Does anyone have subscription price/information for Themes-64 or
for other chess problem/endgame periodicals?  Thanks.


From an old article of mine:

According to Tim Krabbe (Chess Life & Review, Oct. 1975 and _The Best
of Chess Life & Review_ Vol. 2):

Wagner-Duehrssen, Corr. Game, Germany (1927).

7. resigns


Sokolsky-Ravinsky, USSR (1938).

Reschko-Kaminsky, Leningrad (1972).

1. a8=B Qb3
2. Qd7  Qg8
3. Bd5 and Black lost on time

This game also appears, with some analysis, in Nunn's _Tactical Chess
Endings_ pp. 66-7, where he states that this is the only game known
to him where a required bishop underpromotion occured (he apparently
wasn't aware of the other two).


From an old article by John Pope:

Also, I just saw a study on a demo board in a local games bookstore
where promotion to a B is necessary (it's by Haines, presumably a
local):

         8 - - - - - - - -
         7 - - - - - - - -
         6 - - - - - - P -
         5 - - - - - - - -
         4 - - - - - p - p
         3 - - - - - P k p
         2 - - - - - - - -
         1 - - - - - - K -
           a b c d e f g h

The solution wasn't posted, but I believe it is:

1.g7 h2 2.Kh1 Kh3 3.g8(B) Kg3 4.Bd5 Kh3 5.Be6 Kg3 6.Bg4 h3 7.Bh5
Kh4 8.Be8 Kg3 9.Bc6 +-
