The Psychology of Gambit Chess Openings
| |
(Click here for a PGN file with the five games contained in this article.)
A gambit chess opening involves the sacrifice of one or more pawns, pieces or even a combination of pawns and pieces in the opening part of the game to obtain compensation in terms of better central control, better development of pieces or some other kind of advantage. Playing a gambit chess opening in a chess game requires a different mindset from playing a regular chess opening where no pawns or pieces are sacrificed early in the opening.
1. FEAR
In a gambit chess opening you will more likely be one or two pawns down after playing the gambit. You could even be a piece down such as in the Halloween Attack (1.e4 e5 2.Nf3 Nc6 2.Nc3 Nf6 3.Nxe5). But a lot of players have this fear of being down by one pawn, two pawns or even a piece down in an opening. This fear stems from the endgame where you have this sinking feeling that you will eventually lose the game. As a gambit player you must have faith that your gambit chess opening will win despite being down. You must have faith in your opening preparation.
Fear of your opponent can have a paralyzing effect on you. If you fear your opponent then you are playing at a disadvantage. This could lead to an error over the board at some point in the game. Over the years I have found that emotions get in the way of the thinking process. I have played my best when my emotions are in check.
When I play my gambit openings I usually try for the big attack. I am willing to sacrifice my pawns or pieces for the attack on my opponents king. If you are down two pawns there really is no turning back. A gambit player may hold the endgame a pawn down but if you are down two pawns you will probably not hold the endgame to a draw. You really need to be thinking about winning the game in the opening or the middle game.
At a certain point in the game when you are losing, you need to not worry about losing. I was playing in a Table Tennis tournament and I was down in the third game by the score of 20 to 17 in a 2-games-out-of-3 match and was one point away from losing the match. We each had won one game and were now playing the third and deciding game of the match. I had realized I was now at the point of no return. My opponent needed only one point to win the match and I just said to myself that now I had nothing to lose and played the rest of the game without any fear of losing. I tied the score at 20 to 20 and went on to win that final game by 22 to 20 to win that match. This same mindset can also be applied to playing a chess game.
2. BE PREPARED
If you play a gambit chess opening you should have your lines well prepared before playing a tournament game. One of my Keoni-Hiva Gambit (1.e3 e5 2.Nc3 Nf6 3.f4 exf4 4. Nf3) lines has been analyzed to a forced draw in the middlegame.
Each gambit opening has a set of tactics and also a set of strategy associated with that opening. You should be very familiar with the tactics and strategy that are associated with that particular gambit chess opening.
There are some very standard combinations that you should know. The only way to know this is to study a book on combinations or to study the chess games of Masters and Grandmasters.
I strongly recommend that you develop and maintain a computer chess database of games and analysis on your gambit chess opening. This is so that you can find and make improvements in your particular gambit chess opening. You can obtain a free IBM computer chess database software program called Chessbase Lite from the www.chessbase.com web site. With this program you can maintain your chess database of games & analysis in either pgn or chessbase cbh format. The Chessbase Lite program (and Frit8 Deluxe, Chessbase8 and Chessbase9) has a feature that allows the user to create an opening book from games in a chess database.
The chess web site known as “The Week In Chess” comes out with a weekly update of chess games and chess news from around the world. The web site: www.chesslab.com has a 2 million game chess database which is regularly updated. You could set up your gambit opening position and extract the games that you need. However, you will need to convert the text download into pgn format. The following link is to a web site which has links to other chess web sites with free chess databases of games. This is Lars Balzar’s web site. You could also purchase a CD or book which covers the particular gambit chess opening that you play.
If you do not have a computer then you could keep your gambit chess opening lines on index cards.
3. SURPRISE FACTOR
Your opponent may not be prepared to play against a gambit chess opening. There are three possible outcomes when your opponent is surprised by a gambit chess opening. In an unfamiliar gambit opening position your opponent could spend a lot of time analyzing each move and be down on time whether it is a tournament game or a blitz game.
