What % (roughly) of the time am I behind here?

[Gramps]

Party/Empire $215 NL SNG. If suits don't show up on this post (doesn't look like they are), it was a rainbow flop and flush draw out there on Turn. Only read I have is that MP1 is a bit loose/reckless, but not extremely so.

Party Poker No-Limit Hold'em Tourney, Big Blind is t15 (10 handed) converter

MP2 (t1070)
Hero (t1000)
CO (t1000)
Button (t990)
SB (t940)
BB (t1000)
UTG (t1000)
UTG+1 (t1000)
UTG+2 (t1000)
MP1 (t1000)

Preflop: Hero is MP3 with 8[img]/images/graemlins/heart.gif[/img], 8[img]/images/graemlins/spade.gif[/img].

I'm not much worried about BB - seems like a big bet for T9. MP1 and MP2 sure seem to like their hands, but a lot of players dont' play T9 in MP...but the betting action seems to say it's out there...

...what % of the time is T9 (or a slowplayed KK or JJ) out there do you think? Go to war or get the f--- out of the way?
