My first reaction is: Why do you raise the flop here? . . . you got a lot of folds but thats bad when you are drawing! You want people to call when you are drawing . . . only raise to protect when you have something worth protecting. (Ace high??). If he has a pair of T's you really only have 3 A outs (maybe 1.5 for flush, 1 for straight) that may not be any good if naybody has a bigger ace. I would probably fold (or call if the table is loose enough that everyone behind you will call)

On the turn You can't really raise for value against 1 opponent with the flush draw you picked up. Are you hoping he will fold? He called your C/R so he probably has something or a really strong draw.

Why do you raise the river? He has called you down so far . . . (if he is thinking) he most likely has a pair of T's with a kicker not quite good enough to raise with . . . Do you put him on a busted draw?
