*** Black to play and checkmate ***


An embarrassing situation for the white king. It seems that black should invest some extra time to force checkmate, but the truth is that the checkmate net is already set, it just has to be found. Meanwhile, White dreams of pestering with moves like Dg6, but he's lost.

*** Juegan negras y dan mate ***


Una situación embarazosa para el rey blanco. Pareciera que las negras deberían invertir algunos tiempos extra para forzar el jaque mate, pero lo cierto es que la red de mate ya está tendida, sólo hay que hallarla. Mientras tanto, las blancas sueñan con molestar con jugadas como Dg6, pero están perdidas.

Excellent! You found the non-evident move Nb1.

Yes it was a very unusual move. The ♘ was almost out of the box.

Hi @gingerbyna Knight cannot move to “b1” did you mean “n1”?

Hello @rodrook in algebraic notation there is no "n", the board only has a,b,..., to h, and of course 1, 2, ..., to 8.

In the older notation though, there is "N" in the form N1, ..., N8, and it's capitalized and so in this example it would have been

  1. ...N-N8 (or 2. ...N-QN8)

and not N1 or "n1" (which is the wrong way to write it) as the black pawns are moving upwards

Thanks for replying @gingerbyna. As I attempted to animate your solution I made the mistake of thinking b1 was bishop1 from the old descriptive notation that I used for many years, it similar to the mistakes I make in my tournament play now. :) gAnimatio.gif

This animation is only your main line solution.
