Early Tournie Question

Playing a $3000 tournie... $150k to the winner, 170 runners. Everyone has $10000 in tournie chips. Levels are 1 hour long.


Third hand of the tournie, blinds are 25-50, first position player limps, I am in second position and find KK, I raise to 350 to play. 4 callers! back to the limper who moves allin. I know absolutely nothing of his play.


What should I do?


Cheers,


Keith
