results!?

He can easily have trip As with a good kicker. He's not really going to put you on a flopped flush with the A on the board, so he probably thinks you had a flush draw with something and thinks he has the best hand. I don't think there's any way to fold, so it's a call.

Probably not. I'm sure you could have squeezed more out of him somehow someway on the flop/turn. Maybe he would have even called an overbet shove somewhere.

But even if your way of playing it was theoretically optimum against AT or 22, the fact that you posted the hand would make us believe that the river decision was close for you (although in your last post you claimed you found it to be an easy laydown so I'm probably way off base). Therefor it's very likely that it was so marginal that the next time you're in the same spot you would pick the wrong "side of the coin," and make a very costly mistake.

Don't get me wrong, I'm not calling you a bad post flop player or anything of the sort. I wouldn't limp with K4s after one limper, in MP. I really don't think anyone should (if they should however, that game is comically juicy). I can see K4s on the button with 1 limper (although I'd actually prefer raising to limping), but MP with a few people still to act after me? I'm dumping it 100%, and I think you should to.
