i didnt know that my FD draw was dead...it appeared that i only had gut shot to beat him :S

Normally I'm ok making a big raise all in with your hand figure you have 12 outs and fold equity the majority of the time. Here is the problem with your play, your opponant minraised you on the flop and you are making the 3rd raise to $15. This is the part I really dont like. First off villlian minraised on the flop which is usually a sign of stregnth, most likely he has a Ace here or possibly better. The more conservative way to play this is to just call the $3 and hope you peel one off on the turn, his min raise gives you a very cheap look at a card to beat him, the min raise usually means he's pretty attached to his hand and your fold equity is marginal. If you are going to reraise, I really hate the raise to $15, if you are going to put all your money in on draw just push, put all the preassure on him. Also what happens when you make it $15 and villians smooth calls and you blank the turn, now you are in a big pot out of postion with a draw and only one card to see.

Rhound said what I was going to say, only better.
