Preflop: Hero is UTG+2 with A♣K♣
1 fold, UTG+1 pushes t6045 (11+), Hero?

Opponent calling ranges when hero pushes:
UTG+3 (9.1+), UTG+4 (1.8+), UTG+5 (8.1+), CO (4.6+), BTN (2.6+), SB (8+), BB (10+)

I was amazed when SnG wiz brought this up as a fold.

I put the nash in: http://www.holdemresources.net/h/web-calculators/nashicm/results.html?action=calculate&bb=300&sb=600&ante=60&structure=0.36%2C0.23%2C0.165%2C0.115%2C0.085&s1=3914&s2=6045&s3=6300&s4=1145&s5=9769&s6=1590&s7=3240&s8=7232&s9=2890&s10=2805

AKs is the bottom of my pushing range and it relys on very tight folds from the rest of the players.
