Party 30/60: raised on the turn again

[34TheTruth34]

Here is an area where I'm having a lot of trouble:

Party 30/60, I am in the BB with 76s. two folds, An extemely loose passive player limps in next (he'd raise with his good hands) everyone folds to the CO who raises. Button and SB fold, I call, LP calls. three players.

Flop Q-Q-6 rainbow. It's checked to the CO who bets, I check-raise, loose player folds, CO calls. Heads up

Turn 4. I bet he raises. My guess is that this player is a solid, aggressive player (1000 hands, 20/10/2/44 WSD). His turn aggression is 2.8.

What's your plan?
