Do I get involved in this?

[bkm]

Party Poker No-Limit Hold'em Tourney, Big Blind is t300 (4 handed) converter

Hero (t1513)
UTG (t4430)
Button (t942)
SB (t1115)

Preflop: Hero is BB with 9[img]/images/graemlins/spade.gif[/img], T[img]/images/graemlins/spade.gif[/img].
<font color="#666666">1 fold</font>, <font color="#CC3333">Button raises to t942 (All-In)</font>, SB calls t792, Hero ????


If I fold:
SB wins - I'm ITM
Button wins - SB is left with t173 and will probably be blinded out.

If I do decide to get involved and get SB to put the rest of his chips in pre or post flop.
I win - I'm guaranteed at least 2nd and am heads up with UTG with nearly equal stacks.
SB wins - I'm ITM but have &lt;2xBB
Button wins main &amp; SB wins side - I'm out in 4th.
Button wins main &amp; I win side - I'm ITM but have &lt;2.5xBB
