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
rnbqkb1r/ppppp3/6B1/8/8/8/PPPPP2P/RNBQKnNR
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
rRbB4/bBqpp1p1/1krp4/2p5/K1n1P3/RP4PP/pNPP4/n7
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.
White  is to play and mates by 1.Nxc4#!. 1.Nxb2#? with black to play is  
illegal!
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
