Faites vous la main – Leçons vidéos et Cours d'échecs

Dans les positions ci-dessous vous aurez l’occasion de travailler la maitrise de l’opposition à travers quelques transpositions encore relativement simples.

N’oubliez pas que dans les transpositions c’est maintenant ou jamais de transposer dans une finale dont on connait le résultat, soit pour une nulle soit pour un gain.

N’oubliez pas non plus l’importance du calcul. N’allez pas trop vite chercher la solution, ne touchez rien et essayez de résoudre la position de tête.
