Hero (CO): 100 BB

SB posts SB 0.5 BB, BB posts BB 1 BB

Pre Flop: (pot: 1.5 BB) Hero has A♣ J♠

fold, Hero raises to 3 BB, fold, SB calls 2.5 BB, BB calls 2 BB

Flop: (9 BB, 3 players) 6♥ T♥ A♠
SB checks, BB checks, Hero bets 5.5 BB, SB calls 5.5 BB, fold

Turn: (20 BB, 2 players) 5♣
SB checks, Hero checks

River: (20 BB, 2 players) Q♣
SB checks, Hero checks

Flop: I bet a bit on the high side to charge the draws, a lower ace and to thin out the field. Yes, there can always be a set or a wacky two pair, but that's life. Looking back, I think I should have bet even more, like 7c

Turn and river: looking back, I should have bet turn and maybe check river, because all the busted draws would fold, and now QT has me beat.

Opinions?
