It is for the blind, low sighted or those who can not use a mouse. It provides vocal announcements of position changes and other selectable board conditions. Blind players also use a separate "tactile chess board". Winboard 4.5 has full keyboard access to move pieces and run menu items. Partial sighted players use high contrast mode and adjust board, piece, most font sizes and colors. Available languages are English, German, Spanish, Italian, Dutch and Russian. Games may be viewed, modified or saved in standard PGN format. Two Chess engines supply play and grand master strength move analysis. Connect to the Free Internet Chess Server (FICS) and play humans. Modify verbosity in screen reader configurations and in the Winboard "Sound" dialog under the "General" menu. Find all documentation in the "doc" folder under the Winboard directory of your C drive.

SAN Kit was made public in 1993 by Stephen Edwards, the inventor of PGN Chess notation. The original code is in C, and with few comments quite cryptic. In addition, the original author's style was quite quixotic, making it even more difficult to read. This code is now reformatted to modern standards, adds support for NAG codes and comments, and has a "non-CLI" mode for inclusion in chess playing programs. The code has gone through extensive analysis using the llvm/clang compiler and reports no issues at this time. To use the code as a "framework" you would undefined "CLI". In addition, a small C++ program is included that takes as input a file of one or more PGN records, and outputs pure pristine PGN records as output. In addition to flagging errors at the move level, the program provides three boards around the move. NOTE: plan on budgeting a fair amount of time to read, re-read, and experiment with the documentation and cryptic uncommented code. You are on your own

icsdrone acts as an interface between an ICS (Internet Chess Server) and a chess engine supporting the XBoard/WinBoard protocol. Unlike XBoard/WinBoard it does not use a graphical interface so it is suitable for use on embedded systems. icsdrone was originally developed for FICS (the Free Internet Chess Server) by Henrik Gram but currently ICC (the Internet Chess Club) works as well. Some features - "Daemon mode" (run in background). - Auto reconnection in case of network problems. - Builtin support for using timeseal. - An ICS proxy. When instructed via the "proxy" option, icsdrone acts as a proxy for the ICS it is connected to. This is similar to using xboard with zippy but now the "GUI" (xboard/winboard) can be closed without terminating the engine.
