Este retroceso del caballo es aún un terreno inexplorado con menos teoría, tal vez algo que los jugadores necesiten contra la gran teórica Najdorf. Veamos algunas ideas de 6.Cb3. 1.Está dirigida principalmente contra los esquemas Boleslavsky que surgen con ...e5 porque se ganaría un tiempo jugando Ag5 con lo que se elimina un caballo defensor de d5. Es cierto que el Cb3 está más retirado del centro que en d4, pero esto dificulta al negro su ruptura central ...e5. 2.Otra importante idea del blanco es preparar el ataque Keres si el negro juega ...e6.
