Fred Davies: Good question. I think that Kupchik's 53.Ra7+? was a losing mistake and e.g.53.Be2 would still have drawn.

Dear Grandmaster

Always enjoy your expert series on difficult chess endings. Particularly the ones where you debate with the readers whether an ending was drawn or lost. Here is one for you. Take a look at A Kupchik v FJ Marshall New York 1915. In his book, My Best Games of Chess, Marshall claims that the sacrifice of a minor piece was justified in order to reach a won ending. But some of the silicon monsters appear to disagree. Who is right?

Sincerely yours

Fred Davies

Frits Fritschy: Yes I should have given 48.fxg4 Ke5 49.Nd3+ Kd5 50.Nf2 Kc4 51.Kd2 Kb3 52.Kc1 Bf1 53.Kb1 Kc4 54.Kc2 Kd4 55.Kd2 Bc4 and Black wins sooner or later using zugzwang again and again.

You left us with a nice (but not overly difficult) puzzle how black wins after 48... fxg4.
