NL25 QQ in 4-bet pot pre-flop and flop line check

[willyc]

Villain is 50/30/8 and he thought for a really long time on the flop before betting a little less than half his remaining stack which looked really weak. Usually when someone has me crushed I see a check, a really weak looking bet, or sometimes a shove. He basically took the only possible line which convinced me I was ahead. So he's either weak here or playing this very well (which I doubt).

How's my play pre- and post-flop? I usually call a 3-bet with queens, but I'm starting to feel like that's not the best line since I don't get enough information and I usually find myself making bad decisions post-flop. And since there's a lot of 3-betting light even at NL25 now I figure QQ is definitely a hand to 4-bet with.
