What do you generally do when you are pretty sure that someone is drawing to a flush and it hits. Do you check and risk being bluffed, do you bet a small amount and then call a reasonable raise? Do you check call? I know there isn't one specific thing to do, but nothing works well it seems. How often are you folding on the river when the flush hits?

I think i just shoulda folded this one, i'm so happy that he was calling my huge bets just on a draw.

Checking is weak and you risk being bluffed out of the pot, i think i was either beat by a set or something or by a flush here, but it could have been a bluff.

And even though this was in a tourney it demonstrates the same concept. I didn't fold this cause i still had 9 outs and people generally don't just push allin when they hit their flush. Also i was a little tilty i think
