The brilliant chess move (48)

Post by Glarean »

.

The weekly series of chezz puzzles "The brilliant chess move" (Glarean Magazine) includes
tactical and strategic examples of great human chess art, and simultaneously
it is composed of very hard positions for most chess software.

The youngest member of this Hall of Fame is a shot by the Swiss IM
Richard Gerber, played against the Macedonian GM V. Georgiev (Lucerne 2003).

The 2d diagram is wrong, there should be a black pawn on f7. Unfortunately, I am not a FEN person.

That might explain why the computers could not solve the diagram? I could not find a 2003 game between Georgiev and Gerber, one in 2004 but it was won by Richard Gerber playing Black after a sac on h7 by Vladimir Georgiev that did not work out, it was a different game, played in Geneve 2004.

Debugging is twice as hard as writing the code in the first
place. Therefore, if you write the code as cleverly as possible, you
are, by definition, not smart enough to debug it.
