Turn (4.75BB) 8 [img]/images/graemlins/club.gif[/img]
BB checks, Hero bets, MP3 raises, BB folds, Hero calls.

I am not confident in flop, cause rock called my pfraise, but I think on this flop bet and check/fold are almost equal.
I have not got enough pot odds to continue on turn, if any of my opponents have decent hands, but if they have only overcards, the probability of improving to the best hand on river and probability of my bluff success, make my bet more valuable, although I think the bet here is a bit overplay, especialy, if MP3 slowplay something like QQ.
Turn call is bad, implied odds are only 1:9.5-10.5, although I won this hand.
