$50 K3s 5 handed push?

[ryanghall]

$50 SNG at a card club. 5 players left. Winner takes $450, 2nd takes $50.

Blinds 200/400 and are going up to 300/600 in 2 mins (they go up every 15 mins so it's a quick blind structure).

I have 2100 chips left. 3 people cover me and one has a little less, maybe 1500. One of the stacks is quite a bit bigger than the others and he's directly to my left.

These are mostly not good players. At first, they were calling too much but with the blinds this high, they're now probably not calling enough.

I played very tight until it got down to 6 players and then I opened up my game, although for the last 5 hands or so I've been quiet.

I look down first to act and get K [img]/images/graemlins/club.gif[/img] 3 [img]/images/graemlins/club.gif[/img]

Push or fold?
