Subject: GAMES:  MChessPro vs. ChessMachine
Date: 2 Jan 93 12:31:00 GMT
Organization: Not Very Ltd.

I've been asked to post some games of the match, but first some
overall impressions about the two programs.

My friend says, that the endgame knowledge of MChessPro is definitely
a big plus.  Another factor is the bigger opening library that leads
to an increase of search time for MChess.  MChess loves double bishops
and also knows how to play with them.  And MChess's play seem to be a
bit more aggressive and directed to the enemy king.

All these factors, though small by itself, sum up to a better performance.
It's not that you can put your finger on one thing and say "this is it".
