45 man turbos

[jme1222]

The 45 man turbos seem to be my best game because I guess I'm good at being a push bot. The following hand is an example of the types of situations I feel I'm losing chips in:
PokerStars No-Limit Hold'em Tourney, Big Blind is t200 (6 handed) Hand History Converter Tool from FlopTurnRiver.com (Format: 2+2 Forums)

CO (t1730)
Button (t8625)
SB (t2930)
jme1222 (t3605)
UTG (t2495)
MP (t1070)

Preflop: jme1222 is BB with J[img]/images/graemlins/club.gif[/img], 8[img]/images/graemlins/diamond.gif[/img].

Final Pot: t3660

Results in white below: <font color="#FFFFFF">
jme1222 has Jc 8d (one pair, jacks).
CO has Kd Kc (three of a kind, kings).
Outcome: CO wins t3660. </font>

I'm guessing his range is FD, OESD, Qx, Jx?, underpair.... is 2-1 good enough for 1/3rd of my stack? I don't do pokerstove yet. Your thoughts are appreciated!
