UTG is a fish who just joined the table posting the BB from UTG, playing 53/1 on 101 hands. The CO looks like a reg , on 119 hands playing , 27/22 , agg factor of 2.1 , CO rfi 27, flop cbet 71, fv3b 14, 3bet 6, fvcbet in 3b pot 0(3).

I assume his rfi range of 27 from CO is wider when iso-ing a fish. Do you 3bet here or just call and let the fish call too?

The fish folded so it's just me and him. I check , he bets, i call. All standard, but let me stick this in, do you ever consider check raising here?

After calling otf this feels like the only line.

Right here i don't think we beat any hand from his value range. As far as cbetting goes the small sample i have on him produced the following stats: Flop Cbet 71(8) , Turn cbet 100(5) , River cbet 100(1) with an agg factor of 2.1. Based on the available information, do you bluffcatch here?
