Oleg Pervakov (born in 1960 in the city of Kirov) is widely recognized as Russia's greatest living chess composer. He has composed nearly 500 studies and he has won the individual chess composition world championship three times: in 2004-2006, 2007-2009 and 2013-2015. In this book, Sergei Tkachenko, a member of the Ukrainian team that won the 5th World Chess Composition Tournament in 1997 and which came second in 2000, 2004, 2013, and 2017, has selected 100 of Oleg Pervakov's best studies. The selection is quite varied - from elegant short studies with six moves to romantic grotesques with many pieces on board and over 30 moves to the solution. Yet what all of these studies have in common is spectacular play by both sides. And watch out: they are tough! That said, Oleg's compositions are never boring. You may buy this collection of studies to test your endgame tactical abilities, to improve your endgame understanding, or simply to appreciate chess in all its beauty. Unlike previous studies books compiled by Sergei Tkachenko this book is not pocket-sized due to its longer solutions.
