There will be times when you hit your set, make a moderate-good sized bet, and have everyone fold. Then you say to yourself, damnit I should have slowplayed.

Then there will be times when you slowplay flop and turn, and you are stuck with a scary board on the river, either winning a small pot or losing a big one.

I really only like slowplaying the flop if theres only 1 or 2 other people in the pot with you. I never slowplay the flop and turn - if they don't have anything they won't call you, simple as that.
