Dear problem friends,
the Valladao task does not need a UNDER-promotion. The 1.and 2. prizes in
the Valladao Tourney had a promotion of Q (or R).
Best regards

Dear Alain (and dear Gianni),

this is a very nice introduction to proof games! It should perhaps be made
available on the home page of the Retrograde Analysis Corner.

I have a few corrections and comments:

a) Below diagram 4, the stipulation should perhaps be given very exactly as
"PG in exactly 4.0 moves" (because it is not a shortest proof game).

b) Above diagram 5, print "Schweizerische" instead of "Schwizerische".

c) Between diagram 7 and diagram 8: "occurs" instead of "occur"?

d) Between diagram 8 and diagram 9, the text may be misleading, because the
Ceriani-Frolkin-theme is not necessarily connected with the Phoenix theme.

e) Between diagram 10 and diagram 11, the Valladao task is mentioned. There
is some controversy whether this task requires an UNDER-promotion.

Best wishes,
