had a very hard time w/ this one. We were in the top 170ish of 2000 entrants at the time of this hand in the nightly $0.50 tournament. Villain has shown down KQ on the button and 77 in MP since I joined the table.

Initially, i thought this might be a tough fold, but you are almost 50% against a tight UTG range (99+;AQs+;AQo+),
so with 13BBs and over 2k in the pot this is a shove.
