He's called 2 on the flop so he's either probably drawing to a straight or flush. I wouldn't discount another T here though, cos you always wait until the turn to c/r your top pair, right? [img]/images/graemlins/smirk.gif[/img]

I think your hand is quite vulnerable, if not already well beaten. I probably b/f here too, but perhaps checking the turn and folding the river UI would be better?
