Villain sat down with a full stack a couple hands back, so no reads. There was a 60/8 donkey with a ton of chips at the table a moment ago, but he went into a tailspin and Villain busted him when they got all in on a KQx flop in a limped pot. Villain's KQ held over donkey's JT. I'm about to stand up but don't uncheck auto-post in time. I'm dealt
[Kc]. Mmkay...
Folds to Villain in SB and he makes it $6. I make it $18. He calls. I start the hand with about $350 and he covers.
Flop ($36)
[6h][4h] He checks, I bet $28, and he calls.
Turn ($92)
He checks, and I?
Suppose I checked behind.
River
He quickly bets $90. Call or fold?
