A RECIPROCAL ZUGZWANG PARADOX

A RECIPROCAL ZUGZWANG PARADOX
Gherman Umnov, Podolsk
From EG No. 137 - (Vol.IX), July 2000


The outcome of any position of reciprocal zugzwang hangs on the turn to play. Most of the time study composers strive to carry this through by creating a try in which White, having the move, is in zugzwang, while in the actual solution the same position occurs but this time with Black having the move. Studies have been composed, and not a few of them, where the reciprocal zugzwang is dragged out for several moves, with Black every time lacking a neutral, in fact useful, move. Hm. Let's see if that is always so.
*****************************
U1 Gh. A. Umnov
Springaren, ix 1999



h6e6 0710.11 4/4 Draw
*****************************
U1: 1.Rxb7 Rh8+ 2.RH7 aRxh7+ 3.Bxh7, with:

- Kf7 4.h3! Kf6 5.h4 Kf7 6.h5 Kf6 stalemate, or

- Kf6 4.h4! Kf7 5.h5 Kf6 stalemate again.

In both lines in U1 we see after White's 4th a position of 'prolonged' reciprocal zugzwang.
Now put wP on a2 instead of h2, to create the schema U2, with Black to move.
*****************************
U2 (Gh. A. Umnov - matrix)



h6e6 0310.10 3/2 BTM, Draw
*****************************
U2: After 1...Kf7 we have 2.a4! Kf6 3.a5 Kf7 4.a6 Kf6 5.a7, and it's drawn, while after 1...Kf6 2.a3! and so on, also with a draw.
In U2 it is not so much wB that is paralysed as bR which is excluded from play, having no useful move. Obviously if Black had so much as a single neutral move of the rook without unpinning wB, then White would be winkled out of his draw.
But is this really so obvious?

h5f5 0310.10 3/2 Draw
*****************************
U3: White's choices are bare - he's under the cosh of mate on the move, and his bishop hangs. After either 1..Bc1 or 1.Bf8, Black will give check with his rook, pinning the bishop for ever. Then the white a-pawn will sooner or later become a sacrificial offering. However, in contrast to U2 all the pieces are one rank lower down the board, and this gives the rookm elbow-room for a temporising a move on top of bK's option to oscillate. So there's scarcely anything to choose between 1.Bc1 and 1.Bf8 - they are as bad as each other. Resign, then? Well, with nothing to lose, perhaps something will turn up. 1.Bc1? Rc7! Aha! Black is in no hurry with his check and bishop pin. He's playing cat and mouse, spinning out the agony.
2. Be3 Re7! Now there are two continuations for us to look at:
- 3.Bc1 Re1! 4.Bg5 Rg1! 5.Be7 (Bh4,Rg8;) Rg7! 6.Bf8 Rg8! 7.Bh6 Rg1! and Black wins, or
- 3.Bg5 Rg7! 4.Be3 (Bh6,Rg1;) Rg3! 5.Bf2 Rg2! 6.Be1 Rh2+! 7.Bh4 Rxa2 8.Bg3 Ra1 9.Kh6 Rh1+ 10.Kg7 Rg1, and again Black wins. [A pity that 4.Be3 Re7 transposes into the other line. AJR]
In this pair of try echo-variations Black forces wB to play to the g5 square so that it can be attacked to allow bR to cross the board's equator. But why should Black spurn the pin? Let's take a look at the other first move:
1.Bf8! with:

- Rh7+ 2.BK6 Rh8 (or Kf6;).
What now? 3.a3!! It's a paradox, but here's another position of reciprocal zugzwang: Rh7 (or Kf5;) 4.a4 Rh8 (or Kf6;) 5.a5 Rh7 (or Kf5;) 6.a6 Rh8 (or Kf6;) 7.a7, and this time the zugzwang can no longer be deferred, and it's decisive. Note 3.a4? Rh7 4.a5 Kf6 5.a6 Kf5 6.a7 Rxa7, and Black
wins.

- Rf7 2.Bh6 Rh7. What's this? It's Black's own king that's in the way of the rook's otherwise winning transfer to the southern hemisphere, whereas in the first line it's the white men that rule out the same manoeuvre. 3.a4! 3.a3? Kf6 4.a4 Kf5 5.a5 Kf6 6.a6 Kf5 7.a7 Rxa7 wins. Rh8 (Kf6) 4.a5 Rh7 (Kf5) 5.a6 Rh8 (Kf6) 6.a7, and it's the self-same zugzwang, with Black paying the drawing penalty.