At the Hawaii International/US Masters tournament in 1998, I had surprised my opponent Arianne Caoli, an up and coming junior player, with the White side of the Deimer-Duhm Gambit (1.d4 e6 2.c4 d5 3.e4). She was about 14 years old at that time but is now an International Master. She thought for 30 minutes on her third move. I used that extra time to do a deep think on a critical moment in the game.

Chess King's Mad Scramble
Chess King's Mad Scramble
The chess game had all the elements of football. But instead of a helmet, the quarterback had a crown on his head and was not guarded by 300-pound massive NFL linemen, but by tiny pawns. The pass-rushers were fast and heavy: the queen and two rooks flushed the quarterback out of the pocket and the scramble began. He could have been knocked down early, but escaped, running beautifully between and around the opponent's men deep into their territory. It was a mad rush, leading to a winning touchdown. When chess imitates life, it may even resemble American football.
The spectacular game was played between the Russian GM Alexander Riazantsev, who coached the former world champion Anatoly Karpov, and GM Sergey Karjakin, a former Ukrainian prodigy who settled in Moscow and now plays for Russia. It was so complicated even the chess computers sometimes hesitated to suggest the best way. How could have two human beings navigate their way through this mess? But they did brilliantly and with vigor.
It was the most dramatic clash at the tournament honoring Karpov in the Russian town of Poikovsky. It finished Sunday and the victory in this game helped Karjakin to share first place with Victor Bologan of Moldova. Both grandmasters scored 7-4, but Karjakin won the trophy on a better tiebreak.
Riazantsev - Karjakin
Queen's Indian defense
Poikovsky 2010
1.d4 Nf6 2.c4 e6 3.Nf3 b6 (The Queen's Indian, attempting to control the center with the Bishop from the square b7, was first worked out by Aron Nimzovich in the 1920s.) 4.g3 (Akiba Rubinstein's answer. White foresees the clash of the light Bishops on the long diagonal h1-a8.) 4...Ba6 (Nimzovich's aggressive idea, shifting the battlefield: Black puts pressure on the pawn on c4 and along the diagonal a6-f1.) 5.Qc2 (Previously considered meek, but the Queen move caught fire after it was connected with a gambit play. The original game Gruenfeld - Nimzovich, Breslau 1925, went 5.Qa4 c6 6.Bg2?! b5, expanding on the queenside.) 5...Bb7 6.Bg2 c5 7.d5!? (A modern pawn sacrifice, giving White some pressure against Black's entangled pieces. After 7.0-0 cxd4 8.Nxd4 Bxg2 9.Kxg2 Bc5 the light Bishops disappear and Black equalizes.) 7...exd5 8.cxd5 Nxd5 9.0-0 Be7
10.Qe4!? (A powerful pinning move, threatening to attack the knight on d5 with 10.Rd1, for example 10...0-0 11.Rd1 Na6 12.Rxd5 Nb4 13.Nc3 Bf6 14.a3 with White's advantage. The previously played 10.Rd1 can be matched by a tactical development 10...Nc6! as Karjakin played against Leko this year in Wijk aan Zee. The point is that 11.Rxd5? loses to 11...Nb4.) 10...Na6 (Planning to fortify the knight on d5 with 11...Nc7. Preventing a calamity along the h1-a8 diagonal with 10...Bc6 runs into 11.Ne5. White gains a bishop pair and has a strong pressure along the d-file. The weaker 10...Qc7 is met by 11.Nh4! Bc6 12.Nf5 g6 13.Nc3! gxf5 14.Nxd5 with White's advantage as in Sakaev - Ekstroem, Budva 2009.) 11.Nh4 g6 (Hoping to prevent 12.Nf5.)
