that they are P1 and P2, and P2 is fierce. The best solution of P2 is of course: He had 100 gold coins and P1 had 0 gold coins. His vote is enough for 50%.
Take a step forward. Now add a more fierce pirate P3. P1 knows -- P3 knows that he knows -- if the P3 scheme is rejected, the game will only continue from P1 and P2, and P1 won't get a gold coin. So P3 knows that as long as P1 is given a little sweetness, P1 will agree with his plan (of course, if P1 is not given a sweetness, nothing will be
