Co is a presumed weak player and SB is a reg 24/19 (577)

Preflop
I am ahead of their ranges and AQo doesn't play that great MW OOP.
SB is capped and if CO shoves I think I can call given his stack size.

Flop
If this hand was HU I'm cbetting this flop but since we are MW I think this flop hits their range well. Also CO might play pretty honest and let me get a free card.

OTT is where it gets kinda marginal? SB doesnt use a 3B/F strategy vs LP and I'm not a very aggressive squeezer pre. Is it too optimistic to think he might be betting some of his Khxx (KhJx, etc..) along side his GS with hearts like 99, or OESD 88 and his value?
If he does then we have a profitable call in terms of equity and I dont expect CO to shove all that often and if he ever calls he just improves our odds.

OTR he checks. I thought B/F was better than a checkback. We dont have SDV and his checking range has some hands that will fold.....

It worked this time but perhaps my thought process is all wrong.
