I'm in this tourney and the blinds are 750/1500 with a 150 ante. One guy calls the BB and I have Ac 7s and just limp in with the small blind, the BB checks and the flop comes 2d 6c 7h. I'm first to act and I only have just about 6 BB's left (8,800 chips) so I decide I'm gonna try and take this down now and I go all in. The BB folds and it comes to the only other guy in the hand, he's got me covered by 2000 chips and makes the call. Our cards flip and he shows Js 9s. He's got 2 over's but no straight/flush draws. The turn is the 6d, still safe... and then the river comes 9d. So he ends up calling away literally almost all his chips and lucks out on the river to save his butt. I can't imagine what this guy was possibly thinking. Maybe I played that all wrong, I don't know, but I feel like I should have taken that pot down without ever seeing a turn or a river, especially knowing what his cards were. Was I wrong for pushing, or did I just get unlucky and run into a donk who got lucky?
