I understand 4betting as a bluff here but given his size I really dont want to have to fold to a shove I think playing a sizeable pot IP is better imo.

I opened 4x because the BB is a loose fish and I want to play a pot IP against him. His stats were like 40/3 over 100 hands. so my line of thinking was SB made the smallish 3b to fold out the fish who wasnt playing too many reraised pots only single raise.

I was playing a few tables so I didnt think it through all the way but betting about 0.75 on turn would leave villian with 2.10 or so and the pot would be roughly 3. When he checks river and I shove his calling range has been narrowed to basically thr nuts regardless of river and theres only so many nut hands that he can have given his flop flat and turn check.
