I don't know if this exists, but it would be cool - You want to review a game, but you're at work. So, you download your pgn file, go into a command line environment and type:

cchess mygame.pgn -p2w

and the programme loads up mygame.pgn, and displays the position at move 2, white's go - in nothing but ascii type characters.

Then, allow for branching, comments etc, by typing

cchess mygame.pgn -b2w qe2

or

cchess mygame.pgn -c2w "Cunard Defense"

Anyone with any experience of a command-line only programme with features such as these?

Windows is great, but wouldn't it be good to have chess at your fingertips without all that messing about with mice getting in the way!
