Sit and Go strategy

I've played a few Sit and Gos recently where the following situation comes up:


3 players left...2 large stacks (~6000-7000) chips) and 1 short stack(<1000).

Blinds 100-200

I'm Dealt AQ on the button. I'm one of the 2 big stacks.

I bet 600
SB (short stack) comes over the top and raises all in to 800
BB (other big stack) calls.
I call.

Flop Q-J-6 rainbow.
SB is all-in already
BB checks
We?


In any other situation I raise it up about 3/4 pot, but what I've also considered is that if I check and keep the other big stack in I increase the chances of knocking out the short stack.

What I mean by that is, if the turn and river help the short stack somehow and he ends up beating my TPTK there is still a chance that the other big stack could knock him out, thereby guareteeing me at least 2nd place.

So sometimes there seems to be a mutual agreement between the big stacks to just check it down to the river and hope one of us knocks out the short stack.

Is this good strategy? Or should I be raising to get more action or a fold from the other big stack?


Thanks,

As for the hand, I don't think betting or checking down would be a terrible mistake here. Haven't played stts in a while so I unfortunately don't have much to say, sorry.

I'm assuming if you're down to three then you're already in the money?

I don't think there's such a big need to check the hand down just to knock a player out once you're in the money - I'd figure you're justified in betting and trying to build up a lead for the heads up portion of the game, seeing as how everybody's getting paid anyway.

depends on how much money you want to be guaranteed...check it down
