this happened today and I thought of this thread after the hand.
Limped pot 8 ways 2/5.
Flop 3
4
5
UTG Bets 40 (his stack is about 1000). UTG+2 raised to 200. Another player goes all in for ~385. It folds back to the original better who says "are you serious I have a straight" and folds 67.
He said he knows at least one of the other players are on hearts and he didn't want to risk the rest of his stack. When he said he had a straight I thought he folded A2 but he actually folded 67.
The board bricked out and UTG+2 hit a third king otr to take it down. I guess he was trying to limp/3bet.
Playing with people who will fold the nuts on the flop is not a bad thing. Fold equity is under rated.
