Good, bad, ugly? (Slowplaying pocket kings)

[Mr. D]

What do you all think of slowplaying pocket kings on the button towards the middle of a SnG ($22 party)? I did, with the intention of pushing if no ace flopped and it cost me my stack on account of someone hitting trips. I'm not quite sure what I was thinking (well, actually I was thinking I read that this is a good play in the Reuben/Ciaffone Big-Bet book.. but loosely applied book knowledge is just trouble) and I expect I'll get berated for this one. Anyways, I'm wondering if there is any merit to this play? Maybe as a Stop and go? Here's the hand:

Party Poker No-Limit Hold'em Tourney, Big Blind is t50 (6 handed)

SB (t1175)
BB (t600)
UTG (t3635)
MP (t1495)
CO (t345)
Hero (t750)

Preflop: Hero is Button with K[img]/images/graemlins/diamond.gif[/img], K[img]/images/graemlins/spade.gif[/img].
UTG folds, MP folds, CO calls t50, Hero calls t50, SB completes, BB checks.
