I don't get it. Wouldn't the most equitable thing have been for each to go their separate ways after they got this thing into gear? Why would Kane want to be paid anything by Nestor, and why would Nestor agree to pay him anything?
Kane chose to run his mouth off about the play to Nestor, and we're told Nestor "figured out" double up was the key? That was the easiest part, and a caveman could have figured it out after they played it a few times. The key is the bill feeder working before the hand is really over. Then there's this taxes issue. Why involve something like that when they expected the big money to just keep rolling in?
If anything, these guys are a classic study in not understanding human stupidity.