The try 1.Bc1? loses for White because his pawn stays rooted to the subsequently vulnerable a2 square while Black threatens checkmate and harasses the white bishop. In the solution, on the other hand, White paradoxically draws precisely because his pawn is on a2, keeping the tempo-choice (of moving up one square or two) up his sleeve. Curiously, in the tries, whether Black allows the excelsior to run to completion or captures the pawn when it reaches a7 is largely irrelevant, but if he captures on the promotion square a fresh little study (U4) arises.

e4h4 0130.01 2/3 Win
*****************************
U4: 1.Kf3! a2 2.Kf4. We have already met this position in U3, but with colours reversed. a1Q 3.Rxa1 Bg2 4.Ra5! Bf1/i 5.Rg5! Kh3 6.Rg3+ Kh2 (Kh4; Rg1) 7.Kf3 Bc4 8.Kf2
i) Bh1 5.Ra7 Kh3 6.Rh7+ Kg2 7.Rh8 Kg1 8.Kg3 and 9.Rf8.

It's a pity this study steps outside our theme, but U3 in contrast to U2 demonstrates once again that what is obvious is not always the whole truth. Which has to be the credo of every composer.

major changes:
1.31
maintenance release
with Fire 1.2 and 1.3, Totalbases and Triplebases can be configured to autoload on engine startup only via the fire.cfg file, so i've added 2 new UCI options, and associated code, which enables configuration of 'autoloading of Robbobases' via UCI GUIs:
Autoload Totalbases
Autoload Triplebases
id name and id author are now placed outside of 'if
(CfgFound)' statement in static void uci()
this was causing Fire 1.3 to not load in Fritz and CB
Hash size wasn't being read properly if using fire.cfg
this has now been fixed

new/faster bitboard LSB/MSB routines
mutually exclusive fire.cfg/UCI GUI options

About:
my goal with Fire was to combine all the best ideas, features, and strengths from the IppoLit family of releases...IppoLit, RobboLito, Igorrit, and IvanHoe.
in addition i have added all the best ideas that Sentinel and i came up with during the development of Robbolito 0.085g3. with enormous beta testing help from the Decembrists and Robbolito comrades, we posted more than a dozen public betas on Immortal223 during the last four months of 2009
(for details, please see the RobboLito page)

Chess Puzzles: The Art of Zugzwang

The action on the chessboard is in the moves and chess players are eager to make them. But sometimes they would rather stay put, skip a move, go for a walk and never come back. The dreaded word "zugzwang" crosses their mind and they know they are in trouble.
Zugzwang is a German word and, according to chess historians, it was introduced into English in 1904 by the world champion Emanuel Lasker.

What does it mean being in zugzwang? In simple terms, you have to move and you don't want to. Every move you make leads to a worse position and often to an outright disaster. You see it mostly in the endgame, sometimes in the middlegame and never in the opening. It flourishes in chess compositions - in chess problems and endgame studies.

We give three examples of the zugzwang theme. Try to solve them! We will publish the solutions on Monday, June 7.

The first example is a chess problem, in which White mates in two moves. It is attributed to Paul Morphy, an American genius who conquered the chess world in the late 1850s.

White mates in two moves

One clear rule of chess is that king against king, with no other pieces, is a draw. It is still a draw if you add two knights to one side. Or is it? The French poet, novelist and playwright, Alfred de Musset (1810-1857), played chess with passion, fantasy and temperament in the Cafe de la Regence in Paris. He became famous, but not as a chess player.
In 1849 he composed and published a wonderful chess problem that turned the theory about two knights upside down, as if to prove that almost every strategical and tactical rule in chess has its exception. The solution to his three-mover, based on zugzwang, is remarkable.

Alfred de Musset

2010-06-02-AlfreddeMussetD2.jpg

White mates in three moves


The theme of dominating knights appeared in the work of the Latvian chess composer Johann Sehwers (1868-1940), also known as Janis Zevers. He was a prominent linguist and literary historian and his collection of 64 endgame studies, "Endspielstudien," was published in Germany in 1922. Try to find out how white wins in Sehwers's amusing study.

White wins

To all those, who welcomed me back, many, many thanks! We plan to run the column twice a month. Chess puzzles will appear separately every two weeks.

Due finali patti: Donna contro Alfiere e Cavallo

Queen special draw against Knight and Bishop

Imput the following two FEN code here:

http://www.shredderchess.com/online-chess/online-databases/endgame-database.html

This is well known:
FEN:
7k/6b1/8/4n3/8/8/K7/1Q6 b - - 0 1


But this came to me as a real surprise:
FEN:
7b/6k1/8/4n3/8/8/K7/1Q6 b - - 0 1


In italiano: l'Alfiere eunuco, castrato nell'angolo, riesce a far pari con la Donna, grazie al Cavallo...

Da cui potrebbe derivare un simpatico problema, Il N. muove e patta:
Black move and draw
FEN:
7b/6k1/8/8/8/5n2/K7/1Q6 b - - 0 1
