Ya a flush is definitely more recognizable. I really didn't try to put my opponents on any hands. Maybe if I thought someone had a little flush, I could have re-raised the flop and made him push or call.
Although I think the check on the flop is the best, because if that turn card isn't a spade I can get another bet out of them.
What do you think? Best flop play? Best Turn play? If the turn was a spade or non-spade?
