march 29 2011

A big delay in the report due to a problem with the greffier's timetable.
The core group was present, as usual, with a problem of the opening of the room, as is also becoming the norm.
To begin with, a little study to warm up the neuron
1 – White to play and draw
W. : Kç4 Rd5 Bç1 Pg7
B. : Kg8 Ra1 Bf3 Pa6ç3
=                              (4+5)
A beautifully executed domination.
For the continuation of the warm-up, a composition with little equipment, but heavy stuff!

2 – White to play and win
W. : Kç8 Qf4 Pg7
B. : Kh5 Qh1
+                              (3+2)
It's hard to believe, but there are 3(!) different promotions in different variants.
And now, the piece de choix. A magnificent study, of which neither the author himself nor the judge has grasped all the finer points! 

Boss's word

Vieira 1Among the helpmates, the one in 3 moves seems easy, but is not (at least, it was not for me). The one in 7 is on the contrary very easy, which is rare, coming from this author.


The 2# contains several false leads, one of which is formidable. The second 3# is a record. The 7# is an excellent strategic problem, in a version improved by the author last year.

A selfmate 4-moves I selected two years ago: Selivanov, who knows his stuff, has just awarded it first prize. In an incomprehensible indulgence, I omitted to delete the solution.

Two twins in traditional retro: a rarity. Of the three PGs, the easiest is... the longest.

A simple study that still hooked a few tenors last summer in Crete. The old and the new: a computer "creation" showing a double underpromotion, but the third variant is from the 19th century!

Vlasenko 1

Ukrainian composers are breaking new ground, taking the top three prizes in the Oleg Pervakov 50th birthday competition, which is hard to beat when it comes to the quality of studies. Here's one that brilliantly demonstrates that computers can be put to good use, which some people ignore across the Channel. It is so profound that the commentator has managed to miss two half-rose windows, one in the thematic try and one in the actual game.

Giving away a piece for a strong free pawn ("passed", they say) is not a new theme. The position is so complicated that both players accumulate mistakes. So does the computer, misjudging the endgames that may arise. But the "moral" is saved: the one who made the play wins. Moreover, this game teaches us the difference between true and false nailing! Note that 27 Qe4, the suggestion of the youngest member of the audience, not only holds, but was more likely to lead to equilibrium than the move played. Also worth considering is another of his suggestions, the lucid 29 Nxa5.

See you in a fortnight, on April 12. God bless you.
And... have a good meal.


PS : Speaking of regalade, I got back in touch with the restaurant so named, in an avenue in the 14th arrondissement named as a famous Soviet agent. Ten years later, it hasn't changed, despite the departure of its televisual former owner to the 6th arrondissement, depriving the remaining customers of his legendary ranting. You will eat well and copiously for 48-50 €, including wine and coffee. Avoid aperitifs, digestifs and other extras that quickly add to the bill. The menu is 32 €. Without a reservation, show up at 7 or 10:30 pm. If you are still hungry, the waitresses are much more appetizing than in the past.

Enjoy this gem of a composition by capturing your time, it is worth it
The game of the day is a warlike struggle for the initiative that will please the combatants on the board.

A fight with many imperfections, but a good fight all the same.

For the dining part, the audience changed address to move a little less far (the Bistrot Cardinet) where we were well received and well fed.
Maître Guy gave us a short composition but he was less productive than usual, busy as he is at the moment producing judgements on problems and not on the problems themselves, but that's only part of it.
Only one problem was presented by the Master, who is busy preparing his trip to Poland for a solving championship, where, let's bet, he will wear the colours of France, but especially those of Saint-Lazare.

a) the position of the diagram
b) shift all the pieces in a column to the left

Anticirce : the capturing piece returns to its initial square if it is free, otherwise the capture is illegal
It is very surprising the effects that one can draw from the shift of a column towards the left
This report is now finished, and it remains for me to wish you a good reading.
The Master's corrections will be forwarded on his return from Poland.
Yours sincerely

The statement of the 3rd study is more sober: White draws. Now, if the overjoyed master-tabellion manages to win, one can only regret his absence from the European Championship (the other). But he is right to insist on this jewel, it is one of the most fascinating positions ever presented in Saint-Lazare. I spoke to some Ukrainians I met in Poland about it, and they looked bewildered, not knowing anything about it. One of them barely knows Vlasenko. Moral: if you want to be informed, come to the Saint-Lazare course!

Game of the day: I persist in thinking, against several listeners, that in the variation after 9 Nxe5, White is not "better" after 19...Bc6 (bxc4?! 20 Ne3), but only a little better.

On 23...Qd5, better is 24 Qxc2.

The comment on 39 is wrong. The move 39 Nxd4 does not deserve a ? but at most a ?! because on 39 Re1, Black does not play 39...Re4? as indicated by the Black player but 39...Rd1!! which wins.

Enjoy and see you on Tuesday 12.
