$6.5 bubble with two microstacks what to do??

[malnek]

PokerStars Tournament, Big Blind is t400 with t25 antes (4 handed) Converter on pregopoker.com

CO (t715)
malnek (t885)
SB (t2445)
BB (t9455)

Preflop: Hero is in Button with K[img]/images/graemlins/heart.gif[/img] 5[img]/images/graemlins/heart.gif[/img]
<font color="red">CO raises to t690 (All-in)</font>, <font color="red">malnek raises to t860 (All-in)</font>

assuming that co is pushing just about anything and also assuming that sb and or bb calls with any 2 was my shove here correct? sngpt gives me a fold but intuitively this shove makes sense for me.

the reasoning being that if CO wins and i fold, im probably gonna bubble.

if CO loses and i fold i money into third and invariably finish third.

if CO loses and i call and lose to either SB or BB i finish third.

If CO loses and i call and i win, i can make a run at 2nd or 1st?
