I thought that with 3 bets I had no chance to win the tournament, with 4 bets I had a little room.

I just got it in my head that he had to have 2 pair here, everytime he had made this sort of play he had a hand, he was playing pretty straight forward up to that point in heads up play. I realize that that is a great spot for him to bluff. I just couldn't take the chance.

Edit: your probably right though
