I like $12-$15.50 on the turn, a nice little blocking bet (assuming it's a blank). If he raises we can assume we're beat most of the time. I realize this is a donk lead, but he's raising on the flop a lot of the time to get a free river with a flush draw. If you 1/2 to 2/3 pot it he's definitely going to raise you with a set, probably call you down with some of his Ax hands, you're basically putting him to a fold or shove test by the river.

If he flats our turn lead, I shove any non-diamond/non-jack river. If you hit a Queen on the turn I would say to c/r AK/AT, or possibly commit a flush draw to bad odds. If you hit a Queen and the turn goes check-check, I pot any non-diamond river.

I just hate lead checking on the turn if a blank hits, we'll get bluffed so much more often. If you're willing to possibly call $9-$12ish on the turn, I say open for a little more than that for fold equity and probably fold to a raise.

AQo TP2K on a draw heavy board oop facing a raise by the preflop aggressor is just an ass spot to be in. You find that half his range you're killing and would like to use blocking bets to protect your equity, half his range is killing you and you really want a cheap showdown. In WA/WB situations like this it's almost always correct to b/f the turn, if he can raise napkins in this spot I'd have to say nh him.
