Great job yet again Sarah,

The margin of 1st & 2nd over 3rd (38+-, 53+-) is quite big.

For my own interest I made the following crosstable of your top 6 ranked
programs, as if they had only played those 5 opponents.

Fritz 7a 		17.5	25.5	15.5	22.5	23.5	104.5
Fritz 7b   	22.5		17	21.5	21.5	27	109.5
ChessTiger14.0	14.5	23		25	21	22.5	106
GambitTiger2.0	24.5	18.5	15		20	23	101
Fritz 7	        17.5	18.5	19	20		19	94
Fritz 7(No MMX)	16.5	13	17.5	17	21		85

The only conclusion I draw is that Fritz7a reached its top spot by performing
better than 7b, & CT14, against the "lower" opposition.

Very interesting tournament Sarah,
Thanks again.
