I am not sure with the turn play. I think i can mixed it up between checking and betting. The reason i checked here is because i don't think i have much fold equity OTT (just to make it clear - i did not check because i hit the 4 OTT and think that i have SV), because he usually has a pocket pair. + I have As, which blocks hands which doesn't have a pair. I would ceirtantly bet the turn on K or A, because they are scare cards. As played, river is a fold, like i said, he doesn't have many bluffs here.
