Champagne Tourney Jesi 2011

The Tourney is opened only to Congress Participants

This year, the tourney is dedicated to the memory of Alexandr Kislyak (27
XII 1938- 5 V 2010)

The Tourney is declined in 2 sections (with separate awards) :
A . ProofGames B. Any other kind of Retro problems

Theme :
2 Pawns originated from the same column promote.

Example A :
Mario Velucchi, L'Italia Schacchisticha 1997
SPG 6,5 2 solutions (15+14) C+

1.f4 g5 2.fxg5 f5 3.g6 f4 4.gxh7 f3 5.hxg8=B (Champagne!) fxg2 6.Bh7 gxf1=N
(Champagne!) 7.Bg6#
Thematical Pawns : f2 and f7.
The shortest rendering of the theme to be found in Winchloe.
But the problem doesn't fit for the tourney because of the not thematical
second solution(!) :
1.f4 Nh6 2.f5 Nxf5 3.g3 Nxg3 4.Bh3 f5 5.Bx5 Nf1 6.Bxh7 g6 7.Bxg6#

Splitting the theme in 2 phases (1 promotion in each) is accepted.

Example B :
Alexandr Kislyak, 1st Prize, Memorial Karl Fabel, Die Schwalbe 1976
1# (who?) (12+14)

Key to unlocking of the position is move b2-b3. White Bc1 has to go back
home before that. wN and bN have to unpromote in order to make the key-piece
wBc1 reappear (the Kislyak theme!).
-1…Ne5-c4 -2.Nd3-b2 Nc4-e5 -3.Nf4-d3 Ne5-c4 -4.Ng6-f4 Nc4-e5 -5.Nf8-g6
Ne5-c4 -6.f7-f8=N (Champagne!) Nf3-e5 -7.f6-f7 Ne1-f3 -8.f5-f6 e2-e1=N
(Champagne!) -9.f4-f5 e3-e2 -10.f3-f4 f4xBe3 (Kislyak!) -11.Bd4-e3 f5-f4
-12.Bb2-d4 f6-f5 -13.Bc1-b2 f7-f6 -14.b2-b3 Nb3-a1 -15.h2-h3! (not -15.e3-e4? :
wRh1 will not go back home; not -15.f2-f3? or -15.g2-g3? : bBa7 comes from
promotion by bPh after h3xg2-g1=B)
(also note that wBd8 comes from promotion by wPa after axNb and b7-b8=B)
As Knights cannot lose tempo, the unlocking doesn't work with last move by
White is to play and mates by 1.Nxc4#!. 1.Nxb2#? with black to play is
Thematic Pawns : f2 and f7.
The Kislyak theme is not requested but will be specially appreciated.

Fairy conditions allowed in both sections.
Maximum 3 entries per composer per section.
Maximum 1 non computer tested entry per composer in section A
