Typische Opfer: je 5x Lxh7+ und TxSf6

By Michael Scheidl Date 2011-04-26 04:49

Es gibt typische Opferzüge (bzw. Scheinopfer wenn man so will, je nach Definition und Sprachgebrauch), die man relativ häufig antrifft, wobei die umgebende Stellung im Detail oder auch weitgehend verschieden ist. Zwei davon sind das Läuferopfer auf h7 sowie das Qualitätsopfer auf f6 (f3), wobei dort natürlich meist ein Springer geschlagen wird. Ich habe je fünf Beispiele aus diversen Computerturnieren herausgesucht, die manchmal mehr, manchmal weniger "klassischen" Charakter aufweisen.

Es ist eher zur menschlichen Unterhaltung gedacht. Für heutige Engines und Computer ist der Schwierigkeitsgrad vorwiegend gering. Am längsten dürften sie an der Nr. 5 zu knabbern haben (mein PC mit P4/2,4 GHz gehört aber sicherlich zu den langsamsten die noch in Gebrauch sind):
