february 15 2011

 A few absentees, off to the slopes to try out the powder and no doubt the Mondeuse as well, did not prevent the core group from having a great time for this second and last session of February. 

The next one will be held in 4 weeks, that is to say on March 15th
For the appetizer (after all, we were under the protection of Saint-Claude), a superb composition by a very great 
1 – White to play and win
W. : Ka1 Rg5a3
B. : Kf8 Pé3f3d2
+                              (3+4)
One should not be afraid to play defensive moves without being fooled by optical illusions

Onkoud 2A regular on the course wins first prize in an English magazine. How is this possible with the Vladimirov 2the hereditary enemy? But because the judge was Russian, he doesn't care about the Hundred Years' War, or even Joan of Arc. And he is not just anyone: J. Vladimirov is himself one of the greatest multimove composers in history (the older ones will refer to the "Revue des Echecs" n° 3). He has just honoured our friend Abdel for a very beautiful 9# problem-study: the detractors of the problem (there are some) have no excuse, because mate in 9 is also the only way to win.

A long help, which does not mean boring. The right idea may even escape you for a while. And a 5# helpmate showing strategy... in 5 pieces! Two other fun multi-moves, the first one quite easy. Finally a selfmate 4-moves, a 2nd prize that seems to me better than the first prize.

A firework by the great Gurgenidzé. An astonishing complete circuit of Bishop, from another great composer, but younger.


In a desperate situation, think of stalemate. What do you mean, stalemate? With four white figures and two free pawns? This very recent Polish study is a bit reminiscent of Kazantsev's, which was demolished and never repaired in 50 years... until Pervakov took care of the matter in 2003. There is also a pinned piece and two immobilised pieces.



Today's game shows the weaknesses of a great player, which insiders had discovered more than 15 years before they became public knowledge, during a famous match.

It's time for a well-deserved break (especially for my listeners...): the next session, still God willing, is scheduled in one month, on March 15.
Have a good time.


The second one presents a very nice circuit
White to play and win
W. : Ké6 Bf4a2 Ph6h5ç4ç2g2
B. : Kh4 Ra6 Bd4 Pa7ç6a4
+                              (8+6)

Black's threat to play c5 pushes White to play the right move

The third is Polish with a position that seems hopeless for White.

3 – White to play and draw
W. : Kg3 Rf3 Bç8 Né2h2 Pd7g7a2g2
B. : Kd6 Rb5h5 Bç7 Nf4d1 Pg5a3d2
=                              (9+9)

One rook less but some dangerous pawns.
The threat is clear: Nxe2+ followed by Rh4#
The Master gratifies us again with a beautiful fight for the game of the day

A beautiful joust between two great swordsmen
The dining part starts very strong with an Isardam Super Andernach
 5 - h#4 Isardam Super Andernach 2 solutions
W. : Kb2
B. : Kg7 Rç7ç3
h‡4                           (1+3)
Isardam ; opposing pieces of the same kind cannot be observed
SuperAndernach : at each move a piece changes colour (this does not concern Kings)
Not easy to solve
A very elegant position to rest for a while
6 – h#4 Parrain Circe 2 solutions
W. : Kd2 Nf7 Pd3
B. : Ké6 Bf6 Nd4
h‡4                           (3+3)
Parrain Circe : a captured piece is reborn by making an equipollent move in the next half move from its capturing square
 There is a chameleon echo in this problem, it is quite aesthetic.

We see some Locusts in the next one
7 – hs#3 
W. : Kç6 Qb2 Rd5h3 Bh7 Pb5
B. : Qh6 Rb8 Bé5g2 Pb6d6f4a3 Loé4f3
hs‡3                        (6+10)
Lo=Locust : Grasshopper that swallows the sautoir, which is therefore necessarily an opposing piece
hs helped selfmate : white plays first and black helps him to present a selfmate 1 move on a board
A great economy for the next one
8 – serial h=24 Exchange Circe with Berolina Pawn
W. : Kç7 BPf1
B. : Ka8
sh=24                        (2+1)
Exchange Circe : after the capture, the captured piece is reborn on the starting square of the capturing piece's move
serial helped stalemate : black plays n moves in a row to help white present them with a stalemate in 1 move
Berolina Pawn : pawn that advances diagonally and captures by advancing on the column
9 – h#3 Anti-Andernach Chameleon with twin
W. : Pd7
B. : Kh8 Pe2
h‡3                           (1+2)
Anti-Andernach : a movement of piece without capture makes it change colour
Chameleon : transformation cycle Q – N – B – R – Q
With the twin, we have an AUW
And the last one in Mirror Circe
10 – h=3 Mirror Circe
W : Kg4 Bé6b2 Pb7g7
B. : Kd6 Nç8 Pb3a2é2
h=3                           (5+5)
Mirror Circe : a captured piece is reborn in the opponent's house according to the same modalities as the "normal" Circe
 This report ends, it remains for me to wish you good reading.

Mestre's corrections

The 9th white move is 9 exd4, which is 9 ed for short. But you can rectify this yourself.

In 13...Nd5 it is 16...Nxd1. Same remark.

The master-tabellion has omitted the good defence 30...Re8! (to be followed by ...Re6!) which makes my remark about the "weaknesses of a great player" more understandable.

Enjoy for a month.
