2-5 no limit game. I pre flop button raised 35 with pocket sixes two callers. The flop comes 10 6 9 two spades the 2 guys checked I bet 65 guy to my left min raised next guy folds I call. The turn is a blank no straight or flush guy bets 325 I call the River is a 2 spades guy goes all in my last 500. I folded but thinking deep I think he was protecting 9s and 10s but he could've been betting the flush all the way. Think I should've called!
