january 25 2011

The rhythm is infernal in this month of January with the 3rd course of the Master. 

Noticed absence of talented composers probably exhausted by the overheating of the neuron of last Sunday.

For the hors d'oeuvres, the first etude is a light position that looks easy, but beware!
1 - White to play and draw

8/3k4/8/8/p1PK4/8/n7/8
W. : Kd4 Pç4
B. : Kd7 Na2 Pa4
=                              (2+3)


The second one is a set of brilliant moves from both sides.

2 – White to play and win

8/8/2P4K/3r4/4k1B1/2p4R/5n2/8
W. : Kh6 Rh3 Bg4 Pç6
B. : Ké4 Rd5 Nf2 Pç3
+                              (4+4)

Two helpmates for Daniel accompany a panorama of International Solving Contest that took place the day before yesterday. The solution of the two studies is given, the others will be given on request, if necessary.

An easy little quintet to get your brains going. It is amusing that the author, a specialist in disguises as he proved in Rio, has nevertheless not understood the flavour of his study, and has given an incomplete solution. But the circle of Saint-Lazare watches over...

At Gorgiev's, the melee will calm down to lead to an indispensable finesse to neutralize the strong black pawn.

An astonishing duel Knight versus Bishop where, against all odds, the Knight... manages, all by himself, to lose a tempo. We accompany it with a similar duel, in the form of a problem, where this time the King's tempi bring a precious help.

A kind of record: three "games of the day" this time, including two miniatures involving the same White player, but with a different outcome. With in all three cases an intense "virtual game". In Karpov-Hübner, an important variation forgotten by the speaker is 24...Nxh5! (instead of ...Nd7?) 25 Nf5 Bf4? (...Qf4!) 26 Qd5! (Karpov's analysis stops here) Ng7 27 Rf6! Nxf5 28 Qxf7+? (Rxf7!!) Kh8 29 Rxf5 Rxe7! (instead of Bd2). On the other hand, the 23 Qf6? in 21...exd5? (Beliavsky-Tal variation) proposed by the listeners, is refuted by a rook coming to e8 and threatening check on e1.

See you next Tuesday, February 1, if God wills.
Have a good time.

Nice sequence with some tips

To close, an exceptional work.
By a neat trick worthy of the greatest swindlers, the whites give the move back to Black at one point (with a Knight, that's unusual!)

3 – White to play and win

2k5/1pP1p2p/1K2p2P/3bP3/8/8/2N5/8
W. : Kb6 Nç2 Pç7h6é5
B. : Kç8 Bd5 Pb7é7h7é6
+                              (5+6)

The eagerly awaited dining part after the 3 games allowed the Master to take out of his bag some compositions in the absence of the composers mentioned at the beginning of the report.

First of all, a very airy position.

5 - h#4 Köko sentinels with Locust

8/8/2k5/8/4L3/8/8/8
Blancs : Loé4
Noirs : Kç6
h‡4                           (1+1)
b)Kc6,Lod5
c)Kc6,Loc4
Köko  : at the end of a move, a piece must have at least one piece on a neighbouring square
Sentinels : at each move, a piece (not a pawn), defecates a pawn of its colour on the starting square of the move
Lo=Locust: a piece that moves like a Queen and needs an opponent's sautoir to move. It arrives behind the sautoir which itself disappears

A small diversions by the Equihoppers.

6 -  h#3,5 Köko with Equihopper 2 solutions

4k3/5P2/8/1P6/2E5/1p6/1pp5/K7
W. : Ka1 Pf7b5 Eqç4
B. : Ké8 Pb3b2ç2
h‡3,5                        (4+4)
Circe : the captured piece is reborn on its initial square
Eq=Equihopper: a piece that bounces using a sautoir as the centre of symmetry

A bit tortured  

7 - serial s#13 Super-Circe

8/8/6K1/4p3/2p3b1/1r6/p1p1np2/qk6
W. : Kg6
B. : Kb1 Qa1 Rb3 Bg4 Né2 Pé5ç4a2ç2f2
ss‡13                      (1+10)
Super-Circe : a captured piece is placed on the board at the taker's choice
serial selfmate : white plays n moves in a row and black is forced to checkmate in 1 move

Sorry for the "Karpovian" lightness in the comments of the 3 games, but a multi-function clerk has little time.
 
Good reading to all
Yours sincerely

This delay is due to an internet failure that occurred on Thursday 27 January. The saboteurs of the Cours de Saint-Lazare vary their fields of action. After paralysing transport, they caught another type of communication.

Karpov-Hübner. Black did not give up on the 27th move, there were a few unimportant spasms. Whereas after 24...Nxh5! they could whistle.

Beliavsky-Tal: the virtual continuation obviously starts with 24 Nh5+!

Beliavsky-Larsen: in the variation 15...hxg6, you have to interpose 18...Qxg6 19 hxg6 before ...Bb4.

16...Bf8 doesn't really deserve a ? since it's ruined anyway.

The sautoir is gone, but it serves him right.

The squire is an invention of Master Remy, who will explain the march later. Patience.

The master clerk is not doing too badly, since he had three times as much work to do. But as he is not a Functionaries, he did not ask for a raise. He didn't even go on strike...

See you next Tuesday.
