okay now i've read everyones replies i feel the need to lecture a little on TOURNAMENT STRATERGY. you have 1700 left! that's 34 BB. thirty fucking four!! and you're thinking of PUSHING?! jesus fucking christ you have a playable stack behind you and you're going to push when there's every chance someone has checked with J10 or a made flush. i thought we stopped overplaying AK after we broke through .01/.02 limit?! would you not check that board if you had J10 or a made flush? OF COURSE YOU WOULD. and who knows one of the two players before you may have. but OH NO LETS PUSH AND HOPE. terrible terrible tournament play. at such an early stage. you have 6 BB dedicated to the pot and you want to chuck the remaining 34 in IN HOPE. i'm disgusted. wheres the spanking smilie when you need one??!?
No way is pushing "terrible tournament play."
It's a good flop for your hand, given the pot to stack ratio. PLENTY of worse hands can call a push on the flop including other 2 pairs, gutshots with flush draws, pairs and gutshots even. Maybe some kipper with just an ace. Early doors of tournaments there's lots of bad players' chips about which you should be aiming to pick up. I've seen allins on flops like these called by A2 at least in tournaments up to 100$ level.
If you were deeper to the pot, then you could play the hand more cautiously. As it is, I think it's bad to bet and fold to a riase and bad to check. Therefore, pushing is ok. At less than 1.5 x the pot it's hardly a massive overbet! (1700 into a 1250 pot)
Of course you sometimes run into a flopped bigger hand. This is pretty unfortunate but when you do you'll have outs. Most of the time you will pick up the pot right now or be called by an inferior or possibly coinflipping hand.
I don't mind making a half pot bet either here, willing to commit to or even possibly pass on a bad turn. If it gets raised on the flop then I'd be going with it, bar some unusually knowledgeable read I had on someone.
