At a final table I have seen this done with TT+, AK.
However it is short handed which could mean his range could be this wide.
Although given that he has a big stack and he is going up against the only player who can knock him out I think it would be really foolish to do this with less than QQ+, AK.
However it really depends on how much you have been raising and how tight he is. If he expects you to open with a wide range then he may well do this with TT expecting you to fold a large majority of the time, also if a lot of raises are going to the flop then the same will apply.

To be honest though in general his range is well ahead of you so its a pot odds v. prize structure question. If you lose you are crippled and $500 is looking good if you fold you still have the ability to steal liberally and with 3 steals you will have more than made up for this.
