PART 2 • The chess tree Creating a tree based on a player's games is an incredibly useful tool for studying the games of great players. You can see at a glance how a player responded to various openings. For example, here's how Marshall's tree looks after the move 1.e4 is played: • We can see in an instant that Marshall was overwhelmingly an advocate of double King pawn openings when he had the Black pieces: he played 1...e5 more often than all other replies combined. • Creating a chess tree is also crucial for tournament and match preparation for professional players; a player is able to view an opponent's opening repertoire in just moments and can prepare accordingly. Even amateur chessplayers can use the tree for preparation. Many online correspondence chess sites offer downloadable databases of games which have been played on the site; it's possible to create a tree of games based on such a database to view an opponent's existing known repertoire and possibly find “holes” in an opponent's opening knowledge. 318 chessking.com
