Very little history to go off of, but in the hand previous I had open-raised KQs and checked down a low board to the river against the current SB.

I nearly folded PF, I don't like to play AQo in this early of position and in the tournament.

You gave him the hand by not firing again. You're so deep you can afford to take a stab again.

I think you played it fine. I probably call the river, though. If I'm not calling the river, I'm betting the 10 on the turn.
