Simple preflop situation: UTG raise, min reraise.

[pzhon]

Online NL, 9-handed.

Hero (UTG) has the table covered, and has been playing tightly.
Villain 1 (UTG+1) has 22 BB, and seems pretty loose.
Villain 2 (MP2) has 32 BB. No read.
Most players have 80+ BB.

Preflop:
Hero raises to 4 BB. Villain 1 calls. 1 fold. Villain 2 raises to 7 BB. All fold to the hero. Hero...?

What bugs me about this reraise is that I have represented a tremendous amount of strength by raising UTG against the other deep stacks. I usually don't raise JJ or AQs UTG. So, what hands are a favorite against the range I'm raising? Only KK and AA. Perhaps the smooth-call by Villain 1 would encourage QQ or AK to get aggressive. Perhaps Villain 2 hates money and has TT. However, I really feel I'm behind on average and out of position. Can it be right to fold KK to a mininimum reraise? If I call, how should I play on the flop?
