The chess game between Friedrich Sämisch and Aron Nimzowitsch played in 1923 in Copenhagen is particularly noteworthy for being one of the iconic encounters that highlighted Nimzowitsch’s innovative and influential chess ideas.

In this game, Nimzowitsch, playing with the black pieces, introduced and demonstrated his groundbreaking concept of “overprotection” and “prophylaxis.” These concepts emphasized the importance of strengthening and defending key squares and pieces before launching an attack. Nimzowitsch’s play in this game showcased his deep understanding of positional play and his ability to create strategic imbalances.

One of the most famous moments in this game occurred when Nimzowitsch sacrificed a pawn to establish a powerful knight outpost on d5, a concept that became known as the “Nimzowitsch Blockade.” This strategic maneuver restricted Sämisch’s pieces and gave Nimzowitsch a long-term advantage.

While the game itself ended in a draw, it became famous for the innovative and prophetic ideas introduced by Nimzowitsch. His concepts of overprotection, prophylaxis, and the blockade had a profound impact on chess theory and strategy, influencing generations of chess players and shaping the evolution of the game.

Overall, the game between Sämisch and Nimzowitsch in 1923 is celebrated for its contribution to the development of modern chess theory and for showcasing Nimzowitsch’s visionary approach to the game.
