Nalimov tables buggy? Rather the implementation :-)


http://www.shredderchess.com/online-chess/online-databases/endgame-database.html

I tried to check my old KPP/K problem (and the possibility to make an excelsior
out of it). So Kg7 Pe7 Ph2/Ke1, 1.h4! Too bad for me e8Q is also are 9# (I knew).
Too bad for the site maintainer that h4 only draws and e8B or S even lose for White
(well, that's new to me :-)
(Note added in proof: Aha! Somehow I managed to define a ghost pawn on d2 which doesn't
show on the diagram and can't be removed. Wonders of Javascript :-)

I tried your position Kg7 pe7 ph2 / Ke1 on this site and the results were:
1.h4/e8=Q/Kf7/Kg6/Kf6 win in 9
1.h3/Kh6/Kf8/Kg8/Kh7 win in 10
1.e8=R/Kh8 win in 11
1.e8=B wins in 13
and finally 1.e8=S wins in 14.
Maybe you should try it again?

"Again" is the magic word :-)
Of course I get the correct result when being *first time* on the site,
it's presumably something with the cache (the site maintainer said
they had *some* problem...unspecific glitch type bugs are a nuisance).
