KQ is a likely case, I agree the river seems like a top-pair block bet- and a flopped oesd with 2 overs seems to play this way. Also, a set seems doubtful- unless this guy had the ability and foresight to fastplay three fives without making it obvious he feared the draw.

Put this guy on JJ or TT and you're giving him a helluva lot of credit in terms of playing ability. I agree that Joe Poker would put his money in by the turn here with that type of holding. QQ is possible... but... no heavy pf or flop action.

My conclusion is that- as is common with large bets- villain has a marginal holding. QK , JT, or QJ. Either would've been quiet preflop, led the flop, continued the turn w/ a blank, and have confidence still on the river (he didn't overbet it like a missed draw or made set, either...)

You lose the most money on the hands that you slightly trail (overpair v. 2 pair, 2 pair v. set, set v. straight...) and vice versa (IMO) b/c the betting patterns don't indicate whether you're cleary behind or ahead... you're just - somewhere nearby.

I say KQ read is merely a temptation for the hopeful- I pitch the cowboys and save myself the 30.
