FOOLS RUSH IN

I was recently playing in a $100 tournament where there were 187 runners left from a field of around 1,200. The last 100 got paid. I had a stack of 3,250 (slightly below average) and blinds were at 400/800. I picked up K♣-4♠ on the button. The small blind had 7,500; the big blind had 3,300. It was folded round to me. Should I have shoved in this spot?

The first thing you have to look at in this situation is your table image. Have you been aggressive and stealing a lot of blinds or has it been a while since you made a move?
