The chess engine that eventually evolved into Treebeard sprouted back 1976 within the chess program Merlin. In the nearly two decades that followed, its code morphed and had a notable appearance from 1997-2003 as the force behind Shotest, a world-renown Shogi program. Shogi originated 1,000 years ago after the early, Indian version of chess moved east from the Asian land mass to the Japanese islands.
In 2004 the Shotest engine was reworked for chess and renamed as Treebeard. The first appearance of its current form came with the release of the Global Star Tournament Chess II program, and it drives Microsoft's MSN Chess.
The game analysis Treebeard uses is unique and proprietary to AI Factory: unlike conventional programs, the engine does not search millions of positions to counter your moves. Instead, Treebeard uses a probability-directed search to examine fewer positions but with greater detail.
Rich features
With such a powerful engine driving AI's Chess Free app, your mental mettle will be tested, and, when combined with the app's well-designed user interface, you have the opportunity to hone your chess game to a sublime point.
Featuring 10 levels of difficulty, Chess Free is suitable for novice and expert players alike. Treebeard employs intelligent-weakening for the lower levels, which makes it perfect for beginning players, too. There's also a complete chess-move manual included for those completely unfamiliar with the game.
While there are many unique aspects of the app, one in particular proves helpful in improving your game at any level: the Show CPU Thinking option. Once activated, Chess Free reveals which move Treebeard is considering next by placing a blue border around the piece the computer wants to move and another around it's targeted square.
Customizable Play
If you want to try your moves against a person rather than a machine, the app also has a two-player mode. Just like when you play against the computer, the manual mode allows you to use a game clock that limits play from 5 minutes to 60 minutes and moves from 5 to 60 seconds.
Chess Free's user interface presents players with three chessboard layouts and three choices of chessmen to customize the feel of your game. In a game's Match Settings screen, the handicap adjustment feature offers an interesting twist, whether you're playing against the computer or a trash-talking opponent. In both modes you can choose to handicap the white chessmen by removing a pawn, knight, rook or queen. If playing the black chessmen against the computer, this option is particularly handy when testing your skills against Treebeard's higher levels.
After checkmate, you're immediately presented with the option to step back through each of your moves to see how you won, or lost, the game. Chess free also stores your gaming history and generates statistics based on your level of play against Treebeard.
The app features full touchscreen and trackball capabilities. The free version of the game is supported by unobtrusive banner ads.
Whether you're playing against Treebeard or against a living opponent, Chess Free will help you continually push the limits of your game.
