I had a good read on him, he was super aggressive, but didn't usually call someone who raised preflop. I felt like betting that flop, but I felt like he would probably try to take it away from me on the turn if I checked, and I figured I had at least 12 outs if not 15.

On the turn, I felt like raising him, but knew unless he had a face spade card, he probably wouldn't call, and on the river, I figured he would think I was trying to steal the pot since he checked to me.
