Your talking about the odds he needed to call if he knew what your hand was. This is a 4 player tournament so raising standards have to be more liberal then in a full ring game and it down to just SB/BB so it's effectively heads-up for the hand. Unless your raising standards from the BB in this situation are only pairs and big aces then he probably figured there was a good chance he had the best hand.

When you checked behind him on the flop he figured you didn't have an ace and after betting 400 on the turn and being raised all-in he had only to call 700 to win a pot of 1800 chips which is 2.5 to 1 on his call. I'm sure if he's as wild and loose as you say then that's more then enough.

I'm not saying this guy hasn't put some terrible beats on you in the past but I don't see anything out of line with his play on this hand.