12.Nf5! (Chess magic! The knight sacrifice gives the white Queen space along the fifth rank. In the game Svidler-Karjakin, Sochi 2008, White was pushed back after12.Qe5 f6 13.Qe4 Qc8 14.Rd1 Nac7 and the piece sacrifice 15.Nxg6?! hxg6 16.Qxg6+ Kd8 did not quite work. Karjakin won in 37 moves.) 12...gxf5 13.Qe5 0-0 (After 13...f6 14.Qxf5 White wins the piece back with dividends, threatening a picturesque mate 15.Qh5+ Kf8 16.Bh6+ Kg8 17.Qxd5+! Bxd5 18.Bxd5 mate.) 14.Qxf5 (Threatening to clobber the black King with 15.Be4, White is not in any hurry to regain the piece. After 14.Bxd5 Bf6 15.Qxf5 Bxd5 16.Qxd5 Nb4 17.Qb3 d5 Black has a strong center.) 14...Re8 15.Nc3 Nac7 (The tactical defense 15...Nxc3 16.Qg4+ Bg5 17.bxc3 h5?! does not work. After 18.Qxh5 black is in trouble, for example: 18...Bxg2 19.Bxg5 Re5 20.f4 Rxg5 21.fxg5 Bxf1 22.g6! Qf6 23.Qh7+ Kf8 24.Rxf1 and White wins; or 18...Bxc1 19.Bxb7 Qg5 20.Qf3 Rad8 21.Raxc1 with White's clear advantage.) 16.Be4 (Looking to create chaos around the black King. After 16.Nxd5 Bxd5 17.Bxd5 Nxd5 18.Qxd5 Bf6 Black's pieces are suddenly active and well placed.) 16...Bf6 17.Qxh7+! (White has to continue chasing the black King since after 17.Nxd5 Bxd5 18.Bxd5 Nxd5 19.Qxd5 Rxe2 Black is fine.) 17...Kf8 18.Bxd5 Bxd5 (Forced, since 18...Nxd5? leads to a splendid king's hunt: 19.Bh6+ Ke7 20.Qe4+! Kd6 21.Bf4+! Be5 [21...Nxf4? 22.Nb5 mate] 22.Nb5+! Kc6 23.Rfd1! Kxb5 24.a4+ Ka5 [24...Kc6 25.Bxe5! wins] 25.Qc4! Bc6 26.Rxd5, threatening 27.Bd2+ or 27.b4 mate.) 19.Nxd5 Nxd5 20.e4 (The black Knight doesn't have many good squares.)
20...Nc7! (Aiming to protect the black King from the square e6. White gets a mating attack after 20...Nb4 21.Bh6+ Ke7 22.e5! Bxe5 23.Bg5+ Bf6 24.Qh6!, for example 24...Bxg5 25.Rfe1+ Be3 26.Rxe3 mate; or 24...Nd5 25.Rad1! Bxg5 26.Rfe1+ Be3 27.Rxe3+ Nxe3 28.Qd6 mate.) 21.Bh6+ Ke7 22.e5! (Opening the e-file makes the black king uncomfortable.) 22...Bxe5 23.Qe4! (The only way to continue the assault. After 23.Bg5+ Bf6 24.Rfe1+ Ne6 25.Rxe6+! dxe6 26.Bxf6+ Kxf6 27.Qh6+ Ke7 28.Qh4+ Kf8 forces White to take a perpetual check.)
23...f6 (After 23...Kf6? White accelerates the attack with a beautiful deflection 24.Bg5+!, for example 24...Kxg5 25.f4+ Kh6 26.fxe5 and now white should win either after 26...d5 27.Qg4 Rxe5 28.Rxf7 Qg5 29.Qh3+ Qh5 30.Qd7 Qg6 31.Qxc7; or after 26... Qe7 27.Rf5 Kg7 28.Qg4+ Kf8 29.Raf1 Qe6 30.Qh5 and the attack breaks through.) 24.f4 d5 (Building a protective pawn wall. After 24...Rh8 25.Bg7 d5 26.Qe2 Kf7 27.fxe5 Kxg7 28.Qg4+ Kf7 29.Rxf6+ win.) 25.Qh7+ Kd6 26.fxe5+ fxe5 27.Rf7 Ne6 ( A picturesque position!)
