Late in 6 max Tourney - Risk clash with big stack?

[CorvusMonedula]

About 19 players left out of starting 1088. I'm 2nd or 3rd in chips, having been in the top 20 pretty much throughout the whole tourney. The top 4 stacks are well ahead of the field.

Button has been playing tight recently or has not been catching any cards. I rate him as one of the better players left in the tourney. We're currently 4 handed at this table.
