Solutions to last week's puzzles
By GM Lubomir Kavalek
Both writers simply left out the fact that you can promote a pawn into a queen,
rook, bishop or knight of the same color only. They also didn't mention that
you can't promote your pawn into a King. Renzo Moran discovered all three solutions.
Congratulations! You find the solutions after each diagram.
In 1853, a French aristocrat, Barthelemy de Basterot (1800-1887) published
in Paris Traite elementaire du jeu des echecs (Elementary Treatise
on the Rules of Chess), which included chapters on chess history and literature.
Basterot was a strong player, but treated the essential rules rather loosely.
For example on pawn promotion he wrote that any pawn reaching the eighth (or
last) rank can be changed to any piece a player chooses. The player, he said,
was only required to announce what piece it was.
No wonder he became the target of one of the most gifted chess composers, Leonid
Kubbel, who created two problems based on Basterot's rules. Both two-movers
are playful jokes and the clue lies in what Basterot's definition did not forbid.
Here is the first one:
Leonid Kubbel
White mates in two moves
Solution: 1.e8 black king (!!) Kd8 2.Qd7 mates
both black kings
Kubbel was not the only one laughing at Basterot's foolishness. I have added
a three-mover by the brilliant Czech problemist Emil Palkoska that fits the
bill as well.
Emil Palkoska

White mates in three moves
Solution: 1.d8 white king (!!) Kc6 2.Rb2 Kd6 3.Rb6 mate;
or 1...Ke6 2.Rf2 Kd6 3.Rf6 mate
Even some great modern chess writers like the Australian Cecil J.S. Purdy,
the first world chess correspondence champion, can overlook some essentials.
For example, in explaining the limitation to castling, he is silent about castling
into a check. On pawn-promotion, he specifies that a pawn, on reaching the farthest
row, can become a queen, rook, bishop, or knight, but not a king. What did he
miss? The answer is hidden in Kubbel's second composition.
Leonid Kubbel
White mates in two moves
Solution: 1.b8 black bishop (!!) Bh2 2.Qc8 mate; or 1...b5
2. Qxb5 mate
Olivier Pucher from Metz, France, suggested: "1.b7-b8 black bishop is
probably the intention, but the way Purdy's rules for promotion are reported,
it is not so clear if 1.b7-b8 black pawn would be illegal..." It would
allow after 1...b7 or 1...b5 only one mate with the white queen on the square
b5. Since Purdy didn't mention that a pawn reaching the last row can stay a
pawn (white or black) or that you can have your own pawn on your first rank,
it could be considered slightly illegal. But, hey, who are we to argue with
a creative Frenchman?
