KK, on a low diamond flop.

[ahnuld]

Playing 2.5-5 nl on prima poker site. Just sat down, still first orbit so no reads. I pick up two black kings in late midposition. Someone from up front min raises. While i was waiting to post I saw him do this twice so it doesnt mean much.

Folded to me, so i raise to 40. He is the only caller

87 in pot. Flop comes 4 [img]/images/graemlins/diamond.gif[/img]5 [img]/images/graemlins/diamond.gif[/img]7 [img]/images/graemlins/diamond.gif[/img]. He moves allin for 92. Do you call or fold and why?
