NL100 KQs OOp vs fish. floped GSD+overs

38/20 fish, very loose calls a ton preflop --> so pre is for value
He had already called one SQ in same position nad folded to my CB on dry flop.
I sort of wanna fold out all trash on the flop Ax, small PPs, connectrs
When he shoves i need 31% equity to call given odds, and i guess with GSD+overs i sort of have to call (~38% equity vs AJ hand)
meh.
What are my other options on the flop? can i CR? can i ch-fold?

If I'm not sure about calling AI, I'm not cbetting. And this is the hand, where I'm not sure, so I would check/fold


- I think the biggest problem with this hand is: if you are cbetting here 20bb you are commited to put another 61bb into the pot, because it is drawy board and there are a lot of monies there for fish, so it is big chance, that he will play back on this board and against that range I think you probably have 31%
- so cbetting seems like unneccesary high variance gamble, but I'm 50NL fish, so I can be wrong....

yeah think this is a a call for the reasons stated + you're ahead small amount of time vs q10/78/810 etc.

I think I'd just c/f but I don't hate c/r or b/c. Probably wouldn't squeeze pre but that can't be too bad either.
