Mikhail Nekhemyevich Tal was a Soviet and Latvian chess player and the eighth World Chess Champion. He is considered a creative genius and is widely regarded as one of the most influential players in chess history. Tal played in an attacking and daring combinatorial style. His play was known above all for improvisation and unpredictability. Vladislav Zubok said of him, "Every game for him was as inimitable and invaluable as a poem". His nickname was "Misha", a diminutive for Mikhail, and he earned the nickname "The Magician from Riga". Both The Mammoth Book of the World's Greatest Chess Games and Modern Chess Brilliancies include more games by Tal than any other player. He also held the record for the longest unbeaten streak in competitive chess history with 95 games between 23 October 1973 and 16 October 1974, until Ding Liren's streak of 100 games between 9 August 2017 and 11 November 2018. In addition, Tal was a highly regarded chess writer. Tal died on 28 June 1992 in Moscow, Russia. The Mikhail Tal Memorial chess tournament has been held in Moscow annually since 2006.
