I check here alot because it's an action killer for your hand and you want to keep him in. I'm not folding at any point though.

Pre I like the flat with the unknown (likely fish) in the pot. Against 2 regs 3b is fine here .
Flop is a c/r on this texture against a bad reg. Sizing is on the small side considering a psr is to 72 so I think I make this a little bit bigger.
