Hai Guys.

Op: I think I like the flat on the flop here with the As, makes it hard for him to have too many flush draw combos and makes us like playing on spade turns. It's fun to let the random spazzy fish, which this guy could very well be given this flop line, keep going nuts here with terrible hands.

Pretty sure you should just be raising this turn though especially vs this sizing. I'd be pretty shocked to see someone donk this flop then bet this amount with a set here. In fact I'd be pretty shocked to see this flop line from a set like ever at these stakes. So yeah, I'd raise turn and jam river pretty happily since I expect to see Kx way more often than anything else.

As played don't think river is close, pretty easy raise vs this sizing. You're good so so often vs this bet and good pretty often vs his calling range to a raise given it's prolly wide based on the fact that the way he's played the hand is really indicative of him being a fish and not being able to fold Kx on the river. I'd make it $9-$10ish.
