need help finding the subgame perfect equilibrium in the pirates treasure game. It is a game theory game. The game includes 5 pirates who find 100 gold coins. Pirate one is the leader. He proposes a split of the coins among the pirates and everyone votes and ties are in favor of the proposer. If the vote passes the game ends. If vote is rejected, the proposer is thrown overboard and the process repeats with pirate 2 as leader who will propose new split if rejected he is thrown overboard and process repeats.
