10/3 raising and then flat calling you are against KK/AA here pretty much 100% of the time, and probably KK since he didn't 3-bet.

Only hand you are scared of on that flop is AA but after your raise you were pretty much committed anyway.

Actually, button cold-called MP2's small $1 raise (after 2 limpers), then cold-called Hero's $4 reraise. Weird behavior for a 10/3 player. He's gotta have TT+, AQs, or AK.

On the flop, button bet about 60% pot after Hero checked to him, then felt pot committed with a middle strength hand and stuck the rest in. I think Hero's up against AQs, AK and TT-KK enough for this to be profitable. If he's got AA, why no reraise after the initial $1 raise?

Yeah, I agree there that the no 4-bet means no AA at that range and he's hoping for a set, thinks hero might be playing an underpair and repping the A there.

LOL. You both lost money to the rake. Villain must have AK and you both chopped. I've seen this type of play happen many times. If Villain had AA he would have pushed all-in pre-flop.

Looks good to me.
