My free chess software (for Windows)

Chessboard Capture Program

This tool allows you to capture an image of a chess diagram from your monitor and convert it to FEN (a form acceptable to database and other chess programs).  To obtain it download (below). Documentation of the tool can be found here.  A YouTube video (a bit out of date) describing how to use it is here.  A new version, 6.2, is an improvement to the learning algorithm.

Guess the Move Program

The Guess the Move Program lets you play over chess games, guessing the move for the winning side before you see it.  It scores your move and the whole game by using a chess engine to evaluate the positions you obtain. GTM has had over 20,000 downloads on To get the program download (below). The User's Guide for GTM can be found here. A YouTube video (somewhat out of date) describing the program can be found here.

Yatt -- Yet Another Tactics Trainer

Yatt presents chess puzzles to you using a spaced repetition algorithm.  It contains about 5500 puzzles. To get the program, download (below). The user's guide for Yatt can be found here. There is a video (for a previous version) here.

Chess Speak -- A Voice Interface to a Chess Engine

ChessSpeak allows you to speak moves to any UCI chess engine and receive the engine's move in audio.  This lets you set up a real board and pieces across the room from the computer and play a game against the engine without having to use the mouse, keyboard, or monitor.  Some find this a more natural way to play chess and their "board vision" benefits from using actual pieces. You can use the program to practice blindfold chess; I also tried to make it useful for blind players. ChessSpeak has a graphical interface as well. Additionally, ChessSpeak will calculate your rating and ratings for chess engines. To get the program download (below).  The user's guide for ChessSpeak is here.  There is a YouTube video (not of the latest version) here.
