AQo in $30 Party NLHE

[yecul]

$30 Party NLHE, down to <60 of original 878. ITM but obviously final table is the place to be.

AQo in EMP with blinds at 1.5k/750. I have 15k, about average for the tournament overall, and middle of the pack for my table. Everyone's been pretty tight and not getting out of line.

Slightly larger stack than mine makes it 6k to go from third position and I'm next to act. What's the move?
