[Retros] Champagne in Portoroz : solutions

[CAILLAUDM at aol.com]

Here they are, along with my original comments :

1st Prize
Reto Aschwanden (Switzerland)
2 promoted pieces, a Bishop and a Rook, perform a "square" circuit. En 
passant, the Donati-50 theme, with only the necessary white moves.

9.g5 Sç5 10.Bd7+ Kb7 11.g6 Ka6 12.g×f7 g6 13.f×g8=R Bh6 14.Rg7 Rdg8 15.Rf7 
Rg7 16.Rf8 Bf7 17.Rg8 e6 18.Bç8+

2nd Prize
Paz Einat, Gady Costeff, Ofer Comay (Israel)
An orthogonal and a diagonal Excelsior. A picturesque idea!

Special HM
Ivan Denkovski, Gligor Denkovski (Makedonia)
The thematic elements are the Zepler-Turton manoeuvres with wKa1 and wRb1 on 
orthogonal line and wPe6 and bBf5 on diagonal line. But other elements of the 
rich solution (Ceriani-Frolkin,...) make the theme appear not so clear as in 
the prized problems.

1st HM
Joost de Heer (Netherlands)
Tempo oscillations performed by wRh1 then by wBf1 with help of a well-known 
introductive play. 
1.Sf3 a5 2.Sd4 a4 3.Sb3 a×b3 4.a3 Ra4 5.Ra2 b×a2 6.Rg1 a×b1=S 7.Rh1 Sç3 8.Rg1

Bg2 16.h3 Bh1 17.Rg6 h×g6 18.Bg2 Rh5 19.Bf1 Re5 20.Bg2 f5 21.Bf1 Sf6 22.Bg2

2nd HM
Igor Vereschagin (Russia)
Clearcut realization with a diagonal and an orthogonal double check.
1.a4 g6 2.Ra3 Bg7 3.Re3 Bç3 4.d×ç3 Kf8 5.Q×d7 Kg7 6.Qe8 Bd7 7.Kd2 Kh6 8.Kd3 
Bb5++ 9.Ke4 Qd1 10.Rh3++

1st Com
Marek Kolcak (Slovakia)
Almost all the moves are thematical in this elementary but ingenious problem! 
A piece (Rook or Bishop) goes to free a piece that will take its place.
1.h4 e6 2.Rh3 Bb4 3.Rb3 Bç3 4.Rb6 a×b6 5.b×ç3 Ra4 6.Ba3 R×h4 7.Bf8 Rh1

2nd Com
Bjorn Enemark (Danmark)
The echo runs between the 3 moves of the white and black Queens.
1.d4 e5 2.Bg5 e×d4 3.Q×d4 Q×g5 4.Q×g7 Q×g2 5.Q×h7 Q×f1+ 6.K×f1 R×h7
