Making a Fair Deal

This came up in a tournament home game I was playing in recently. For the sake of simplicity, I am going to round out the numbers.

Anyways...Two players go heads up late in a tournament. The next person to be knocked out does not make the final table and is OUT of the money.

Player #1, who is short stacked ($20) gets dealt pocket Queens. Player #2, who is the chip leader, gets dealt pocket Kings.

Player #1 acts first and goes all-in.
Player #2 calls.
Everyone else folds.

Before the board is dealt, player #2 offers a deal to P1. He says to P1, "I am an 8-2 favorite to win this hand. You only have a 20% chance to double up and win $40, but you also have an 80% chance to bust out. Give me $12 right now, keep $8 for yourself, and we will move on to the next hand."

There was some argument from among the other players on whether this was a good deal on a mathematical level. P2 argued that since P1 only had a 20% chance to win $, that means his equity, or break even point was only $8. Someone else argued that since P1 was only a 4:1 underdog, his share of the $40 pot was $10.

At this point, everyone was confused.

Who is right? What would have been a "fair deal" for P1?

4 to 1 = 1/5, not 1/4...I believe therein lies the confusion. With a $40 pot, a $30/$10 split is 3:1.

Actually, there wasn't that much confusion with the 4:1 comment. Most of us knew right off the spot that 4:1 isn't the same as 1/4. All his comment did was muddle everyone's head with more numbers.

But is the deal that P2 proposed correct? Did it make mathematical sense?

This is wrong...and would be correct if the odds are 3:1.

P2's reasoning seems correct. He's taking $32 out of the pot and the other player is taking $8 out of the pot, which is a 4:1 split.

Did the other players fail to realize that this is costing them money, and that it is against the rules??

Great question. Nobody seemed annoyed [at this friendly home game] about the idea of these players making a deal.

Before anyone had a chance to speak up against it, the player with Queens rejected the deal and went for his long-shot.

Result: He lost and busted out.
