Villain's 50/30 over a tiny sample. He's been pushing people off hands and that's how he accumulated his stack.

What do we think?

Here's how I saw it, guy obviously likes to throw chips about so in position with A5s I take a flop. I only do this since we're comfortably over >100BB each so there's heavy implied odds, especially due to his stats.
I hit a nice flop and call because, again, we're both deep and he seems willing to bet and it's not too expensive. I planned to fold to a non-heart barrel on the turn but I pick up some extra outs so I call here too needing to hit badly.
River bricks and he checks, at this point I thought he could have AK, it's a common whiffed AK line imo. But then I thought maybe AK bets stronger on the turn so I thought he might have a piece, Qx perhaps, or maybe like me, a missed draw. I feel he's capable of laying down Qx so I fire just under a PSB.

Critique away!
