To raise or not to raise....

[Aces_up07]

I know this is a tourney hand, but I thought posting it here would be ok, since my question has nothing to do with the fact that im in a tourney.


Party Poker Limit Hold'em Tourney, Big Blind t200 (9 handed) converter

MP2 (t7943)
MP3 (t3330)
CO (t80)
Button (t8075)
SB (t5455)
BB (t7668)
UTG (t6207)
Hero (t1104)
MP1 (t955)

Preflop: Hero is UTG+1 with K[img]/images/graemlins/spade.gif[/img], A[img]/images/graemlins/club.gif[/img].
UTG calls, <font color="#CC3333">Hero raises</font>, <font color="#666666">4 folds</font>, Button calls, SB calls, <font color="#666666">1 fold</font>, UTG calls.

Flop: (9 SB, t1800) 4[img]/images/graemlins/club.gif[/img], K[img]/images/graemlins/heart.gif[/img], 4[img]/images/graemlins/diamond.gif[/img] <font color="#0000FF">(4 players)</font>
SB checks, <font color="#CC3333">UTG bets</font>, hero...

Should I not raise here? Since I am either way ahead or way behind, I figured I could just let button and SB get in cheap if they want. That way if I am way behind, I save myself a bet or two and if I am way ahead I can gain myself some bets through the overcalls. Is that logical?
