BB vs Huge Chip Leader

[jazzcom]

10 person SNG, 5 players left, 3 players have around 2200, Hero has 2000 (after posting BB), Chip leader, playing his stack quite well with lots of preflop and flop aggression, has 6400. Blinds 75-150

Hero dealt K [img]/images/graemlins/spade.gif[/img]J [img]/images/graemlins/diamond.gif[/img]

Preflop: UTG(Chipleader)raises to 350, 3 folds, Hero calls.

Flop: K [img]/images/graemlins/club.gif[/img]10 [img]/images/graemlins/heart.gif[/img]3 [img]/images/graemlins/spade.gif[/img].
Hero checks, UTG goes all in, hero?
