It doesn't matter what the read is. In heads up action you just have to go all out for the win. You probably ended up loosing the hand and that's why youy posted it here.

But if I was in this position, I'd go all out for it. And I would have raised a lot more once the flop came down. I would probably even bet out in this hand if I had 65o or 6To. 1 on 1 at the end of the tournament is basically; "he who dares wins". And you're stack is 5 times bigger than his. Just go for it everytime. Put him allin with a queen, king or ace in your hand, or any pocket pair. Put the pressure on him.