(Is the line of the pawns in front of the black King powerful enough to endure White's assault or is it going to be as porous as the offensive line of last year's Washington Redskins, breaking on the first hard push?) 28.Qg6 (28.Qf5 or 28.Raf1 can be met by 28...Re7.) 28...Kc6 (Attempting to exchange Rooks with 28...Re7 runs into 29.Bg5! Rxf7! 30.Bxd8 Rg7 31.Bc7+ Rxc7 32.Rf1 and White has the edge.) 29.Raf1 d4 (Planning to help the defense by centralizing the Queen on the square d5. Running away with the King 29...Kb5 invites a mating attack after 30.a4+!, for example 30...Ka6 31.b4! Nd4 32.b5+ Ka5 33.Qd3 c4 34.Ra1! cxd3 35.Bd2 mate; or 30...Kxa4 31.Qd3 c4 32.b3+! Kb5 33.bxc4+ dxc4 34.Rb1+ Kc5 35.Qa3+ Kd5 36.Qf3+ Kd6 37.Be3!, threatening 38.Rd1+.) 30.R1f6! (The pin is a big problem for Black. It freezes the knight.) 30...Qd5 (Protecting the Knight, but allowing a tactical punch. After 30...Kd5 31.b3 b5 32.Qh7 Qc8 33.Rd7+ Kc6 34.Rff7 White wins.)
31.Rxa7! (The Rook is tabu and the black King is now being rushed from both sides.) 31...Rad8 (After 31...Rxa7 32.Qxe8+ Kd6 33.Bf8+ wins.) 32.a4!? (White has the desire to control as many squares as possible around the black King, but it seems that 32.Bf8!, threatening to complete the siege of the knight with 33.Be7, was much stronger. After 32...Rxf8 33.Rxe6+ Rd6 34.Rae7! White should win, for example 34...Rxe6 35.Rxe6+ Kd7 36.Rxb6 d3 37.Qg7+ Rf7 38.Qxf7+ Qxf7 39.Rb7+ Ke6 40.Rxf7 Kxf7 41.Kf2; or 34...Rfd8 35.Rxd6+ [35...Qxd6 36.Re6!] Rxd6 36.Qe8+ Rd7 37.Qc8+. The powerful 32.Qf7 also leads to victory.) 32...c4 (Black could have made it more difficult with 32...d3 33.Qf7 Qd4+ 34.Kg2 Kd6. Imagine the despair on White's face after 35.Qc7+ Kd5 36.Qb7+ Kc4 37.Qxb6 Qd5+ 38.Rf3 [38.Kg1? is even worse: 38...Rb8 39.Qa6+ Kb3 40.Qa5 Nf4!! 41.Rb6+ Ka2 and Black wins.] 38...e4 39.Qb5+ Kd4 40.Be3+ Ke5, seeing that the black King in the middle is safe. And who would guess that the innocent-looking King move 35.Kh3! seals the win.)
33.Qf7? (Chess is a confusing game. Why the same move that worked wonderfully on the previous turn suddenly doesn't cut it? Because White could have woven a mating net with 33.Bf8!, controlling the dark squares and threatening - to confuse you even more - 34.Qf7! and 35.Qc7 mate. Black does not have a good defense, for example 33...Rxf8 34.Rxe6+ Rd6 35.Qh7! [Not 35.Qg7? Rf1+! 36.Kxf1 Qf3+ 37.Kg1 Qd1+ 38.Kf2 Qd2+ 39.Kf3 Qd1+ with perpetual check.] 35...Qxe6 36.Qb7+ Kc5 37.Ra5+! Kb4 [37...bxa5 38.Qb5 mate] 38.Rb5+ Kxa4 39.Qa6 mate.) 33...Kc5! (Running for life! The scramble begins) 34.Bd2 (It seems that 34.Rc7+! is the right way to go, for example 34...Nxc7? 35.Qxc7+ Kb4 36.Qxb6+ Kxa4 37.Qa6+ Kb3 38.Qa3+ Kc2 39.Rf2+ Kb1 40.Rf1+ Kc2 41.Rc1 mate, but and after 34...Kb4! White has to find 35.Re7! with winning chances.) 34...c3 35.Rc7+?! (The simple capture 35.bxc3! is much better, for example 35...dxc3 36.Bxc3 Kc4 37.Be1 Qe4 38.Rc7+ Kb3 39.Rc3+ Kb2 40.Rf2+ Kb1 41.Rb2+! Kxb2 42.Qf2+ and White mates.) 35...Kb4 (The luck is slowly turning in Black's favor.) 36.bxc3+ (White could have tried to bring the Queen back with 36.Rxe6!? Rxe6 [36...Qxe6 37.Qf1!] 37.bxc3+ dxc3 38.Bxc3+ Kxa4 39.Qf2 with chances to equalize.)
