Party 30+3... SB very late in tourney

[tradingman123]

I have not played many of these MTTs and this is the first time that I have made it this far. Anyways, hero is SB with ~ 50k in chips with 14 players left of 1200 person tourney. Blinds are 4k/8k.

All fold to Button, who is pretty aggressive. Button open pushes for 49k. Hero holds 66. Hero?

Thanks for your thoughts.
