Should I have gone all-in?

I was in a cash tournment last night. The blinds were 100/200. I have 1900 left after the flop. I'm holding . The flop comes:



This player who is the chip leader and plays nearly every hand raises it to $1000. I figure I'm shortstacked. I have middle pair and both a straight and flush draw. I push all-in, He calls. He's holding .

The turn and the river was:

.

Do you think I should have just called? If I did, I would only have 900 left and I would have been in a bigger hole. What do you think?

No, cant call - you either go all-in or fold. If you think he's bluffing go all-in, if you dont fold - you were the one that was there, so I presumed you thought he was. Problem is, saying it's a middle pair is fair enough, but there is an ace on the board which is always a danger sign, and saying you've got a flush draw is a bit spurious! And, saying you're short-stacked - you've got a few rounds of blinds left so there's no great rush.

I would have folded, unless i thought he was bluffing like rob said... I don't consider runner runner suit a flush draw either. Middle pair would have looked alot better if the top card on the board wasn't an ace. People play Ax, especially chip leader...

EDIT: after re-reading my post, i basically am backing what rob said

I figure I'm shortstacked If you figured that.. the all-in should have been done pre-flop.. by constantly calling pre-flop you are only losing your chips anyway. Might as well try to double or even triple instead of calling, callling, calling every hand you think is good.

You still had enough to see a couple of rounds. It is hard to push all in when there is an overcard, especially an A. Loose player seem to love to play Ax.

I would fold here and just go all-in preflop with my next good hand. Put the max pressure on preflop.

No way you should call. When you make a call you have to be prepared for later streets´s action. With your opponent holding two pair, don´t you think he would bet in either the turn or river? What you have done there? You cannot think of calling in the flop and then folding in the turn with 4.5xBB remaining.

That aren´t good reasons for going all in. That quote to me sounds like as you knew that he had you beated. In those circumstances you don´t want to be all in. Remember that you can´t apply EV when you are the one that is all in in a tournament, because there isn´t long run. So those draws weren´t enough reasons to call (actually you just had an inside straight draw, unless that A in the flop really was of hearts). As rob said the only reason that would have made you went all in was to think that he was bluffing.
Twizzy made a very interesting point. When you´re shortstacked is a bad strategy to keep calling preflop in hope of hitting something and then go all in. Save those blinds to wait for another round of hands and go all in preflop with maybe pocket pair or Ax.
Anyway 1900 with blinds 100/200 isn´t that bad. You have time to wait for a good hand to go all in preflop.
