I don't like preflop. 3bet like always.
I hate flop. People bluff on uncoordinated paired boards like there is no tomorrow. You respresent exactly one hand - 33.

On the river his range is very polarized. Its QQ, AA, JJ, AQ or a flush draw. He might have missed a c/r on the turn. But given that your flop range is very polarized too, I am not sure he would want to give spades a free card.

Basically my points are the following:
- your hand looks like air, flush draw or 33 no matter how you look at it;
- his hand looks like a flush draw or at least top two no matter how you look at it;
- his position says there are many more draws in his range than there are there are monsters.

Trouble is he might have the nut flush draw. So I am not totally sure here. I dont think he bets it though cos there is no worse hand in your range that you call him with.
