[stigmata]

I disagree with the turn check. The read given was somewhat lacking, but against a vanilla fish:

1) He showed no aggression on the flop. The turn changes nothing -- it is unlikely he is paired.

2) He's a fish. There's a good chance he is just peeling. Our fold equity rockets on the turn.

3) We have no showdown equity and can't call a river bluff, getting a fold from him would be much better now. A turn check with a gutshot + high card would be much nicer.

4) We have a gutshot and it's an easy fold against most players.

Against 95% of players our fold equity >>> equity of our draw. Unless you missed out some vital information in your read.
