In this hand I was paranoid about sets, after seeing them win against me so often, and so took my foot off the gas on the turn. And look where it got me..

I was surprised he called that flop bet though..

Hmm.. Yes, I think I should have semibluffed that turn for around two-thirds of the pot. Nice comment.

But set paranoia is paralyzing. I will have to work at playing each hand in isolation, rather than thinking that history will repeat itself and kick my ass again.
