Os softwares de xadrez não conseguem resolver esse problema. Prove que você é melhor que eles: as Brancas jogam e dão xeque-mate em 37 lances! [Dica: todos os 37 movimentos das Brancas são do Rei!]

You are a closet sadist, Paulo Cezar Filho.
ResponderExcluirThat's not true, Jacob Hoover. I even give hints to make the reader's task easier. :)
ExcluirOK. Let's give this a shot...
ResponderExcluirI just worked out a sequence that is similar to the Loyd 53-mover, but it's too long (49 moves). Is there a shorter way to achieve the same result?

ExcluirI actually looked up the solution, but I waited until I understood the solution before deciding to post it here.
ResponderExcluirThis is very similar to Sam Loyd's 53-mover, in that White must force all the black pawns to move forward before he can mate. White loses a tempo several times during this sequence; these tempo-losses are marked with asterisks(*).

ExcluirMove 36 has a typo. It should be 36 Ke1 Bf2+.
