weak, or way to weak?

[soonerorlater]

Bellagio 15/30. A few players have just switched out so the table has no rhythm. Villain is a young fellow, new to me, and has shown down a couple big pairs that he played strong/straight forward the whole way. Other than that he is unknown.

Player in the CO posts both missed blinds. All fold to him and he checks, I raise red QQ on the button, SB folds villain makes it 3 bets from the BB, poster folds and I make it 4 bets, he calls. It's a 5 bet cap.

Flop Kd 6d 6h. He check raises and I fold.
