vs fish fold to 3b 0/4 f to cb 34% and 50% in 3b pot out of 4 situations.
He is also pretty passive postflop

I cbet flop and don't expect to take it down to often so is for semibluff/thin value
On the turn i may have sometimes the best hand, but not to often and i put a blocking bet for him to call with weaker Ax KJ+ and low to medium pairs, and plan to fold vs raise.
On the river just want to see showdown
