417 [1972]), and entrapment
(Commonwealth
v.
Miller,
361 Mass. 644, 651-652 [1972]) — all without reliance on the Constitution — suggests that we might do the same with duress. But this does not mean that we would scrutinize a charge as rigorously, or waive the failure to take exception to the charge as readily, as we have done in our self-defense decisions where the Constitution was in the foreground.
For purposes of the present case we are content to assume, without deciding, that duress was available to meet a charge of homicide,
and that the burden of disproving duress beyond a reasonable doubt was upon the Commonwealth as a matter of constitutional law (as that impinged on a trial in the
post-Mullaney, pre-Rodriguez
era).
Thus we grant the defendant, but only arguendo, the best of legal climates. On that basis we find that the instructions on the duress-burden were adequate.
There was no explicit instruction that the Commonwealth bore the burden of negating duress beyond a reasonable doubt. But
Stokes, supra
at 591, indicated, in the con
text of self-defense, that a charge could be constitutionally sufficient if it “clearly placed the burden of proving malice beyond a reasonable doubt on the Commonwealth and contained other discussion which, although not referring to the burden of proof as to self-defense and reasonable provocation, adequately defined those factors and established them as negating a finding of malice.” These words in
Stokes
followed from the indication in
Rodriguez
that the “critical” part of a constitutionally sufficient charge was that a “nexus” be established between the elements of the crime charged, and the absence of the particular defense. See
Rodriguez, supra
at 691;
Connolly
v.
Commonwealth, supra
at 529-530, 531. The instructions in the present case required the Commonwealth to prove voluntariness: the Commonwealth must, according to the charge, shoulder the burden as to all essential elements of the crimes charged, and criminal intent (which subsumes voluntariness, an absence of duress, see
People
v.
Tewksbury,
15 Cal. 3d 953, 964 n.9, cert, denied, 429 U.S. 805 [1976]) was such an element. The charge made the “critical nexus” in the following passage: “Perhaps I should say this: that the exercise of free will is essential to the commission of a criminal act. Criminality does not attach to an act committed under duress, if the actor had no free will, because if he had no free will he could have no criminal intent.” The charge here is rather like the one found adequate in
Gagne
v.
Commonwealth,
375 Mass. 417 (1978).
Gagne
followed
Stokes
in upholding a charge in which the judge did not instruct in terms that the burden of disproving provocation was on the . Commonwealth, but rather instructed that the Commonwealth must prove every essential element of the crime charged, that malice was an essential element, and that a legal justification or excuse, such as provocation, negated malice.
Id.
at 421. See also
Commonwealth
v.
Peters,
372 Mass. 319, 319-325 (1977) (charge sufficient which makes malice and provocation “mutually exclusive”).
There were remarks in the charge which, independently considered, might imply some burden on the defendant. We
comment on these although the defendant does not single them out for attack in his argument on this appeal. They included statements that the jury must “determine whether in this case there was . . . coercion or duress,” and that “the defense is not available” to a person in certain circumstances. Similar language in other cases has been deplored.
Rodriguez, supra
at 690, criticized a statement that the jury must “determine whether or not” the defense of self-defense existed;
Commonwealth
v.
Harrington,
379 Mass. 446, 453-454 (1980), saw difficulties with language that “[sjelfdefense is available to a defendant only under [certain] circumstances,” and is never “available” to an agressor.
But the charge held insufficient in
Rodriguez
contained additional, more troublesome language about the jury “find[ing]” or being “satisfied” that the evidence supported self-defense, see
Rodriguez, supra
at 690. See also
Connolly
v.
Commonwealth, supra
at 533-535 (reversing for charge repeatedly using “finding” language);
Commonwealth
v.
Collins,
374 Mass. 596, 600 (1978) (holding insufficient instructions that defendant “seeks to establish” self-defense);
Commonwealth
v.
Stokes, supra
at 592 n.5 (reversing for charge asking whether evidence was “enough to justify” provocation). And the charge in
Harrington
was held inadequate not only because of its language above quoted, but also because it failed to make the “critical nexus”: it “failed to define self-defense adequately or to explain its significance with reference to the question of malice.”
Harrington, supra
453-454. The charge at bar shares neither of these characteristics. We think any questionable remarks were overcome by the charge as a whole which was sufficient to inform the jury about their true duty. See
Commonwealth
v.
Bowden,

Section 33E considerations.
We have chosen to assume the obligation of examining this record as upon review under G. L. c. 278, § 33E, although the defendant does not assert that he is entitled to such review. (Some claim to § 33E treatment could perhaps be made on the ground that the appeal was not completed and this is the first opportunity to apply the statute. See
Commonwealth
v.
Smith,
381 Mass. 141, 146-147 [1980].) On this basis we find no reason to order a new trial or reduce the verdict. The jury could well find that the entire plea of duress was a fictional contrivance by the defendant and that it was disproved by the Commonwealth beyond a reasonable doubt. What is left is a murder and other crimes in which the defendant joined from beginning to end, from assistance in procuring the weapon to the flight from the restaurant with the avails in his pocket.
Order denying motion for a new trial affirmed.
