=EGTB records= In October 2005, Marc Bourzutschky and Yakov Konoval announced that a position in the ending of a KRRNkrr requires 290 moves to convert to a simpler winning endgame. The old record was 243 moves from a position in a rook and knight versus two knights endgame, discovered by Lewis Stiller in 1991. In March 2006 the wizards of 7-men endgames, Marc Bourzutschky and Yakov Konoval found a 330 moves win in KQBNkqb and in May 2006 a 517 moves win in KQNkrbn.
