the risk is moderate, the reward is ample. (plus)
you have the big stack and can't be eliminated. (plus)
Your pot odds dictate a 33% chance is needed to win this pot. Plus the added equity of eliminating 3 players if you win. (plus)
Given the stack sizes and reasonable ranges (say 77+, A9s+, KTs+, QTs+, ATo+, KQo or thereabouts to keep it simple) we can infer that we have about 30% equity with our AK. (plus)
So if you add all the +'s and our equity it is about even to call here. But it is by no means a landslide fist pump call.
Except when we do actually fistpump call.
