La mejor para trabajar pgns

Pero me gustaría que el tablero ,los colores,y sobretodo el fondo ese verde anti relajante se pudiese cambiar. En todo lo demás, perfecto. Enhorabuena a los desarrolladores

Poder meter variantes y anotaciones en las partidas es fantástico. Muy útil como tablero electrónico para leer libros de ajedrez.
