october 4 2011

The Master has spoiled us with a number of studies for this new school year, a number of which have emerged from the
world solving championship which took place during the summer.
The audience, thinned out by a summer of withdrawal, was also thinned out in number.
The next session is scheduled for next Tuesday 11 October

Queen's dominance as an introduction.

1 - White to play and win
Moravskoslezský deník 1927
2° Prix
W. : Kd4 Rg7 Ba3 Pd3a2
B. : Kh8 Pa4h2
+        (5+3)

Very nice composition

The second one has the charm of the long variations on the tightrope.

2 - White to play and win
W. : Kd1 Rh3 Bg3a2 Nb3
B. : Ké3 Qé4 Ra6 Pç4
+        (5+4)
The play of the white rook and the black king will remind you of the Köko!

The next one is not very interesting, so you don't need to look for it.
3 - White to play and draw
W. : Kh5 Rg6 Pé6
B. : Kh8 Rç8 Bd6 Nd2 Pd7
=        (3+5)


Master's words

Three years ago we submitted a Czech 2# helpmate with 6 solutions, implying that it would win first prize. It has now done so. Here it is again. We also spotted the one that has just been awarded the second prize. Could it be that there are good judges after all? 
A small test that was proposed this summer: the position is Kh2, Qh3, Rh1, Bg1 & g2, Pf2, f3 and g3 (all white). Without leaving the f1-f3-h3-h1 square, the White King must go to f1, without passing through the g2 square. Once this is done, the other figures must return to their initial squares. How many moves? Don't rush to the solution, it's really up to everyone. You don't have to do it blindly, like Manuel Apicella. 

Tribowski 1A small sample (to be continued) of the World Solving Championship. Paradoxically, the easiest of the "multi-move" section (4 moves at least) was the 6#. We leave the solution near the diagram but... don't look at it. The helped 3# tortured, for a solution at least, the new world champion, K. Piorun, a student of Murdzia who was just out of the... World Junior Normal Chess Championship. This is for the fools who think that practicing the problem takes us away from the game and scatters us. 
The 5# helpmate dropped Piorun and Murdzia, while one solution (at least) seemed easy to me. 
A few other problems gleaned this summer, including a 2# that inspired this comment from C. Mansfield: "It is very rare for a problem containing two unprovided leaks to be honoured in a grand tournament, but this is not a drawback here, for the whole point is to find the right way to provide for the said checks. Needless to say, I applaud this statement, tired of hundreds of 2# containing totally unjustified "set plays".     
The 5#, 12# inverses are very easy. Vladimirov's 4# is difficult. 
In the first helped 6.5#, the figure drawn by the wB represents an "8", but the recipient of the work, Mr. Prcic, is "only" 70 years old!

AkerblomThe most interesting study of the world solving championship was by Jindrich Fritz, a regular at the Cours de Saint-Lazare. But another one (by A. Akerblom) was also interesting. The third one was badly chosen, as is often the case in these competitions, because it did not have a clear main variant. We give it as a documentation, although it does not deserve to be presented in the course (and indeed it was not). Its only interest was to bring down the most unsympathetic solver on the planet.
Didukh 2The study decreed "of the year" by the problemists gathered in Italy is much less trivial than last year's. It develops an idea (dating from 1938) familiar to the regulars of our circle, since the "fake-master" always begins his talks (other than Saint Lazarus') with the original version of this study. The last occasion was in Rio two years ago. 
To start the year on a good footing, a move from another planet, in R+N against Q. 

Karpov 3The game of the day shows us a great player in a style that we forgot was his... at the beginning. The variation dreamed by an assiduous participant, double quality sacrifice (RxNe5 followed by RxNh5) exists, with a Bishop sacrifice (18 Rd5?!) but it leads only to a draw. 
See you next Tuesday 11 October. May God keep you and... have a good time. 


The one to come, on the other hand, is, despite its bare material, a mine of resources on both sides.
4 - White to play and draw
W. : Kb8 Pg5b4a2b2
B. : Kd6 Ph7h6a3
=         (5+4)

The last one is closer to the game, so it will enjoy the players
5 - White to play and win
W. : Kb7 Rd6 Ng5 Pa5é5g2
B. : Ké8 Qf8 Pa7f7a6é6
+         (6+6)
There are some obvious moves but also a subtle defensive move, followed by an even more subtle offensive one!
The game of the day is that of a young and dynamic player who will later have a long career at the top.

6 - game of the day
1.e4 c5 2 Nf3 d6 3 d4 cd 4 Nxd4 Nf6 5 Nc3 g6 6 Be3 Bg7 7 f3 0-0 8 Bc4 Nc6 9 Qd2 Bd7 10 0-0-0

For the restoration, we opted for Cameroonian specialities. A change from the ordinary

In the notable absence of Guy, the Master proposed 4 problems

7 - h#2  Anticirce with Rose  3 solutions
Gerard SMITS
Probleemblad 2008 (v)
W. : Kd1 Rg4 Bg6h2 Né6 ROg5
B. : Kh6 Qg3 Rç5a4 Bd6 Pa7f7f6
h‡2 (6+8) C+
Anticirce : the capturing piece is reborn on its native square (the promotion square for a fairy piece) if it is free, otherwise the capture is illegal
h=Rose Knight extended in an arc. Without the pf7, one could play Rog5 g5 via f7 - d8 - b7 - a5 - b3 - d2 and f3

Very fun to unravel

The following one is quite exciting with a lot of effects

8 - hs#3 Eiffel Chess with twin
Probleemblad 2008
W. : Ka1 Qé7 Rb1g1 Bç1 Nh6 Pd4f3a2é2h2
B. : Kf4 Pa5g5a3d2g2
hs‡3 (11+6) C+
b) Bb1
Eiffel Chess a piece paralyses an opponent's higher-ranked piece by observing it

Very sparkling

We change category with the penultimate

9 - s#9 Anticirce
Probleemblad 2008
W. : Ka6 Qb5 Rf3 Ba5 Nd6g1 Pa7b6f6h4g2
B. : Kf1 Bé8 Nh1 Pb7d7f7h5é2
s‡9 (11+8)

on 1.Rf2? N×f2(Nb8) 2.K×b7(Ke1)‡, it is white who mate.
So you have to find a subtle manoeuvre to eliminate Fe8 without breaking anything.

The last one is very elegant

10 - h#2,5 Transmuted Kings
W. : Kh3 Pb7
B. : Kd4 Qç2 Pé5ç4
h‡2,5 (2+4)
Transmuted Kings : a King in check catches the march of the piece that puts him in check for the duration of his half-move

This problem produces a very beautiful aesthetic sensation

This concludes this first report of the season.
Good reading to all.

Yours sincerely

Le greffier 

shaved Chinese

Since the diagrams in the report are in Chinese, I merely checked the notation given below, which seemed correct.
When the pen "goes silent" there is 20...Bxg4 21 Qh2! with equality.
It was played 29 Qh6+ then Nxg6 but the clerk gives up at the right moment: it's really over.
Have fun and see you on Tuesday.




In Millour's selfmate 9# anti-cire, it is a white rook on a7, not a pawn. The Albionesque diagram was wrong, I think I corrected next to the diagram, which will probably have escaped the master greffier. Next time I will modify the diagram itself. My drawing skills being what they are, one can expect the worst.

Transmuted Kings : 2 solutions
