Very interesting post. But, Fischer have not losing with Bxh2. This was not the losing move. Kind Regards, Eduard (german: dennoch, es würde mich brennend interessieren ob Fischer das Läufer- opfer wirklich einkalkuliert hat. Das wird er aber niemals verraten. Ich habe als Kind das gesamte Match damals live über Radio verfolgt - es wurden ständig neue Züge durchgegeben wie das jetzt im Internet geschieht - und ich weiss dass es gleich die erste Partie war.. oh wie bitter damals für einen Fischer-Fan :-)
