100NL: AQ vs. Middlestacker

[Kos13]

Sometimes, I 3bet this PF, but the original raiser had only raised once in the 40+ hands I had on him in my database. SB is ~25/7/1.5 after about 100 hands. I just sat down, and I doubt either player has any reads on me. SB's stack size makes this a bit tricky, as a decent-sized turn bet pretty much commits me to the hand.
