Basic setup is PS $2+0.20 tourney and we've reached the bottom end of the money. I've been tight passive for the past two rounds of blinds b/c i've been cold-decked and talking on the phone. The table usually has limpers and minimum raisers pre-flop.

I'm dealt KQs in the BB w/ 5 callers including the SB. I have ~T20000 (the avg stack is about ~T17000) and push all in into a T6600 pot. My thinking is that it's time to move to make the decent money and I was 99% sure no one had a hand that would dominate mine. How was this move?

Thanks
