BB and I have a bit of a history. He started off the session by buying in for $5 and pushing every single hand. He did this until he lost $25 (20 of it to me in 4 consecutive hands). After this, he sat out a round, then bought in full and seems to be playing tight. He pushed one hadn preflop, everyone folded. We played a hand where we both flopped the same non-nut straight and he called down. Then this hand.

I would cbet flop. The flop is fairly non-scary and chances are it didn't hit anyone, you still can improve with 2 strong overcards.

As played I would snap call this. I think that villain has a lot of worse 2 pair combinations. I doubt he would play a set like this. The only thing to be scared of here is a flush but I think that this is a small part of this range and you're good here enough times to make a profitable call.

that's the beauty of playing as a maniac, who knows what he has, and he's more likely to get an overbet called when he hits his draw. I have to call this, but i'm also reaching for a reload with my other hand.

I cant see letting this go. Its very possible he could have made his draw here but because hes a maniac its equally possible he has something like Ax. Like allbad said, i make the call but at the same time don't be surprise if he may have made his draw.
