5/10PLO; I have $9200, Villain covered. Villain just sat but based on how deep he bought in for and from swagger I have an inclination he might be a bit splashy (just a feel I got). One limp, he opens CO to 50, Btn Calls, Hero 3bets to 200 with KJTs8s in SB. Villain min 4bets to $350 Btn folds Hero calls.

Hard to be accurate but IME these small 4bets are seldom AAxx, and more often hands that want to take initiative cheaply, still be able to call a 5bet.

Flop AcQsJs. 

Hero checks, villain bets 500, hero calls.

I dont think he has AAxx much and even though I have the redraw its small FD, lots of turns will be tough if I turn my hand faceup. 

Turn 7c. 

Hero checks, Villain bets $1500, Hero can make it $6200 and will have $2100 left. However I want to slowplay given I dont think he has AA; a hand that can call a c/r or that I need to protect against. 

That said, it would be quite a bad result if Im wrong and he does have AA+draw and would stack off, or he has KT and I miss out on my redraw potential. Board pair rivers are tough and even flush rivers too. I think just x/c turn and x/c or c/r river might be best. He could have a basic airball as well or blockers. Yet pot size is already $6200. Without a really strong read should I just go for the c/r given its certainly +ev?
