As Brancas jogam e dão xeque-mate em 2 lances!
(White to play and give checkmate in 2 moves!)
Este post é um tributo ao 159º aniversário de Walter Irving Kennard (03/12/1860 - 31/05/1936), um brilhante problemista de xadrez americano. De acordo com A. C. White e Kenneth Howard, ele costumava compor seus problemas sem usar um tabuleiro de xadrez. Sua magnum opus, na minha opinião, é este mate-em-4 publicado aqui em fevereiro de 2018.

In the diagram, the black king has two flights. The key 1 Qb8! (waiting) grants another two flights. Each of the four flights admits a pure mate:
ResponderExcluir1 ... Kc5 2 Qd6
1 ... Kc3 2 Qb2
1 ... Ke4 2 Qf4 (also a model)
1 ... Ke3 2 Qf4 (another model, distinct from the previous due to the black king being mated on a different square)
Another pure mate is seen in 1 ... S~ 2 Qe5 (and 1 ... Se5 2 Qxe5 is a third model).
Well done, Jake!
