april 24 2007

For this session we regretted the absence of Pierre who had left for distant lands and that of Michel who had obviously missed the course step and was perhaps frightened by the size of the "petit chavignol" rib of beef.
The compensation was the surprise guest in the person of Michel Benoit who had not set foot in Saint-Lazare for ages.
As sharp as ever in the variants, he showed that he had lost none of his imagination in front of the chessboard.

For those who don't have the latest news, you will have to wait until May 29 for the next course (and not May 15), and June 5 for the last course of the season which will be magical (on June 12)

The electronic version of the Master is at the end of this email. Thanks to him

To begin with, a little warm-up study where you need to have the necessary composure not to let yourself be impressed.

1 - White to play and make the best of it

Cours2007042401

W.: Kd3, pb6, c6 and h7
B.: Kf8, Qe8, Rb8

A lot of life in this position

The second is a slightly cavalier composition with a more precise statement.

2 - white plays and is forced to make a stalemate move to avoid being checkmated

Cours2007042402

W.: Kg2, Qe5 and f1, Rc3 and h3, Bc1, c5, g1 and h6, pb3 and h7
B.: Ke3, Nd2, d3, d4, e1, e2, e4, f2, g3, g5 and h1

Do you know of a position in which one side is obliged to stalemate (not be stalemated) in order not to lose? There is at least one, discovered by a retro specialist. There is a second one, discovered by the listeners of the course

(see Rusinek's study after the 10th white move). And a third, invented at the table by Daniel, in which the side obliged to pater is in check.


Rudenko 2Heinonen 2

A few problems to last until 29 May (and also as training for Messigny): two rather surprising 2#, three 3# that are not as simple as they seem, an helpmate 4# for Daniel, an selfmate 4# (not really difficult) with multiple sacrifices.


The first study is an amusing one:

so there are studies that can be solved in 2 minutes. The second is inspired by an ultra-famous combination, but there is an instructive flaw, the author having misjudged a final. In the third, by Rusinek, there is not even a final in the usual sense of the word.


An exercise for May: how could Black win and prevent a "fake-master" from being champion of Paris 1979 (several solutions)? Answers on 29 May.


It may seem odd that today's game is included in a book on defence. But Black is forced to act on the kingside as a "defence" against White's action in the "west" and then, in turn, White has to burn bridges, as a normal defence cannot be organised. An "up to the point" game, so to speak. It should be noted that 4...dxe4, "also played recently" according to the great problemist Guy, was played ... once, in an obscure game of 1934: it was yesterday! A revenge -?- on the mistake I had made concerning Von Bardeleben.


All this changes us from the sinister and despairing fable "the turkey and the roquet" which is finishing off the unfortunate French people who still have the courage to follow current events.

 

 

Attention: I have already mentioned the next course, which will take place on 29 May, and will be followed by the fairy tale course on 5 June.


Have a good time

The guy had to suffer for this composition, if only to find the 10 (!) black knights in his favourite shop.

a resourceful position for the 3rd study

3 - White to play and make the best of it

Cours2007042403

W.: Kc4, Bh3, pf5 and h4
B.: Kh2, Nc8, pd4, f6 and f7

The fourth is a full rescue

4 - white plays and does the best (i.e. the least worst in this case)

Cours2007042404

W.: Kf1, Re5, Be1, Nd4 and h6, pb7 and d2
B.: Kh2, Qg7, Rc6, Bb1, pf5

Black has some pretty severe threats that will have to be dealt with virilely.

A little exercise to wait for the 29th of May

5 - White has put Rb4 --> d4 as sealed move, the move goes to Black who can win the game. Instead of the winning move, they played Fxe4 which relieves White and allows him to breathe a sigh of relief and leave with a draw and the title of Paris Champion in his pocket.

Cours2007042405

W.: Kg1, Qg3, Rd4, Bb1, Ne4, pf3 and g2
B.: Kg7, Qe7, Rc6, Bd5, Nf8, pf6, g5 and h6

Let loose on the threats

Today's game is an old-fashioned fight.

