Final Table...what's your move?

[nfpceo]

The following hand came up at the final table of a $10 + $1 NL tourney on Party. 10th place gets a $213 profit, 9th gets around $320 and so on. 1st is a huge $4,700 while 4th is around $1,200. I'm posting the pay outs because I want to see how much you factor them in to the decison you have to make on the below hand when you look at the other chips stacks. After I get some replys I will tell you what I did and the results of the hand.
