What do you guys think?...

We have AQ off in BB (9 handed). Solid player opens from utg+1 to $20, called in mid, we complete from BB. Flop q73 (2 clubs - we have none). We check, utg+1 C bets $35, gets raised from mid pos plr (we have seen him raise fold flop to 3 bet earlier - even after putting in 60% of his stack - at the time was 400)...anyhow mid raises flop to $85... we 3 bet to $190. Utg+1 folds. Mid calls. Turn card Kd. We...?
(Stack sizes are around 120 BB. Pot size bet remaining).

What's your action on the turn and why?

Cheers,
T.
