Questionable 3-bet on the turn?

[FlopMe]

The player in the small blind is a mouse: 11.73/3.57/2.38 over 196 hands.

The player UTG just sat down and I have no previous hands on him.

Would you 3-bet this turn? What about raising the river?

Looks good to me, I'm definitely 3 betting the turn and raising the river - given your read on SB you'll probably see the other Queen, if he has an Ace as well, so be it, he won't have it four times out of five.

I figured I wasn't going to win this outright but the chances for a split were good. So, milking the UTG player seemed like a good idea. It wasn't. AQ. MHING.

I 3-bet the turn. Call the river.

SB is a mouse. He is definately representing AQ on the turn. What the heck did you think he had? KQ for a split? After 200 hands do you really think he called 2 cold out of position with KQ. He is definately a thinking player (sure a little tight) but now you have to out think him.

No way I'm raising this river, he is probably free-rolling you.
