folding KK pf too tight?

[RikaKazak]

Hey all,

Villian is a 19/4 after 270 hands and he's 1.7 AF. I'm thinking should I call pf bet and try for set and release it on any A or Q flop? I was trying to think if he would do this with AK or QQ, and I really just don't see it, maybe I'm being too tight. BTW, I'm playing an 18/6 at the time, but only putting pressure on when I'm in late position. No 5,6s raise UTG like I usually do.

10 handeed 3/6 NL on europoker (eurobet) hero and villian have $650 stacks

UTG limp, MP+1 (hero) raises to $25 with KK folded to SB who calls, UTG limp raises to $123, so it's $98, hero's plan????
