Seemed like an easy fold after the bet and raise. I was worried about a bigger flush draw here. My question is, if there had been just the bet and no raise, can I Raise the flop with my pair+open end+flush draw? Notice I have 2 outs to the straight flush. Sorry if this seems easy, I'm just learning this game.
