march 19 2013

With a little delay, here is the report of the last winter session where we looked for various problems (the greffier has a rapping tongue, it is well known).
Still a thin assembly with Daniel and me as listeners trying to counter the Master in great shape.

To begin with, the resolution of the 2 exercises.
1 – exercise 1 White to play and draw
Leonid I. KUBBEL
Shakhmaty v SSSR 1935

7R/2kr3p/6Pp/8/8/6Pr/5K2/8
W : Kf2 Rh8 Pg6g3
B : Kç7 Rd7h3 Ph7h6
= (4+5)

Three helpmates but only one difficult: the last one. A slightly surprising 2#, a very easy strategic 3#, a strategic 4# that has become classic, and finally a 4# with only a black pawn to escort the King: the richness and precision of the game are astonishing.

  
Another foray into the classics: a Rook as strong as two colleagues or R + B + N. 
  
We are starting to get used to the King's moves coming from elsewhere. But this is an inexhaustible field.                 
  
A classic often quoted but always misunderstood anyway. Two great finalists, yes, but endgames are complicated! And all these mistakes do not make less exciting game. 
  
See you, God willing, in a fortnight' time, on Tuesday 2 April. 
  
Enjoy your meal.

1 Kg2 Rh5 2 gh (threatens Rc8+) Kd6 3 Ra8 Rxh7 Ra6+
We notice that there is just the distance
If instead of Kg2 we had played 1 gh Rh2+! 2 Kg1 Ra2 and the continuation 3 Rc8+ Kxc8 4 h8=Q+ Kb7 is convincing

2 - exercise 2 : White to play and draw
Hermann K. MATTISONS

Deutsches Wochenschach 1918
6k1/5R2/1P1c4/8/8/4b1K1/7r/8
W : Kg3 Rf7 Pb6
B : Kg8 Rh2 Bé3 Nd6
= (3+4)
1.Rd7! Rd2 2.b7 Né4+ (2…Nf5+ 3.Kg4 Nh6+ 4.Kf3 =) 3.Kf3 Ba7 4.b8=Q+
free a square for the Rook
4 … B×b8 5.Rb7 Ng5+ 6.Kg4 Rg2+ 7.Kf5
is placed in the net
7 … Bd6 8.Rg7+ ! K×g7 stalemate

3 – exercise for next session :
White to play and win


And finally, the study of the day
4 - White to play and win
Pavel ARESTOV

5b2/K7/8/1k3n2/8/4P1pP/1Pp3P1/3R2B1
W : Ka7 Rd1 Bg1 Pé3h3b2g2
B : Kb5 Bf8 Nf5 Pg3ç2
+ (7+5)
To help you a little, the mandatory introduction is 1 Rc1 Bc5+ 2 K~ Bxe3  Bxe3 3 Nxe3
It is therefore necessary to determine the move of the White King, but first, we must see what happens next!


The game of the day is an old gladiatorial battle from 1911
5 – Rubinstein – Capablanca 1911
1 d4 d5 2 Nf3 c5 3 c4 e6 4 cd ed 5 Nc3 Nc6 6 g3 Be6 7 Bg2 Be7 8 0-0 Rc8

16 Kg2 Rd8 17 Qc1 !!

An exceptional move, the Bh3 holds the whole White strategy at its diagonal end.

Black is still alive

Nd4 becomes colossal
21 ,,, Rfe8 ?!
21 ,,, h5 ! To accentuate the Nd4 domination with g5 g4 to come
22 Bg4 Rd6 23 Rfe1 Rxe1 24 Rxe1 Rb6 25 Re5 Rxb2 26 Rxd5 Nc6 27 Be6+ Kf8 28 Rf5+
28 Rd7 Nb4

28 ... Ke7 29 Bc4 et Rf7 to come
29 Bf7+ Kd7 30 Bc4 a6 ?
Black is probably afraid of the Rook exchange, or of being hindered in the b5 push, but this is not to be feared 30 ... Kd6! is the right move

38 ... Rxa2 !!

After this magnificent variation the clerk drops the pen, exhausted.
You will find the continuation and the end of this beautiful fight in the remarkable electronic version of the Master whom I thank in passing.

To begin the restoration part, a diversion through a new genre  : anti Take&Make
Found on Ouèbe (http://juliasfairies.com/wp-content/uploads/2012/09/bwt2012award.pdf) on the same page as the problem presented by the Master, the definition in English :
Anti Take & Make” definition: every capture ("take") must be complemented by a further step ("make" - not a capture) by the captured piece (Kings excluded), which must move from its square of vanish (according to the wishes of the capturing side in case of options). The capture is forbidden if the captured unit have not possible move. Promotions at the end of the "make" element are normal.

Quite hard to understand but the gemellity of the 2 solutions is very nice.

To finish, a hard-to-swallow dessert

7 - h#2 with neutral pieces Super Circé
Diyan KOSTADINOV

Neutral : Kf6 Pf7g6é2
h‡2 (0+0+4)
b)e2->g5
neutral piece :  can be played by either side
Super-Circé :

a captured piece is reborn on a legal square which is at the goodwill of the taker

A good digestion is to be excluded!

This textual report is now finished.
Good reading to all and see you on April 2nd

Yours sincerely

The master clerk made me appreciate "rap" for half a second. Quite a feat.
 
All this to say that I don't have much to say, only trifles.
 
After 14,,, gf 15 Rc1 (game of the day) it is Rcd8.
 
The 16th move of the game is also ...Rcd8.
 
On 20 Qa4! (Rad1 threat) there is no ...h5??. It's elsewhere.
 
After reflection, I even dare to give 20 Qd3 a real "?", unlike Kmoch's "! Same remark for 38 Bd5? Basically, this historical masterpiece is full of mistakes!
 
On 28 Rd7 it is ...Ne5!
 
It is of course 33 Bg8 and not g9! One feels the approach of the meal and the fairy tale. Although the Master Clerk remains stubbornly abstract.
 
Enjoy your meal nonetheless.
