Preflop: I am not going to get too frisky in the BB. I generally don't raise in Blind on Blind confrontations unless it is in a tourney.

Flop: His check raise seemed really...off for his play and I was playing 2 tables with him so I had gotten a feel for his play. Plus I do have outs.

Turn: That didn't help anyone. After he bet, I was fairly sure he had the flush draw and no 6. I didn't want to raise him incase I'm wrong and he might just come along with the flush anyways.

River: That 7 scared me a bit, but I was still 90% sure I was ahead. I was calling any bet up to the pot. He would have to push to get me to fold.

I think that a raise on the river would've been a good move incase he had the A-high flush draw. In retrospect, that was a pretty big mistake.
