Shane's Chess Information Database (Scid) is a free and open source UNIX, Windows, Linux, and Mac application for viewing and maintaining large databases of chess games. It has features comparable to popular commercial chess software. Scid is written in Tcl/Tk and C++.
With this program one can create huge databases, run chess engines, and play casual games against the computer or online with the Free Internet Chess Server. It was originally written by Shane Hudson, and has received strong contribution from Pascal Georges and others.
Notable is the ability of this interface to modify Polyglot (.bin) books.
