3 make the $ with 5 players left. Blinds 1500/3000

UTG: 32,000
CO: 18,000
BTN: 42,000
SB (Hero): 42,000
BB: 33,000

BTN shoves and I call in SB with AKo. Pretty sure this is a bad call considering the ICM pressure that can still be applied to the other players. However, Villain was shoving around %50 in this spot and I thought I should take the high equity spot while i have it. This spot left me scratching my head and I'm pretty sure i need to buy a solver and start practicing with it because i really didn't know what to do. In hindsight I think it is a terrible call considering the Satellite format where 3 pay an equal amount ($109 tourney entry).
