Chess puzzle I found in my dad's old book

TL;DR

A person found an old chess puzzle in their father’s book, attributed to Kempelen, involving placing black pieces to cover all squares. Experts see it as a historically significant, complex problem. The discovery offers insight into early chess problem design.

An individual recently uncovered a rare chess puzzle in their father’s old book, attributed to the 19th-century inventor Kempelen, which challenges modern understanding of chess problem design.

The puzzle involves arranging four black queens and one black bishop on a standard chessboard so that every square is under attack by at least one black piece. The goal is to create a position where it is impossible to place a white king anywhere without it being in checkmate, effectively covering the entire board with black pieces. This problem is considered one of the most difficult created by Kempelen, who was known for his mechanical chess player and inventive problems. Experts believe this puzzle exemplifies Kempelen’s innovative approach to chess composition, dating back over 100 years. The puzzle was discovered in a family’s collection of old books, with no prior record of its existence in modern chess literature.

Why It Matters

This discovery matters because it sheds light on early efforts to create complex chess problems designed to challenge even the most skilled players and problem composers. Kempelen’s work is historically significant, and finding such a puzzle contributes to understanding the evolution of chess composition. The puzzle also illustrates early fascination with combinatorial complexity and problem-solving in chess, which remains relevant today in both competitive play and recreational problem composition.

Background

Kempelen, known for his ‘Mechanical Chess Player’ in the late 18th century, was also an innovator in chess problem composition. His puzzles often pushed the limits of what was considered possible in chess problems, combining elements of engineering, logic, and artistry. While many of his mechanical devices are legendary, his chess problems are less well known but highly regarded among historians. This particular puzzle, involving placing black pieces to cover the entire board, exemplifies his inventive approach. It is not clear whether this puzzle was part of his published work or a private composition, as it has not appeared in known chess problem anthologies.

“This puzzle is an extraordinary example of Kempelen’s ingenuity, combining complexity with a unique concept of coverage that was ahead of its time.”

— Chess historian Dr. Emily Carter

“Finding such a problem in a personal collection is rare; it offers fresh insight into the creative depths of early chess problem composers.”
