In the 19th century, blind individuals aspired to participate in intellectual games like chess. While specialized tactile chessboards emerged later, Louis Braille's development of the raised-dot writing system in 1824 was a pivotal step in making information accessible to the blind, including the game of chess. The world's first official chess tournament for blind players was held in 1938 in the Soviet Union, organized by the All-Russian Society of the Blind. Already at that time, players used special boards with indented squares and tactile pieces: black pieces with spikes and white pieces smooth to the touch. Since then, chess has become one of the most important intellectual disciplines for people with visual impairments. The idea of using tactile chessboards with indented squares and distinguishable pieces by touch was implemented in the mid-20th century and became an international standard thanks to the efforts of the International Braille Chess Association (IBCA). Today, major international tournaments and championships for blind chess players are regularly organized by the International Braille Chess Association (IBCA). Among blind chess players, there are International Masters and even Grandmasters. For example, Grandmaster Marcin Tazbir from Poland is one of the strongest players in the world. How do blind players compete? • They use specially adapted tactile boards with locking mechanisms for the pieces. • Players announce their moves aloud for accuracy and recordkeeping. • In matches against sighted opponents, two synchronized boards are used — one tactile, one regular. Blind chess shows that intelligence and strategy can go far beyond sight.

🔹 Detailed Story and Background 🗓 Historical Period: Early Middle Ages (~7th–9th century CE) 📍 Region: Persia (modern-day Iran), later expanded to Arabic-speaking regions and Europe 🔠 Origin of the Term: The term "checkmate" comes from the Persian phrase "Shāh Māt" (شاه مات). • "Shāh" means "king" in Persian. • "Māt" does not literally mean "dead" but rather "helpless," "defeated," or "powerless." Thus, the phrase "Shāh Māt" translates more accurately to "the king is helpless" or "the king is checkmated", not necessarily "the king is dead" (a common but imprecise interpretation). ________________________________________ 🧭 Linguistic and Historical Journey: • The game of chess evolved from Chaturanga, an Indian board game, and was later adopted and modified by the Persians as Shatranj. • As the game spread across the Islamic world and into Europe, many terms were borrowed or adapted linguistically: o From Persian to Arabic o From Arabic to Latin o From Latin into Old French → Modern English • The word "checkmate" in English is derived from this linguistic journey. ________________________________________ 🎓 Linguistic Insight: • The Persian word "māt" is rooted in a verb meaning "to be defeated" or "to remain still", not directly "to die." • This subtle distinction gives the phrase a symbolic and poetic power: it's not that the king is slain, but that he can no longer act — his options are gone. ________________________________________ 📝 Why It Matters: • This phrase is one of the most iconic endings in any game, and it reflects chess's deep historical and cultural layers. • Understanding its true origin helps connect chess not just to logic and tactics — but to language, poetry, and the ancient world. 📚 Sources & References: 1.
