$10 NLHE SNG on Stars. 4 left. Been that way since 25/50. It is now 100/200 with ante.

Here I play KQo from UTG for a raise to 4x BB and I die. Here is the nitty gritty.

Seat 2: jon_1van (2204 in chips)
Seat 5: ONE NEEDS (6544 in chips)
Seat 6: DollarStore (2514 in chips)
Seat 8: MissedTurn (2238 in chips)

ONE NEEDS: posts small blind 100
DollarStore: posts big blind 200

*** HOLE CARDS ***
Dealt to jon_1van [Kd Qc]
MissedTurn: folds
jon_1van: raises 600 to 800
ONE NEEDS: calls 700
DollarStore: folds
*** FLOP *** [6d Th Kc]
ONE NEEDS: checks
jon_1van: bets 1379 and is all-in
ONE NEEDS: calls 1379
*** TURN *** [6d Th Kc] [3c]
*** RIVER *** [6d Th Kc 3c] [4d]
*** SHOW DOWN ***
ONE NEEDS: shows [Kh Ah] (a pair of Kings)
jon_1van: shows [Kd Qc] (a pair of Kings - lower kicker)
ONE NEEDS collected 4658 from pot

Since it was 4 handed I figured KQo is good for a raise.

Is this dumb?

If you assume you raise this hand I can't imagine a difference in my play that would have changed the outcome.

For some reason I think that position could/should come into play when deciding how to best play this hand. If anyone has a few pointers about this I would greatly appreciate them.
