Quick Q about push late in MTT with very short stack.

[roamer590]

This is the $8+R on Stars, with around 1000 entrants.
Now we are down to 40 players.

Level is 3k/6k/600 so the pot has 14600 before I act.
Makes my "M" about 4.

I had been playing very tight on this table.
Should I puah or wait for better cards?
Should I maybe be supertight when this close to FT and thousands of $$?

Thank you very much for your opinions.
