(I’m not making this one ungooglable but the standard version has enough differences that you’ll be wrong if you cheat! Also we’ll murder you. Don’t laugh, we’ve done it before!)
A bunch of pirates have stolen a treasure chest full of gold and they decide to divvy it up as follows:
The shortest pirate proposes an allocation and they all vote on it (including the proposer). If the proposed allocation passes the vote they go with it. If not – or even if there’s a tie – they heave the shortest pirate overboard and start over with the new shortest pirate.
Assume that when they kill the short person they feel a tinge of remorse, but they’ll gladly kill them if they stand to gain so much as a doubloon by it.
So if you’re the shortest pirate what allocation should you propose?
