The most celebrated attacking game of the 19th century. Anderssen sacrifices one knight, two rooks, and his queen to force checkmate with just two bishops and a knight. Named by Ernst Falkbeer, who published it in La Régence as "die unsterbliche Partie."
Fischer, an almost exclusive 1.e4 player, played 1.d4. The resulting positional masterpiece combined Capablanca-level strategic clarity with Fischer's meticulous preparation. When Fischer played his key pawn advance on move 25, Spassky stood up and applauded — then resigned on move 41.
Boris Spassky, still at the board after playing his 41st move and seeing Fischer's reply, stood up and led the audience in applause for his opponent before shaking hands to resign. A gesture unique in World Championship history — and one of the most sportsmanlike moments in any sport.
Voted the greatest chess game of the 20th century in multiple polls. Kasparov plays a rook sacrifice on move 24 (Rxd4!!) that initiates a king-hunt lasting 16 moves, pursued with machine-like accuracy yet under tournament conditions with no computer assistance. The final position after 44.Qa4+ Kb1 45.Qxa7 cannot be reached without seeing the entire cascade from move 24.

The Elo rating system, designed by Hungarian-American physics professor Arpad Elo and adopted by FIDE in 1970, is the mathematical backbone of chess ranking — later adopted by sports, video games, and competitive fields worldwide. New Rating = Old Rating + K × (Actual Score − Expected Score), where K is a volatility factor and Expected Score is calculated from the rating difference between players.
