Les noirs jouent b5 et installent un cavalier en c4 sur une case très forte.

L’idée noire est de colmater la colonne « c » semi ouverte (pour les Blancs) en installant un Cavalier en c4 colmatant régulant ainsi toute initiative blanche sur l’aile Dame et bien évidemment en cas d’échange les Noirs se retrouveront avec un pion passé soutenu. La case c4 est de fait une case très forte !
