Introduction
What is Chinook?
Chinook is a computer program that plays checkers (also known as draughts). It was developed between the years 1989 to 2007 at the University of Alberta, by a team led by Jonathan Schaeffer and consisting of Rob Lake, Paul Lu, Martin Bryant, and Norman Treloar. The program's algorithms include an opening book which is a library of opening moves from games played by checkers grandmasters; a deep search algorithm; a good move evaluation function; and an end-game database for all positions with eight pieces or fewer. All of Chinook's knowledge was programmed by its creators, rather than learned using an artificial intelligence system.
Why download Chinook?
Chinook is the first computer program to win the world champion title in a competition against humans. In 1990 it won the right to play in the human World Championship by being second to Marion Tinsley in the US Nationals. At first, the American Checkers Federation and English Draughts Association were against the participation of a computer in a human championship. When Tinsley resigned his title in protest, the ACF and EDA created the new title Man vs. Machine World Championship, and competition proceeded. Tinsley won with four wins to Chinook's two, with 33 draws. In a rematch, Chinook was declared the Man-Machine World Champion in checkers in 1994 in a match against Marion Tinsley after six drawn games, and Tinsley's withdrawal due to pancreatic cancer. While Chinook became the world champion, it never defeated the best checkers player of all time, Tinsley, who was significantly superior to even his closest peer.
By downloading Chinook, you can play against the world champion in checkers anytime you want. You can choose from different levels of difficulty, from novice to intermediate. You can also select your preferred color, either red or white. You can get feedback from Chinook on your moves, and learn from its opening book and endgame database.

Tips and tricks to improve your checkers skills
Learn the rules and notation of checkers
Before you play against Chinook, you should make sure that you know the rules and notation of checkers. Checkers is played on an 8x8 board with 12 red and 12 white pieces. The pieces move diagonally forward one square at a time, except when they capture an opponent's piece by jumping over it. A piece that reaches the last row of the board becomes a king, which can move and capture in any diagonal direction. The game ends when one player has no legal moves left, or when both players agree to a draw.
Checkers notation is a way of recording the moves of a game using numbers and symbols. Each square on the board has a number from 1 to 32, starting from the bottom left corner and going up and down alternately. A move is written as the number of the square where the piece starts and the number of the square where the piece ends, separated by a dash. For example, 9-14 means moving a piece from square 9 to square 14. A capture is written as the number of the square where the piece starts and the number of the square where the piece ends, separated by an x. For example, 14x23 means capturing a piece on square 23 by jumping over it from square 14. A sequence of captures is written as a series of numbers separated by x's. For example, 14x23x32 means capturing two pieces on squares 23 and 32 by jumping over them from square 14. A king is indicated by adding a K after the number of the square where it is. For example, 32K means that a piece became a king on square 32.
Study the opening book and the endgame database of Chinook
One of the reasons why Chinook is so strong is that it has a vast knowledge of checkers openings and endings. Chinook's opening book contains over 500,000 moves from games played by checkers grandmasters. Chinook's endgame database contains all possible positions with eight pieces or fewer, and their exact outcomes. By studying these resources, you can learn how to play the best moves in different situations and avoid common mistakes.
You can access Chinook's opening book and endgame database by clicking on the "Book" and "Endgame" buttons at the bottom of the screen. This will open a new window where you can see Chinook's recommendations for each position. You can also enter any position you want by clicking on the "Edit" button and moving the pieces on the board. You can then see what Chinook thinks about that position and what moves it would play.
Analyze your games and learn from your mistakes
Another way to improve your checkers skills is to analyze your games and learn from your mistakes. You can do this by using Chinook's analysis feature, which shows you how Chinook evaluates each position and move. You can also save your games and review them later by clicking on the "Save" button at the bottom of the screen. This will create a file with your game in checkers notation, which you can open with any text editor or checkers software.
By analyzing your games, you can see where you made mistakes or missed opportunities, and how you can avoid them in the future. You can also see what moves Chinook would have played in your place, and how they would have changed the outcome of the game. You can also compare your moves with those of checkers grandmasters, and see how they handle different situations.
