At the conclusion of a two-day trial, a jury convicted appellant, Gerald McKinnon, of first-degree burglary while armed, 1 assault with intent to kill while armed, 2 mayhem while armed, 3 and carrying a dangerous weapon. 4 Subsequent to sentencing, appel-' lant filed a timely direct appeal, arguing principally that the evidence was insufficient to sustain the burglary and mayhem convictions. He later made a collateral attack on his convictions as well, filing a motion for new trial pursuant to D.C.Code § 23-110 (1989 Repl.), in which he asserted ineffective assistance of counsel. The trial court denied the § 23-110 motion. 5 We consolidated appellant’s appeal from denial of the motion with his direct appeal. We find no merit in either appeal, and therefore affirm.
I.
Evidence produced at trial showed that appellant arrived unexpectedly at the apartment of his former girlfriend, complainant Denise Smith, the morning of August 19, 1990. Although Smith was “shocked” to see him, she admitted him to her apartment. Smith’s friend, Blanche Farrish, was inside Smith’s apartment at the time, but Farrish left shortly after appellant’s arrival to locate a telephone in order to make some calls. After appellant and Smith had conversed for a short while, Smith stated that she was going to leave to meet Farrish outside. Appellant and Smith then left the apartment together.
Upon exiting the apartment building, appellant stated that he had left his cigarettes inside Smith’s apartment. Refusing her offer to buy him a new pack, he insisted that she return to her apartment to retrieve them. He then followed her as she ascended the stairs to her apartment, entered the apartment with her, and immediately locked the door behind them.
Appellant then attempted to initiate a conversation about the couple’s relationship. Smith was unreceptive. After a period of argument, the length of which was not clearly established at trial, appellant stated that neither of them had anything to live for. He drew out a ten to twelve inch butcher knife that he had concealed in his clothing and began to cut and stab Smith.
Farrish, who was standing outside the apartment building, heard Smith scream. Farrish attempted to gain entry to Smith’s apartment but, because appellant had locked the door, could not. While the attack continued, Smith made her way to a window of her third-floor apartment and jumped out. This attempt to evade appellant was at first unsuccessful, as he jumped out after her, knife in hand.
A neighbor who heard the argument called the police and, while doing so, saw Smith and appellant land on the ground beneath her window and saw appellant’s bloody knife. She shouted at appellant. At that point appellant abandoned the attack, wiped off the knife, and departed on foot.
In his defense, appellant presented two alibi witnesses who testified that he was elsewhere on the morning of the assault. The jury convicted appellant of the four offenses listed above.
II.
On direct appeal appellant asserts: (1) the evidence was insufficient to establish *441 the “intent” element necessary to sustain the burglary conviction; (2) the evidence was insufficient to establish the “permanent injury 5 ’ element necessary to sustain the mayhem conviction; (3) the court committed plain error in failing to give a unanimity instruction; and (4) the jury possibly convicted him on an improper theory (a variation of the unanimity argument, as the allegedly improper prosecution theory is essentially that the first entry constituted a burglary). Only the first two of these four arguments warrant extended discussion here. 6
The Burglary Conviction
Appellant argues that the trial court committed reversible error when it denied his motion for judgment of acquittal on the basis of insufficiency of the evidence of the “intent” element of the burglary charge. The elements of burglary in the first degree are: (1) the entering of a dwelling, or room of another used as a sleeping apartment, while it is occupied by any person; (2) with intent to commit a criminal offense. See D.C.Code § 22-1801(a) (1989 Repl.); CRIMINAL JURY INSTRUCTIONS FOR THE DISTRICT OF Columbia, No. 4.34 (4th ed. 1993). Appellant contends that on the basis of the evidence presented at trial, no reasonable juror could be convinced beyond a reasonable doubt that at the time he entered Smith’s apartment he had the intent to commit assault.
In ruling on a motion for judgment of acquittal alleging insufficiency of evidence, the trial court must review the evidence in the light most favorable to the government.
Curry v. United States,
In
Johnson v. United States,
We note that
Johnson
and
Warrick,
*442
like many of our precedents,
7
involved entries that were plainly unauthorized. In this case, Smith acquiesced in the entry during which she was assaulted, but her acquiescence was obtained by ruse,
ie.,
appellant’s insistence that they reenter Smith’s apartment so that he could recover his pack of cigarettes. In our view, this arguable distinction has no bearing on the manner in which the finder of fact should determine intent. This would be so even if there had been an untainted consent to enter. It is well-established that “consent to enter is not a defense [to burglary] where one is shown to have entered with the requisite criminal intent.”
United States v. Kearney,
In this case, the trial court identified three other circumstances that support the inference that appellant possessed the intent to assault Smith when he entered her apartment for the second time. First, appellant locked the door behind him. Second, he carried a large butcher knife hidden in his clothing. Third, there was “no prolonged discussion” after the second entry and prior to the attack. We add that appellant’s use of a ruse or strategy to lure his victim back into her apartment is also a circumstance supporting a finding of intent.
Appellant attempts to ward off the inference of intent with factual and legal arguments.
8
Two of his legal contentions warrant our attention. First, relying on this court’s decision in
Warrick,
appellant argues that possession of a weapon cannot furnish the basis for the inference that he possessed the intent to assault Smith at the time he entered her apartment the second time.