36...Kb3?! (Can the black King find a better hiding place after 36...dxc3! 37.Bxc3+ Ka3? The bishop sacrifice 38.Bb2+! may lead to a draw, for example 38...Kxb2 39.Rf2+ Ka3 40.Rc1! Qe4 41.Ra2+!! Kxa2 42.Qf2+ Kb3 43.Qxb6+ Ka2 [43...Ka3 44.Ra1 mate.] 44.Qf2+ Kb3 45.Qb6+ with a perpetual check.) 37.c4! (Better seems 37.Qg6 d3 38.Rcf7, but the shocking 38...Nf4! opens up the white King and Black wins.) 37...Qd6 38.Rb7 (Too slow. White should have tried 38.Rxe6!?, for example 38...Rxe6 39.Qf1! Kc2 40.Rf7!, forcing a perpetual check after 40...Kxd2 41.Rf2+ Kc3 42.Qc1+ Kb4 43.Qb2+ Kxc4 [43...Kxa4 44.Rf1! wins] 44.Qb5+ Kc3 45.Qb2+ etc.; or 38...Qxe6 39.Qf3+ and Black has to be careful since after 39...Kb2?! 40.Qd1 Qg6 41.Bc1+ ! Ka1 [or 41...Kb1 42.Rc6! Qxc6 43.Qd2 and 44.Qb2 mate] 42.Rf7! Qb1 43.Rf2 and White wins.) 38...d3 39.a5 Qd4+ 40.Kf1 Qe4 (Stepping in with 40...Kc2 is more precise, for example 41.Rxb6 Kxd2 42.Qb7 Rb8; or 41.Rf2 Qe4! 42.Bh6+ d2 and Black wins.) 41.Kg1 (After 41.Rxb6+ Kc2 42.Rbxe6 Black wins with 42...Qh1+ 43.Kf2 Qxh2+ 44.Kf1 Rg8! 45.Rf3 Rdf8 46.Qxf8 Rxf8 47.Rxf8 Qh3+, picking up the Rook on e6.) 41...Kc2! (The King turns into a powerful attacker and decides the game.)
42.Rxb6 (It is too late for 42.Re7 Rxe7 43.Qxe7 Kxd2 44.Rxe6 Qd4+ 45.Kg2 Kc2 46.Qh7 Kc3; or for 42.Rf2 Rf8! 43.Bb4+ d2 44.Bxf8 Rxf8 winning.) 42...Kxd2 43.Rbxe6 Rxe6 44.Qxe6 Kc2 45.c5 Qd5! (A simple winning solution, preventing the white Queen from going to a2. The d-pawn just rolls down.) 46.Qg4 (Black wins either after 46.Qf5 e4 47.Qf1 d2; or after 46.Qxd5 Rxd5 47.a6 Rd7 stopping the white pawns and promoting his own.) 46...Qd4+ 47.Rf2+ d2 48.Qf3 e4 49.Qf7 Kc3 (White can't stop the touchdown 50...d1Q.) White resigned.
The game would make a great addition to Colin Crouch's new book "Modern Chess: move by move," published by Everyman Chess http://www.everymanchess.com/ last year. It is a well-written collection of 33 brilliant games, played by some of the best grandmasters in the world. It is another of Crouch's gem - 400 pages of great analysis and wonderful text.

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: 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?

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.

| 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) |

Welcome back, Kavalek !
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.
Paul Morphy
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
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.
