Final Pot: 15.75 BB


I thought the preflop call was ok here - 2 cold callers and I am in late position and would probably get at least the bb to call if not one more.

I thought it was ok to cap this flop since I am punishing the flush draws and even if I am up against one I have 7 turn outs and 10 river outs so I am making money by capping the flop.

On the turn I bet to make flush draws pay. When I'm raised I assume the button probably has the flush. I call and my plan is to check/call the river but it's checked through.
