Moulinet (échecs)
# Moulinet (échecs)

Le moulinet (ou la moulinette) est une manœuvre tactique aux échecs dans laquelle une série d'attaques à la découverte, généralement commises à l'aide d'un fou et d'une tour, permet un gain de matériel parfois très important.

Un exemple célèbre de cette manœuvre a été joué par Carlos Torre contre l'ancien champion du monde Emanuel Lasker au tournoi de Moscou en 1925. On retrouve aussi cette manœuvre dans la partie du siècle remportée par Bobby Fischer alors âgé de treize ans.

## Principe

Dans la position du diagramme, les blancs jouent 1. Txg7+ forçant le roi noir à se déplacer sur la diagonale contrôlée par le fou blanc 1... Rh8. Grâce aux échecs à la découverte, la tour blanche peut alors effectuer un mouvement de va-et-vient entre la case g7 et chacune des cases de la septième rangée, le roi noir restant confiné aux cases g8 et h8 : 2. Txf7+ Rg8 3. Tg7+ Rh8 4. Txd7+ Rg8 5. Tg7+ Rh8 6. Txc7+ Rg8 7. Tg7+ Rh8 8. Txb7+ Rg8 9. Tg7+ Rh8 10. Txa7+ (Grâce à cette manœuvre, toutes les pièces noires de la septième rangée ont disparu) 10... Rg8 11. Txa8 et les noirs sont perdus.
