The real development of the debut began around the 30s, mainly due to the efforts of the Soviet master Anatoly Gavrilovich Ufimtsev. In his games, played over several decades, and analysis, A. Ufimtsev introduced many interesting ideas into the system, which rightfully got his name. And now the Ufimtsev defense has grown into an independent debut, standing on the one level with such well-known defenses as the Sicilian, French defenses, the defense of Alekhine or Karo-Kann. What explains the great popularity of Ufimtsev’s defense? Of course, it is attractive that it has not yet been studied as many others. In addition, this construction allows you to create dynamic positions in which the advantage of White’s first move is minimized. Designed for highly skilled chess players.
