The turn is a 4. He bets to put me all in (yes, after checking and calling on pre-flop and on the flop), and I call. He shows Ax (a 6, I think). His only outs are one of the three aces, or a 3 to make the inside straight. The river's an Ace; I'm done for the night, down $20.
Could have been worse, though. My wife got dealt pocket sixes, and the flop comes 69K. She and Trestin are the only ones left in, they both bet big, and the turn is another K. They bet big again, and the river is a rag. Tres puts her all in, she shows her 666KK, and he shows his pocket nines for 999KK. Ouch.
