(M. Velucchi). MWa: "Da es mit dem wS nicht gelingt, den sS nach b6(c7) zu zwingen, muß eine stärkere Figur her: 1.g:f3 L:d6 2.f4 La3 3.Sd6 (wichtig, um den sL wieder auf die glq richtige grq Diagonale zu bringen und Feld f8 zu sichern!) L:d6 4.f5 Lh2 5.f6 Lb8 6.f7 Lh2 7.f8 ,D Sd8 8.Df5 Se6 9.Df7 (hier wurde mir der Sinn des sBb5 klar) Lb8 10.Dc7 S:c7#". "The best work I have ever seen by Velucchi", meint LV.
