First of all: John Juanda flops a royal flush draw, checks the flop like a donkey, just calls the turn (which I like) and minbets the river into a 11K pot. I don’t dislike the play on the turn, but against Gus Hansen a player like John SHOULD cbet the flop for sure. Gus may have raised, who knows!
Against an agrressive opponent; i don’t advise EVER checking when you flop a good flop in position when you raised. Bet out – people EXPECT you to bet, and it can be way more suspicious to check!
