It's a live tournament so the exact details are a little sketchy but I wrote it down soon after.

We are at the 600/300 75 ante ….level 5 I think?

I've got about 22BB and I'm on the button with KQo.

My image to this point has been tight and I've folded to a few re-raises with marginal hands.  I haven't done anything out of the ordinary, partly because for the last hour I had gotten nothing but crap and also because I don't have a ton of live experience and my hands tend to shake like a drunk with the tremors when the action gets big.  But I digress…

Guy to my left, who won the tournament last weekend limps in and I call.  Both blinds call.

Flop comes down ATJ, 2 spades.

Blinds check and the open limper  bets 1500.  He started the hand with about 10-12 BB.

I raise to 6000, blinds fold and villain re-raises me all in.  I call

Results don't really matter here, but I'm wondering if a shove really matters here.  It's probably for nothing more than another 3,000 chips and the way this guy has been playing, I don't have much doubt that he's calling here. 

Any problem with the limp pre-flop?  Or the raise?  I think this is standard but I did question whether I should have just shoved on the flop.  I felt like I wanted to induce action more than have the guy fold on the flop with a big raise.  If he is drawing to a flush, I've got one spade in my hand so I could be on the re-draw.

Thanks
