Then the right presentation is:

1-10 Shredder 7         2801-2737
1-10 Deep Fritz 7       2789-2732
1-11 Fritz 7            2770-2711
1-2? Shredder 7 UCI     2761-2638
1-15 Chess Tiger 15     2753-2700
1-15 Shredder 6 Pad UCI 2750-2703
1-16 Shredder 6         2750-2689
1-19 Chess Tiger 14     2744-2684
1-19 Deep Fritz         2741-2680
1-19 Gambit Tiger 2     2739-2681
3-2? Junior 7           2715-2659
