Entrenar Cálculo de Variantes cortas (II)

por Roberto Alvarez

En el artículo anterior Cómo entrenar el Cálculo de variantes cortas, expliqué mi sistema para calcular metódicamente todas las variantes posibles y resolver ejercicios artísticos de Mate en Dos Jugadas.  Aquí tienen 20 posiciones para entrenar. En la caja de diálogo encima del tablero, pueden elegir el mate a resolver.

Para ver la solución a cada ejercicio (sólo después de haberla encontrado por Uds. mismos!), deben hacer click sobre “1.?” en la parte derecha al tablero, y allí aparecerá la solución oculta.

Recuerden: No hay mate en 2 jugadas que no pueda ser resuelto siguiendo un método de cálculo, sólo se necesita práctica!  Descargar ejercicios en formato PDF :
