Hello,

If you have the Tablebases....Let's use Krb vs kr as an example....
Set up the position. Then click on to the infinite analysis button Which is the
Magnifying Glass ICON or press the Alt+F2 keys. Once you do this, you will see a
long list of mating or drawing moves or both in your engine window pane. This I
am showing below as an example. If you do not have the particular endgame in
your tablebase folder, you will only have evaluations showing in your engine
window pane.
Analysis by Fritz 7:

1. +- (#3): 1.La6
2. +- (#3): 1.Te6
3. +- (#3): 1.Tf6
4. +- (#3): 1.Tg6
5. +- (#3): 1.Th6
6. +- (#10): 1.Td6
7. = (0.00): 1.La4
8. = (0.00): 1.Lc4
9. = (0.00): 1.Ld3
10. = (0.00): 1.Le2
11. = (0.00): 1.Lf1
12. = (0.00): 1.Kc5
13. = (0.00): 1.Tc5
14. = (0.00): 1.Tc4
15. = (0.00): 1.Tc3
16. = (0.00): 1.Tc2
17. = (0.00): 1.Tc1
18. = (0.00): 1.Tc7
19. = (0.00): 1.Tc8+

 I don't have any answers involving the 6 man Tablebases.

Best Brian
