here is a hand I still have not figured out.

This is a hand I had in a 10 person SNG. The blinds were at 15 and 30. We were still 10 people and no one had really taken any big pots.

I was the button and was delt AA. I raised to straight 100. Everyone folded except someone in mid-position, he just called. My read on him was that he was conservative. I would say that he was probably a TPP. I hadn't seen him bet at anything yet. He had called a few blinds and folded to the first bet. So the flop comes 6-5-5 rainbow. He is to act first and pushes all in. I was caught totaly off-gurard . I thought about it for a while and folded. I thought maybe he had 66, and this early in the tournament I decided to fold rather than be crippled if he had 66 or 55 or just a 5.

What do people think of this decision?
