Gnuchess has two display modes. The first mode is simply a normal mode that you could use with a terminal. The second mode is a fancy display mode you can use with a SUN workstation. To use the former, simply type 'gnuchess'. To use the latter, simply type 'chesstool gnuchess' on a SUN workstation where 'chesstool' is installed. In the latter example, the argument should be the path specifying where to find the gnuchess binary.
The level option when using 'chesstool' allows setting the search level time limit (in seconds). The default is 30 seconds. In other display modes, the user is prompted for a time limit. The search limit can be changed with the "time" command.
The following documentation assumes you are in the first mode (e.g. normal mode using a regular terminal). If not, then you should read the chesstool documentation.
For help once in Gnuchess type "help". To type in your move, use the notation "e2e4" where the first letter-number pair indicates the origination square and the second letter-number pair indicates the destination square. The letter indicates the column with the left-most column being "a" and the right-most column being "h". The number indicates the row, the first row (White's first rank) being "1" and the last row (Black's first rank) being "8". To castle, type the origin square of the king and the destination square of the king, just as you would do for a regular move.