See Warrick, swpra
note 7,
Appellant argues that his intent to assault was similarly conditioned upon the unpredictable flow of events subsequent to his entering Smith’s apartment. This attempt to place himself within the Warrick framework fails. The crucial distinction is that here appellant entered Smith’s house while armed for the purpose of having a confrontation with her. It is reasonably inferable from his words to Smith when he drew the knife that in the event Smith did not comply with his wishes he intended to kill her. Entering an occupied dwelling with such an intent is within the range of evils the burglary statute was intended to prevent. 9
*443 Second, appellant challenges the evidentia-ry basis for the trial court’s statement that there was no “prolonged discussion” prior to the attack. (This was ■ one of the circumstances the trial court cited in denying appellant’s motion for judgment of acquittal.) Although there is evidence that the assault was preceded by at least some conversation between appellant and Smith, it is not possible to determine precisely from the trial testimony the amount of time that passed from appellant’s second entry into the apartment until the physical assault. While there was evidence presented at trial which could be construed to support the trial court’s conclusion, 10 we need not decide whether that evidence supports the trial court’s finding regarding the time that passed between entry and assault in order to uphold the court’s view that there was sufficient evidence of intent. We hold that three “other” circumstances — the use of a ruse to coax Smith back to her apartment, locking the apartment door, and carrying a concealed weapon — provide more than sufficient basis for such an inference.
The Mayhem Conviction and Denial of the § 23-110 Motion
Appellant makes two contentions with regard to his conviction for mayhem. First, on his direct appeal he argues that the trial court erred in denying his motion for judgment of acquittal on the mayhem conviction. In that motion he asserted that the government failed to prove the “permanent injury” element of mayhem. In its brief on direct appeal, the government responded that due to McKinnon’s trial counsel’s statement before closing argument that he would not contest the government’s claim that the removal of sixteen inches of Smith’s small intestine constituted permanent injury, appellant could not pursue this issue on appeal. Appellant thereupon filed a motion for new trial pursuant to D.C.Code § 23-110 (1989 Repl.), arguing that trial counsel afforded ineffective assistance of counsel when he made that agreement. The denial of that motion is on appeal here.
We agree with the government that the defense conceded at trial the issue whether the injury to Smith’s intestines satisfied the permanent injury element of mayhem, and therefore cannot pursue that point on direct appeal here.
See Byrd v. United States,
Appellant correctly asserts that permanent disabling injury is an element of mayhem.
Edwards v. United States,
Appellant’s basic defense at trial was alibi. His counsel’s failure to argue that Smith’s injury was not permanently disabling was inconsequential to the success or failure of that defense. We make this observation not to decide the prejudice prong of the
Strickland
test, but to state the basis for considering whether trial counsel’s decision to concede the permanent injury element of mayhem can fairly be viewed as tactical. In that regard, the trial judge concluded that “defense counsel’s tactical decision to circumvent questioning on gruesome injuries sustained from the stabbing in order to focus the juries’ [sic] attention on the defense alibi theory was a logical decision....” Under the circumstances of this case, we defer to the trial judge’s finding that the alibi defense could well have been undermined by protracted and probably gory testimony as to whether Smith’s abdominal stab wounds (which were described as life-threatening by her treating physician) resulted in permanent disability. Accordingly, we will not disturb his conclusion that defense counsel’s decision ' was tactical. Because “[t]actical decisions which may go awry at trial do not constitute ineffectiveness,”
Carter v. United States,
Accordingly, appellant’s convictions and the trial court’s denial of his § 23-110 motion are
Affirmed.

.In denying the motion, the trial court noted that appellant had not requested a hearing and that appellant’s counsel had "telephonically communicated to the court that he believed a hearing would not be necessary.”
. We need not address appellant’s latter two arguments at length. As to unanimity, the government elicited testimony from its witnesses, and referred in argument to two separate occasions upon which appellant entered complainant's apartment on the morning of the assault. On this basis, appellant asserts that the trial court committed plain error in its failure
sua sponte
to give a unanimity instruction to the jury on the burglary while armed charge. Because appellant did not request the instruction at trial, we review this claim under the plain error standard.
Watts v. United States,
For the same reason, we find no merit in appellant’s argument that the jury may have convicted him on an improper theory. Appellant also argues on direct appeal that the trial court committed plain error in giving without objection an "acquittal first” instruction in its initial charge to the jury. We find no plain error.
See Jones v. United States,
.
See, e.g., Shelton v. United States,
. Regarding factual matters, for example, he states that it was reasonable to lock the door given the rough character of the apartment complex. It was for the jury to weigh such facts.
.The Model Penal Code states that “[w]hen a particular purpose is an element of an offense, the element is established although such purpose is conditional, unless the condition negatives the *443 harm or evil sought to be prevented by the law defining the offense.” Model Penal Code § 2.02(6) (Proposed Official Draft 1962). (An example of a condition which negatives the presence of such an evil would be the taking of property in the possession of another, with the intent of returning it if it is found not to be the property of the person who took it. 1 Wayne R. LaFave & A. Scott, Substantive Criminal Law, § 3.5(d) (1986)).
. The close proximity in time between an attacker's entry into a premises and a subsequent assault was cited by the
Johnson
court as one factor supporting an inference of the defendant’s intent upon entry.
Johnson, supra
note 7,
To controvert the trial court's conclusion that there was no prolonged discussion prior to the attack in the instant case, appellant cites Smith’s testimony that appellant had been in her apartment "about an hour” prior to the attack, as the "only estimate of time given by any witness.” But appellant ignores the testimony of Smith's friend, Farrish, who was outside the building waiting for Smith at the time of the attack. She testified that when appellant and Smith returned to Smith’s apartment to retrieve appellant's cigarettes, it was only a “short period” before she heard Smith begin to scream. It was within the province of the juiy to credit Farrish's estimate of the amount of time that elapsed instead of Smith’s.
. We distinguish our holding in
Gillis v. United States,
. Specifically, we need not determine whether the evidence was sufficient to establish that the removal of a sixteen-inch portion of the complaining witness' small intestine was a permanent injury that substantially impaired the normal functioning of her body. In that regard, we note that in
