Un Error En Los Programas De Ajedrez

En el siguiente diagrama, muestra una típica posición de bloqueo. Los programas de ajedrez tienen la dificultad de encontrar la solución...

Esta es la evaluación que los programas de ajedrez entregan: 

Juegan Negras Y Tablas... La Respuesta es: 1... ♜xh4! ; 2. ♔xh4 - ♝d4! 

Esto nos demuestra cómo la evaluación de los programas de ajedrez puede ser incorrecta en los finales o al menos no siempre confiable. Stockfish está evaluando esto materialmente como ganador para las Blancas, por lo que probablemente esté haciendo movimientos aleatorios de Rey para evitar un empate.

Posición tomada de la Partida:
Hans Ree - Vlastimil Hort, 1986
