Well, if I call, then I am putting in about 100 chips to the 200 in the pot and that 2:1 is probably not enough just to see one card as the odds are 2.9:1 to get the flush or an Ace on the turn.

If I go all in and put them all in then I need odds of 1.2 to 1 in the hope of making an Ace or a flush (12 outs) with the turn & river. I think I am getting these odds as I have to call about 100 making the pot 300 and then raise all in about 850 so:
(his 850 possible call + 300 pot) divided by my raise of 850 is 1.35:1

I think that calculation is right?
The question is whether I need to do this and because it is a big 2000 player tournament whether I would be better to make this move and increase my chip count fairly dramatically?
