I haven't read a lot of the replies to this hand. This way I feel like my opinion is untainted. I'm sure others have mentioned that you have a better draw and it is worth the call. But you still only have a draw. Let me type this out and figure the outs involved.

His outs are 2 Ts, 2 Js (not the Tc or Jc) 3 Q, 3 7s. A total of 10 outs. I'm assuming the rag on the flop was not a diamond and he didn't have a backdoor flush posibility.

That's a lot of outs he has. I could mention the outs you have but it's basically everything else.

OK, and you are calling $180 into a $250 pot. If you knew his hand, then you knew you were a favorite, but a weak favorite. The decision is yours. Even though I am a favorite, it would still be a tough call for me.
