Aqui está um problema difícil até para alguns softwares de xadrez: as Brancas jogam e vencem - na verdade, dão xeque-mate em 11 lances!
(Here is a hard problem even for some chess softwares: White to play and win - in fact, give checkmate in 11 moves!)

Observação: o nome deste compositor letão é Jānis Bētiņš, mas ele é chamado de Johann Behting pela maioria das fontes.
(Note: the name of this Latvian composer is Jānis Bētiņš, but it is spelled as Johann Behting by most sources.)
PCFilho
Level: very hard. 🌟🌟🌟🌟🌟
ResponderExcluirIndeed, it is a very hard problem.
ExcluirI gave it to the world-famous Stockfish, and after 5 minutes running in my CPU, it didn't find the solution.
(However, other chess softwares did solve it.)
A hint, please?
ExcluirHints:
Excluir- the key is a King move;
- never let the black King arrive at the e-column.
Oh, something important:
ExcluirHappy birthday, Jake!!! 🎂
Thanks for the birthday wishes, Paulo.
ExcluirNow to the task at hand.
Here is the solution, which took Popeye the better part of an hour on my piece-of-crap laptop:
1 Kd3! (waiting)
1 ... g3 2 f4 Kf1 3 Kd2+ Kg1 4 Bd7 Kf1 5 Bh3 Rg1 6 Bg4 Rh1 7 Be2+ Kg1 8 Sc3 Kf2 9 Se4+ Kg1 10 Sg5 Kf2 11 Sh3#
1 ... Kf1 2 Kd2+ Kg1 3 f4 g3 transposes to the above line.
Well done, Jake!!
ExcluirIt seems Johann Behting came from the last century to bring trouble to our brains (both Carbon and Silicon brains).
