I bet potted preflop to try and isolate. The table was weak/passive pf. I'd much rather go HU with this hand.

Semibluff on the flop bet, he was playing pretty weak.

WTF about the turn?


(Looks like a Ribbo style bluff he talked about earlier in another thread, Instead he bet out from the gun if it checks around.)

Seems like an easy fold, but the check/call, pot bet, didnt make any sense to my feeble mind...

Did he set the flop?
Aspade, another spade + lo draw?

Bet kind of threw me off enough to almost call.....

What is your line here?

My read would be a set of queens. The check-call was a little strange after the flop. However, the turn bet is pretty typical. He has you on A2 and wants to bet you out of the pot so that he doesn't have to split if another low card hits. He's also worried about you hitting a flush if the river is a spade, or losing to a straight if another low card hits. He's just protecting his hand.
