Marc Bourzutschky just sent me complete stats for 440 endgames, that is - all
3-6-man endgames apart from 5-1.
On my 1GHz laptop, 3-5 man was 3 hours and P-less 3-3/4-2 took a few overnight
runs only. MB reports that the full DTC run was much quicker than the DTM run
(so you may infer that he's done that too!). I have proceeded more slowly
through the 6-man P-endgames because I'm down to 9GB disc: the uncompressed
EGT_files can be 0.8GB, .nbb+.nbw.
I ran the .tbs files past a program Rafael Andrist sent me, which was able to
look at most of them: it doesn't pronounce on 3-3p endgames yet.
I may be using this program 'out of scope' as it is expecting a .tbs for a
Nalimov compatible 8x8 game but I don't see problems so far.
So far, KRNNKQ has the maxDTC = 169 for 1-0 wins (-v- 28 for 1-0 wins and 41 for
0-1 wins on 8x8). Other games have deeper maxDTC on 6x6 than on 8x8.
KBBNKR maxDTC is notably 112 (v 68 for 8x8).
I'm beginning to think that Ns are less wieldy on 6x6. I initially thought
they'd be more useful as they cover a larger % of the squares but this looks
wrong now.
In 4-man, KRKB is deepest, going up from 18 (8x8) to 42. In 5-man, KBBKQ 0-1 is
deepest at DTC = 70 (v 71 for 8x8). 4-2p: KRNPKQ is deepest at 100 (v DT_M_ of
123 for 8x8: no DTC available).
I have not generated KRNPKQ myself but here are maxDTC lines re KRKB, KBBKQ,
KBBNKR and KRNNKQ:
