What is Chinook Checkers?

Chinook checkers 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 history and achievements of 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.

In 1995, Chinook defended its man-machine title against Don Lafferty in a 32-game match. The final score was 10 with 31 draws for Chinook over Lafferty. After the match, Jonathan Schaeffer decided not to let Chinook compete any more, but instead try to solve checkers. At the time it was rated at 2814 Elo. The solution was achieved, and the result published in 2007.

The features and benefits of Chinook

Chinook's program algorithm includes 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 with artificial intelligence.

Playing against Chinook has several benefits, such as:

  • Boosting your memory recall by remembering previous moves and patterns

  • Developing your concentration skills by focusing on the game and avoiding distractions

  • Enhancing your problem-solving abilities by finding the best moves and strategies

  • Learning from your mistakes by analyzing your losses and improving your skills

  • Having fun and challenging yourself by playing against a world-class opponent

  • The board consists of 64 squares of alternating colors, arranged in an 8x8 grid. Each player has 12 pieces of one color (black or white).

  • The pieces are placed on the dark squares of the first three rows on each side of the board. The black pieces move first.

  • The pieces can only move diagonally forward, one square at a time, to an empty square.

  • If a piece reaches the opposite side of the board (the king row), it becomes a king and can move diagonally forward or backward, one square at a time, to an empty square.

  • If a piece can jump over an opponent's piece that is adjacent to it and land on an empty square behind it, it must do so. The jumped piece is removed from the board. If a piece can make multiple jumps in a row, it must do so. A king can jump over pieces in any direction.

  • A player wins the game when he captures all of his opponent's pieces or blocks them from making any legal moves. A game is a draw when neither player can win or when both players agree to end the game.
