This is a discussion on Squeeze play within the online poker forums, in the Online Poker section; No Limit Hold'em Tourn.
blinds: 25k/50k ante 5k
Final Table: 9 handed.
UTG (8bb) open shoves KQs, Button(24bb) flats, Hero(bb) reshoves 15bb all-in with AQs.
From the button's perspective, depending on stack size of the small blind...it's weird that he didn't jam on any hand he's willing to call. If small blind had him covered and he was willing to fold 2s-6s to a small blind allin...then maybe I understand it. Otherwise, calling there is either a weird play or as you noted...trap squeeze attempt. It doesn't seem to make sense to do that though if small blind had similarly 15BB. Hero is going to jam or fold there based on hand strength in a 3 way pot. I'm sure Hero knows there's 0 chance that button is folding.
Well, without any fold equity it would appear the BB is, simply, getting his $ in w/the best of it. Depending what the button has, perhaps JJ or better, flat calling utg's 8bb's and hoping for one of the blinds to call could be determined as a trap-squeeze. I'll buy that.