6 - game of the day

1. e4 e6 2. d4 d5 3. Nd2 c5 4. dc Bxc5 5. Nb3 Bb6 6. ed Nf6 7. Bb5+ (sweeper's trap 7. dxe Bxf2+) Bd7 8. Bxd7 Qxd7 9. c4 ed 10. c5 Bc7 11. Nf3 Nc6 12. 0-0 0-0 13. Nbd4 NxN 14. Qxd4 Rfe8 15. Be3 ?! (15. Bg5 Ne4 16. Rad1 Nxg5 17. Nxg5 Rad8 and everything is in order for White in relation to the game) Re4 16. Qd3 Rae8 17. Rfd1 h6 18. a3 ? (18. h3) Qg4 19. b4 g5 20. Qc3 Qf5 21. Qd3 Qg6 22. Qb5 Qh5 23. Qxb7 Bxh2+ 24. Nxh2 Rh4 25. f3 (25. Qc7 Ng4 26. f3 Nxh2 27. Rxd5 Nxf3 28. Kf2 Rc4 !) Rxh2 26. Qc7 Rh1+ Kf2 Qh4+ 28. Qg3 Qxg3+ 29. Kxg3 RxR 30. RxR Rxe3 and the greffier's pen was tired, but the white position
is rotten even when your name is Steinitz.

During the meal Master Guy treated us to some of his world premieres, which was impressive.

The Master, between two mouthfuls, presented us some of the compositions he had selected.

For the warm-up, a direct problem, but still with some deviations from the rules.

7 - #2  Transmuted Kings + Rose en b7
Transmuted Kings : the King catches the march of the piece that gives him check
Rose : Extended knight with a circular movement. On an empty board Roe1 can play for example g2, h4, g6, e7, c6, b4, c2 and e1

Cours2007042407

W.: Kd8 Ra1, b2 and d3, Be8, Ng7, pa5, f5 and h4, Rob7
B.: Kg4, pa4, g6 and h6

Caillaud - Lörinc pure juice

A small Heinonen to continue with a light position (especially on the white side)

8 - hs#21
helped selfmate : white to play. white and black cooperate until the penultimate move, after which white plays and black finds himself in a position where he is forced to checkmate in one move

Cours2007042408

W.: Kb8 (!)
B.: Ke7, Bb6 and e6, pb7, c4 and c6

Great art

The rest is a bit harder (like Rammstein)

9 - s#6 Köko
selfmate : white plays and forces black to checkmate
Köko (Kölnischer Kontakt) : at the arrival of the move the piece (or pawn) must be in contact with another piece (or pawn)

Cours2007042409

W.: Kh4 Qf3, Ra3 and e8
B.: Kf1

A little diversions to the Madrasi now

10 - serial h#7 Madrasi 2 solutions
helpmate : Black plays and helps Whites to checkmate them
serial helpmate : black plays n moves in a row to help white checkmate them
Madrasi : Opposing pieces of the same kind that control each other are paralysed.
2 solutions : there are 2 distinct ways to satisfy the statement

Cours2007042410

W.: Kh8, Bf6 and g6, Nd3
B.: Kh6, pc4 and g4

Very cute

To end up with your head turned upside down, we go to the Isardam of the Scottish Caillaud

11 - s#3 Isardam
isardam : it is strictly illegal to put in mutual control 2 opposite pieces of the same nature

Cours2007042411

W.: Kd4, Qg3, Re2 and e4, Bc3, Nc2
B.: Kf1, pc4 and f3

That's it for today.
See you on 29 May.

Sincerely yours

tuft of hair


 

The 10-headed "monster" (position n° 2) also has two PBs on b6 and h4.
Position no. 5: Black certainly missed the win, but did not capture on e4 straight away. He played 41...Qa7 42 Qf2 Rc1+ 43
Kh2 Bxe4. What did they "forget" (several solutions)?

Game of the day: 18 h3 is still uncertain (besides it is not in the habits of the White player) but 18 Nd2! is
certainly better.
Switching error in the commentary 25 Qc7: it is 27 Kf2 Nxf3! (d4! too) 28 Rxd5 Rc4!

Problem 9 : there is a twin : Qf3 in g3 (if I remember correctly).

Bon appétit
