currently 18 bets and 5 players in the pot. If we make these assumptions:

a) 4players have an ace.
b) no players have a 6.
c) 5th player is going to fold
d) we can get one player with an ace to fold if we raise

Then we gain 18/3 - 18/4 or 5.6-4.5 = 1.1BB with a raise.

Sadly, all these assumptions are not always true. UTG has a 6 often. Random other player has a 6 sometimes. The guy with the ace we're trying to fold doesn't fold. I'm pretty sure this is a call.
