Turing described his own algorithm as being able to play a low-level game of chess. Placing the king in check could be attributed a half a point for example. For example, if a knight is worth 3 points and a queen is worth 10, the algorithm will vote for the move that earns the most points in the short run. This evaluation algorithm is primarily centered around deciding whether to take a piece or not. Turing’s Turochamp works by taking in the adversarial player’s move as input and calculating all of the possible moves, as well as the player responses, and attributing points based on the moves. Of course, these values can vary depending on the position:
Bishops and knights have usually attributed 3 points, rooks are worth 5 points and the queen is worth 10 points conventionally. One centipawn is 1/100th of a pawn, which is usually worth one point in chess. The score is usually calculated in centipawns. Positive values mean a position is better for the white pieces, and negative values indicate the position is better for the black pieces. In the graph below, we can see a graph of the score attributed to a position. Using this, we can have an idea of who is winning at which point in the game.

Kings can also make the special move castling, where it moves two squares left or right toward a Rook and the Rook is moved in to the square the King just crossed. Kings: Kings can move one square in any direction as long as the square they are moving to is not under attack.Queens: Queens move horizontally, vertically, or diagonally any number of squares, though they do not jump other pieces.Rooks also move as part of the special Castling move. Rooks: Rooks can move horizontally or vertically any number of squares, though they do not jump other pieces.Bishops: Bishops can move diagonally in any direction any number of squares, though they do not jump other pieces.When Knights move they are able to jump over intermediate positions. Knights: Knights move in an 'L' shape, where they move two squares horizontally or vertically & one square in the other direction.Pawns also have a special move named En Passant, which allows them to capture an opposing pawn which is paralle to them while jumping forward at an angle to another cell. When pawns capture opposing pieces they move forward at a diagonal rather than directly forward. Pawns: Pawns move one space directly forward, though you can move them 2 pieces forward as their first move.If you play against the computer your score is based on how quickly you play. The game shows a counter clock in the bottom right for the first player & a play clock in the upper left for the computer or second player. The game ends via stalemate (when one player can not make a valid move) or checkmate (when one player has the other player in check and can not move the king out of check). Players move any of their 16 pieces per standard chess rules.
The playing grid consists of a 8x8 grid of 64 cells. The first player controls the white pieces & the computer or second player control the black pieces. When playing against the computer you can set the difficulty at 1, 2, or 3 stars. Select single player to play against the computer, or select two players to play against another human computer sharing your computer. Try the game in it's own window by clicking here.
