[NL200] Bottom set 280BB deep vs 3 bet on flop. I want to fold.

[13_Xerxes]

Villain is a solid 27/17/1.67, maybe a little passiv.
I am playing very nitty.

I call PF to set mine, of course, and I hit a beautiful board. But his 3 bets, so deep is soooo scary :
- overset (99/TT) ?
- big PP who wants to know where he is (but so deep [img]/images/graemlins/confused.gif[/img] ) ?
- semi bluff with a draw ? QJs/78s ?
- AIR ?

Can I fold, must I 4 bets, just call ?
