WBCOOP Preliminary

Played my first game at WBCOOP - NLH, first few hands and I got busted - I was a small blind and played HU aganst bb - folded to me - I was holding A9 made a small raise, got called and the flop was AAT i checked, so did the opponent, turn came 9 (dream card) I check and the opponent bets i just call, the river came Q and I check again, hoping BB has at least an Ace or has made a strait - he bets about one third of the pot, i raise the pot he reraises me all in I call - my trap worked! - turns out he had AT - got busted. Still can't believe it... well, better luck next time, hopefully...
