I'd just like to congratulate all who have participated in the 'EGTs Online' initiative and reached the '3x+' milestone for all EGTs.
This success has required a combination of vision, commitment, technical skill, generosity, patience - and cash. Well done. g
Congratulations to all ...

7-man bitbases
Certainly, Marc B could create 7-man bitbases from his 7-man DTZ EGTs.
There are choices here: one could create wtm/btm 2-bit-per position arrays for (win, draw, loss, other).
Or one could create wtm/btm 1-bit-per-position win/not-win and lose/not-lose arrays. The latter would appear to require less space _and_ time in use.
I also believe, on the basis of a theoretical argument, that it is quicker to generate a DTx EGT via bitbase-generation than directly.
SHREDDER 10 shows (I think) the number of accesses to its SHREDDERBASES and Nalimov EGTs: if so, it certainly shows the utility of the former.
