Generally speaking no. If the target is there and you can get close enough to whack it there's no luck in that. Fortuitous maybe, clumsy on the part of the opponent for allowing you to get close, drop his guard, back out in a straight line etc etc when for X amount of rounds he had been careful not to. But lucky, that's a bit unfair. Boxing is often compared to a game of chess. But in chess at any kind of decent standard you have to prepare your finish from a long way back, in boxing you don't have to. You don't have to manoeuvre your opponent into the perfect position to strike, you can just walk up and plant one on the fucker.

A 'lucky punch' tends to have further chapters to the story. Rahman and McCall are prime examples. Chinned a guy once who came back to 'prove' that he was by far the better fighter and that they were the beneficiary of his poor judgement on the night, they got lucky. Again unfair. The target was there and they twatted it one.

Luck is something you have no control over. To truly land a lucky punch you'd have to never move out of your corner, blindly windmill punches and hope your opponent walked into one. Even then it's still only fortuitous You were hoping the divvy bastard was going to do precisely that thing. Ignore that last part
