The river is 3c, so I'm sitting on a pair of sevens with an ace kicker. Big blind bets. I raise to scare him off, because I'm pretty sure he's got nothing. He thinks a long time, taking up almost his full 20 seconds. I'm really, really expecting him to fold here, because if he calls, then it's probable that he has the jack but was scared that I had a big pocket pair.
He calls, my stomach drops, and... I win. As 7c 7s Js 6s.
Amazed, I go to the game log to find out what he had. He was playing Ac Ks, leaving him with Ac Ks Js 7c 6s. He'd gotten wedded to the hand, which cost him about $30 -- a mistake I'd made a few times Monday night.
I don't fold big slick nearly as often as I should. Not doing so can be a costly mistake.
