QQ against a fishie

[topspin]

I raise this turn. If MP2 has a 5, this is the perfect spot for him to check-raise and trap the field for 2, so I tend to think that him leading the turn is either (a) a donkified J or (b) a total bluff. You really want to face Button with 2 cold here in case he has some weird draw or overcards to your Q's.

Given your play, I'd just call the river. Unless villain has exactly Jx, your raise has no value -- a bluff is going to fold, and any other piece of the board beats your hand.
