from 66.Qc8+ Ka7, this seems to satisfy me that the human assertion I made to
Frederic on the Playchess server that this position is drawn was not false.
However, while I'd seen 66.Qa4+ going nowhere (and hadn't tried 66. Qc8+ yet),
I did underestimate the danger of the quiet 68.Nd5! in the 66.Nc7+ main line,
thinking Black had oodles of checks and then time to cover. KWR 4/ 4/06 10:
40pm ET---after I see if 66.Qc8+ Kb5 holds too this closes the book. 3:

. . . . . . . . . . . . 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.

right away! This sets up again a capturing White piece being on the edge of
the board so unable to defend checks and contributing to possible stalemate.
Unfortunately I have to choose between viewing 2-or-more lines, seeing at

coming down, or...how would you explain 5.89 coming down?? . . . . . . . . . .
. . . . . . . . OK, still doing 75.Kd6 at 15/65 the first slip, down to +6.81,
00:10:53 elapsed, 1301267kN, and ! tb=134654! . . . . . . . . . . . . . . . . .

. . . . . . . . . . . . . In human terms, I can see why after 75.Kd6 Black has
to retreat the Rook. 75... Qa6+ 76 Ke5 is a cozy hiding place, and 75...Qg2 76
Kc6 leaves the Rook hanging with BQ not covering d3 anymore. . . . . . . . . .

has been patiently waiting for 60 minutes past her usual walk time! My wife is
guiding my kids' music practices and grading papers...But the analysis will
still be in the window, so off I go. I just wanted to be here in person to see
the expression on Fritz's face when that majestic +7.09 comes a-tumbling down!

after hitting OK for this text box highlighted one of the analysis lines and
made it re-start---I didn't think that would happen on a clipped *text* line,
as opposed to a move! Now it says at 16/16: . . . . . . . . . . . . . . . . . .

. . . . . . . . . . . . . . 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... . . . . . . . . . . . . . . . . . . . . . . . . . . .
