K7s on the button
 

UTG is loose passive (55/2/0.7) and limps UTG. It is folded to me on the button. I have K7s. The blinds are both 2+2 kind of TAGs. In other words they don't over defend but they are not super tight in the blinds either.

Easy raise?

I think it is a close raise. I would definetly raise A7s, and K9s. K7s is a stretch, but I think profitable given those exact circumstances.

Raise it when both blinds are capable of folding. With loose blinds, call. If UTG is decent, like 35 VPIP, then fold.

I don't really like the raise. I'd raise K9s, KT, A9, and 77 here and probably pass on the rest. If you had a more specific handle on the postflop play of these three, particularly BB and UTG, you could probably get away with this.
