Mikhail Tal was a Soviet Latvian chess Grandmaster and the eighth World Chess Champion. Widely regarded as a creative genius and the best attacking player of all time, Tal played in a daring, combinatorial style. His play was known above all for improvisation and unpredictability. Every game, he once said, was as inimitable and invaluable as a poem. He was often called "Misha", a diminutive for Mikhail, and "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. In addition, Tal was a highly regarded chess writer. He also holds the records for both the first and second longest unbeaten streaks in competitive chess history. The Mikhail Tal Memorial has been held in Moscow annually since 2006 to honour Tal's memory.
