Hey all, first post to MTT Strategy. Not sure how interesting this hand is as I don't play much tournament poker at all. and sorry, converter wouldn't work for me. anyways, here's the hand.

blinds 170/340 with a 25 ante. i have 4300 in chips, so an M of about 6. there are about 950 players left out of 3400 and top 140 get a seat in WSOP ME.

4 folds, guy with 9000 in chips makes it $1500 to go. he's been raising in middle/late position, but not a crazy amount. this bet seemed proportionally a bit larger than his previous bets in earlier blind rounds.

folded to me in small blind and I have AQo. note: I've only shoved once so far (over a perceived button stealer) a few rounds back and wasn't called.

What's my move here and why? Thanks.
