Played in my first MTT on Stars yesterday and was generally pleased with the way I played. No, it wasn't the "big one",

just the $2 MTT at 6:30pm.
This situation came up at Level VI (100/200). Up to this point I had been playing very tight. I was able to take advantage when getting decent cards came but continuously saw my stack go down as I folded trash hand after trash hand (I know, just the normal types of hands for everyone).
I just got moved to another table about three hands earlier, so I don't have much of a read on anyone at this point. I am UTG when this comes up; (I am o_s_f)
Table '3535140 108' Seat #8 is the button

It goes without saying that I really screwed things up, but I would like to know what a sound approach would have been.
At this point we are down to about 620 players from a field of over 2100.
Average stack is about $4800.
The crazy people are mostly gone by now and play has been tightening up a little.
Thanks for any insight you can provide, I would like to hear from others before posting the disaster that this hand became.
Cheers
