Call, Raise or Fold?

[manku]

NLHE tourney on Pokerstars, 180 players, 100 buyin, 1500 chips.

Down to 120 players or so, 25-50 blinds.

I'm dealt AQs on button and (1700), a little under average), raise to $300.

SB, goes all in for $650.

BB calls after long time.

All others fold.

I'm sure there is an ace out there (most likely SB) and BB probably has medium pair. Also, BB has me just covered.

Assuming that my read is correct (which, in fact it was), what is the right move.

SB had A3, BB JJ.

Thanks.

Did the original raise need to be so big ? Because it was you surely call, and see what flops.

Its a call/fold scenario.

One day call,one day fold.If it was AQo its a fold.

Realistically in this scenario I would take the flop and hope my flush comes.

I want it heads up with the allin. So I raise all in as well. You made a LARGE raise to start, so you should finish by going all in and hope the BB folds. I would expect to be up against an AK, AA, or KK for SB an pair of Jacks or Tens for BB(assuming this because he took some time to think before calling).

This makes no sense. You want to be headsup against the all and you put him on 3 hands that have dominated ?
