Live MTT, 2 tables remaining with large blind to stack ratio:

[xileh]

Last night I played in my first live MTT. With about 16 or 15 people remaining and top 7 paying, everybody at the table had between 7-20 thousand chips with the blinds at 1000-2000.

My stack is at 15000

It is announced that for the next hand, blinds will be raised to 2000-4000. UTG+1, who just joined the table, pushes all-in with 14700. I look down and see 77 in UTG+2. What is my action? I'll post my action and results later.
