Andersson is a very solid positional player. He draws a high percentage of his games against fellow grandmasters. He is renowned as a great player of endgames, especially rook endgames, and is famous for winning seemingly "unwinnable" endgames, often in very long games. Chess writer Dennis Monokroussos once remarked of Andersson's style, "For most of us, if we're playing a peer and major exchanges occur, a quick draw is the likely result ... for Andersson ... exchanges [are] often not the prelude to a quick draw but the signal that it [is] time for his opponent to start suffering." 1 In chess, the endgame (or end game or ending) refers to the stage of the game when there are few pieces left on the board. ...

Very few players in history have been as successful as Andersson at both forms of chess. Correspondence chess is chess played by various forms of long-distance correspondence, usually through a correspondence chess server, through e-mail or by the postal system; less common methods which have been employed include fax and homing pigeon. ...
