Maybe it's ignorant of me, but it doesn't make a lot of sense to me to be this terrified of flushes in hand 2. I raise 4xBB pre-flop under the gun, showing a lot of strength, and this guy re-raises to slightly less than twice that amount, and I re-raise him to more than twice his re-raise, which he calls with. What's the worst hand I'm really up against here, AK? Maybe a pair of nines? In either case, with that flop, I don't have to be worry about a flush draw unless we're talking about a runner-runner flush draw. And if it were AK, then he ought to be betting like a madman on the flop, if not on the turn.

No, those bets say to me that he's got a big hand that's scared of both the ace and the king. In terms of why would he not call the flop or turn bets when he called the river bet, well, I'm pretty sure that by that point I had made him think that I didn't have the ace or the king, and because I was betting less than the pot, he thought it was a good risk for him to call the bet. Had I bet that on the flop or the turn he probably would have folded.

As for how exploitable this makes me, I don't think so. If I thought this player was even remotely clever I wouldn't have played the hand like this.
