Tarrasch GUI

Tarrasch is intended to be simpler than any other chess GUI to use. Tarrasch doesn't restrict your freedom. Move the pieces around the board, setup any position, start playing against the engine of your choice with either color from any position at any time. Change the clock settings at any time, go ahead, give yourself a nice time handicap against the engine! You can even set the clocks to be visible and running when you're not playing the engine, that way the GUI serves as a simple board, men and clocks for a game against a real human opponent.

The simplicity and freedom of Tarrasch doesn't mean there are no powerful features. Tarrasch can use any .pgn file as an opening book. Tarrasch has an 'open book' philosophy, so you can see the book moves available at any time and you can tell when the engine has played a book move. Tarrasch will even prompt you with the book moves available if you choose a non book move. This feature, inspired by Reptor (an earlier Triple Happy program - see 'What happened to Reptor ?' below) helps you memorize opening moves.

The .pgn book that comes with Tarrasch includes training positions. It is very easy to setup any of these training positions and work on your technique by practicing against an engine from the training position. Tarrasch will remind you of the book move if you stray from a path stored in the .pgn book.

Tarraschwill make it very easy to create your own .pgn files, so coaches can use Tarrasch to create their own training exercises for pupils.

Tarrasch has full or partial blindfold modes, and a 'play N half moves behind' mode. These innovative training features designed to help you improve your ability to see ahead. The Tarrasch Toy Engine is an ideal opponent using these modes (you don't really want to handicap yourself when you're playing Rybka!).
