KK preflop - do we push here?

25NL
Villian has ~25$, hero covers.

Villian is BB, Hero is UTG.

Hero gets K [img]/images/graemlins/club.gif[/img] K [img]/images/graemlins/heart.gif[/img]

Hero raises to $1 (4x BB)
Folds around to villian
Villian reraised to $10 (40x BB)

Hero...?



Of course we are not folding, but how do we play this? A flat call will make us very angry if an ace flops as we will regret having to either fold or put rest of stack in.

Push is best, right?
