Suppose 7 men or more were desired? How much RAM needed to do the job? Maybe most people do not have that much RAM. That might drastically cut down on the number of people who could generate multi-men tablebases. Perhaps a very large computer, or maybe a special purpose computer would be needed. It might also be possible to create a new algorithm for generation of tablebases which would accommodate smaller RAMs at the expense of maybe taking longer [and much swapping with hard drive?]to generate the tablebases. There is another issue: Suppose that 7-, 8-, or 9-man tablebases were available. Would an ordinary PC be able to utilize such tablebases? Would existing chess-playing programs [GUIs?] be able to work with such large tablebases? It takes a little bit of time to load Fritz as it is. Maybe use of very large tablebases would make it take forever to load. Perhaps there are other practical limitations to the use of very large tablebases too. Thoughts = ?
