81 between 22 and 23 ply---it was so already around 20 ply. It sez 22/74, so
some lines went 37 deep. (Without EGTs mind you.) This MUST mean *stasis*.
There are only 32 squares for WB, 60 for WN, 60 for BR, 15 for BK except in
lines where something has happened, ditto IMHO for WK, x 2 for player to move.
That's 30x2x60x60x15x15 = "only" about 45 million nodes. My 2 billion bytes of
RAM can handle that! I'm getting 1946kN/s here, i.e. 2 million nodes per
second. Even with much redundancy of node visitation, 45 million can fill up
very quick. And really the vast majority of "45 million" are likely nodes
where Black will queen or White's e-pawn drops. So really less than 1 million
rational combinations---less than 100,000 I really bet---easily saturated! So
I deduce that there are no more long Zug maneuvers---I should really test
Fritz on a long EGT win like the 122-mover in my "EMstudy.html" file in /.../
regan/chess/studies/---so this must be tantamount to proved a DRAW! Ah---at 22
ply, now 65 Bc3 shows only "+1.63" (as the 6th line---I had 6 showing). Is
this a sign of stasis beginning to be recognized? No time to find out right

. . . . . . . This is quite a confidence-shaker, for reasons different from my
finding what I humanly concluded is a positional draw which was evaluated at
+2.60 for many, many moves at many, many ply. This goes to the heart of the
nature of "proof". An eval of +5.89 that persists for a long time ought to
mean you really have something! However, I see a possible chessexplanation---on
e I might see if I go down to 1 line? As I see it, either: (1) There is a line
where Black loses his Rook but can give a perpetual check. This is a surprise
on an open board when White has two minors plus the Queen. I don't think it
could be a simple perp. in a corner, since I'd expect singular extensions to
catch it quick, but maybe there's a medium-sized one where WK is kept pinned
against WQ. Ah! it *could* be a *big* one where squares are available to BQ
because of a stalemate defense! (2) There is a hashing bug. It is commonplace
in my field of complexity theory to employ hash families for which the chance
of collision is believed to be infinitesimal but for which this hasn't been
*proved*---it's something like the "P = NP?" problem. Note that Shredder
suffered a high-profile hash error, hanging a Bishop at the WCCC last year,
with the explanation being that it thought it was playing a different position.
.. (3) Fritz gives a high eval for White's attack and central control and +2
in raw material, then lowers it when it stops seeing chains of threats. This
seems to be the explanation of how Fritz identifies promising lines to pursue
*coming in to* a position like that before both pawns Queened. But enough of a
plus to give +3.89 of extra eval? I don't think so...that I consider this
possibility to be eliminated is why I was querying on Saturday morning to
begin with... So it's perpetual or bug! My money is on the perp, but I shall
find something definite either way. At 17/17 I get more info: . . . . . . . . .

newly-reflected evaluation, i.e. the previous think did enough of
there-evaluat ion to propagate the hash values. So now of course I'll let it
go a long time while walking my dog (named Zoey, not Fritzi:-) to see how

. . . . . . . . . . . . . . NOW, one reason I am doing this only with 5-man
EGTs although I could fit *some* 6-man EGTs on my hard drive is that I regard
the 5-man EGT verdicts as humanly explainable, but the 6-man EGTs as not. I.e.
with 5-man EGTs I am reasonably confident I can identify the major ones being
used even though any chess engine will *hide* those evaluations that cause
lines to fail. Whereas with 6-man positions, all the time in this file you see
I am looking up the ones that matter *manually*, at the K4IT server! (The
*second* reason I am doing this is that by using no-more-than-5-man EGTs to DO
the analysis, and later 6-man EGTs to CHECK the analysis, I can gain much
greater confidence in the verdicts! Indeed I originally had no EGTs on at all..
.) However, when I see 540,772 EGT evaluations being done in 33 minutes and 58
seconds, maybe I should say I *was* reasonably confident of identifying the
major ones being used... . . . . . . . . . . . . . . . . . . . . . . . . . . .
