 Hi Chris! No, sorry I don't have any place to put the files - but for those
 interested in the games, I can send them by mail. I was surprised from the
 richness and variety of the games. And this from a very simple position,
 technically spoken. The greatest danger for black is to trade down to a
 pawn ending. Deep Fritz managed to win 4(!) games with the black pieces -
 but also lost as black vs Shredder in 17 moves! Heavily misplaying a
 pawn ending...In this game it was okey to trade rooks since black already
 got rid of his double pawn - giving 3-2 pawns QS and 2-3 KS from black's
 viewpoint. But the pawn ending was a disaster for DF...
