Gerard, hope that Damy can agree with the whole move sequence, so that it is confirmed that white wins.
My holiday ends, so I will have less time in the next months for BT Draughts.
I will at least do a verification step for all DBs, and evaluate if the generate proces can be improved (so faster), as with the current speed it still takes too long to strongly solve 8x8 BT draughts (although from a scalability point of view it would be possible if I have a 5 TByte HD, as the current implementation does not compress).
For really fast analysis of all moves in any position, I guess I most likely need to generate the 15P and 16P DBs (as Rein predicited).
The 7x6db is now completed but, as expected, it does not really improve the picture in order to solve the starting position. We all now that the far most time consuming variants are those with balance material between white and black. I made great progress with the 6x6 db but not with the 7x6 db. The decisive db will certainly be the 7x7 db.
If you want to go farther than the 14P db your goal should be to generate the 8x7 db and then immediatly the 8x8db, ignoring 9x6, 10x5 etc db.
Anyway my intention is to complete the 13p pieces db; 8x5 is under generation.
BTW I continue in a monothread configuration because I suspect I will be able to generate the 7x7db BEFORE coding and debugging a multithread generation!
