AKo - made trips on river, facing raise.

[pokernicus]

Thanks for all the replies! Here's my (brief) analysis of the situation. The hands I have to be worried about the most are Kings full or a straight. However, in both cases, I would think he'd raise the turn. Since he smooth called the turn bet, I was thinking that he likely had a K with a weaker kicker than mine.

Based on the read, I three-bet the river. Button called with KQo and MHIG.
