Sadly OOP here against a villain who is 16/14 in 75 hands with Agg Freq of 60%.
When he calls 2 streets, I'm thinking I'm beaten even if the flush doesn't hit. Could we even check the turn here for pot control? I see no reason to call his river bet either unless I'm mistaken?
At best, I'd be splitting with AK, but his bet seems to be screaming 'please call'...
