In this game Kasparov is showing a perfect demonstration of the triangulation technique in order to Zugzwang the white king. To be in a Zugzwang means, any move loses or more generally, worsens your position, and one cannot simply pass the turn and maintain the position. In the diagrammed position, the key idea to spot is that white would be in Zugzwang ...

You can easily construct many such positions. For instance: 4k3/8/3P1P/8/8/3p1p2/8/4K3 w - - 0 1 First to move loses - either by moving a king and allowing the opponent to promote or by losing one (and subsequently next) pawn.

There is the famous Immortal Zugzwang Game, Saemisch vs. Nimzowitsch, where White ended up in a near-zugzwang situation in the middlegame. In the final position, White, even being a Knight ahead, couldn't move a single piece without severe consequences: 6k1/3q2p1/p2bp2p/3p1r2/1p1Pp3/3bQ1PP/PP1B1rB1/1N2R1RK w - - 0 1

Zugzwang positions happen naturally as you work to improve your own position by taking good moves away from your opponent. Eventually, when every move is bad (or useless), your opponent will be in Zugzwang. You'll probably find these positions more often in closed games. Tigran Petrosian was a master at balling his opponents up so they'd run out of moves. ...

There is a lot more to it! Zugzwang lies in the "artistic" side of chess, and as such it requires lots of concentration and study of the position which is time consuming and not always there for us during a regular game. It often demands abrupt and shocking sacrifices so that we then "force" our opponent to make a one and only legal move. This is certainly ...

First the verdict on the posted problem. It has certainly no solution in up to 12 moves (checked by Popeye v4.79). And the author of the Gustav software which specializes in selfmates says that there is probably no regular solution to this problem. Another expert thinks that if White simply captures everything which moves, he can then push bK over to g3 ...

Like Brian Towers wrote, a zugzwang by definition can't be helpful to the recipient, but if we go past the terminology and look at your second question: "white forces black to make a move that gives black an advantage. Is that possible?", the answer is yes. You can even force the other player to checkmate you; there's even a class of chess problems called ...

This is a stunning endgame. It is impressive how Kasparov perfectly used reserve tempi to reach the winning position in the diagram where triangulation is all that remains after Seirawan's 40. e4?? which was the last move of time-control. After this Seirawan is lost. Seirawan annotates this game in his book full of stories "Chess Duels : My Games with the ...

You seem to get the meaning/importance of tempo a bit wrong - it's not about getting back to the old square, it's about losing one move during the process, thus forcing the opponent to make his turn when it puts him in worse situation (this is called Zugzwang). This is especially important in endgames, and you can see some examples in the same wiki article ...

The following are full-point zugzwangs, so both sides are losing if either moved! [Title "Noam Elkies. EG 128, Apr 1998, p.53, 10967 (v)"] [StartFlipped "0"] [fen "8/8/k7/8/K7/RNbn4/B7/1R6 w - - 0 1"] 1. Rc1 Nb2# White: 8 with wRb1, 6 with N = 14. Black: 11 with B, 8 with N, 3 with K = 22. Total-36.

Here are some zugzwang positions which have been shown in answers to earlier threads: 4k3/8/3P1P/8/8/3p1p2/8/4K3 w - - 0 1 First to move loses (posted by GloriaVictis at this question on symmetrical zugzwangs). 8/8/8/3pK3/2kP4/8/8/8 w - - 0 1 The "trebuchet" (posted by Evargalo in the same thread). 3k4/3P4/4K3/8/8/8/8/8 w - - 0 1 Posted by Simon ...

It happens that someone tried to evaluate all 960 positions with an engine. Several positions got a score of 0.00, but none of them offered any advantage for black. Of course, those conclusions are only the evaluations of Stockfish at 40 plies depth. It is a strong hint, but no definite proof, that Black is fine in the huge majority of 960-chess starting ...

Here's a position with all pieces where either side to play loses. Seeing why it's a loss takes some analysis. With Black moving first, White's best plan is to open up the Bishop on f1 pinning the pawn, then Qxa4 checkmate. This happens in most but not all lines. Shredder evaluates the main line as +22, because either Nxc5 or cxb8=Q with leave White up a ...

In all The chess books I've read, "tr├ębuchet" is actually one particular case of a full-point double-zugzwang: the minimalist one you can get, with only one pawn for each player: 8/8/8/3pK3/2kP4/8/8/8 w - - 0 1 This pattern can be translated to 30 different positions, with the black pawn on any square in the b7-g7-g3-b3 rectangle. Whoever is on move will ...

No. If you look up the meaning of "zugzwang" you will see something like Zugzwang (German for "compulsion to move") is a situation found in chess and other games wherein one player is put at a disadvantage because they must make a move when they would prefer to pass and not move. The fact that the player is compelled to move means that their ...

Zugzwang is a situation where every single one of a player's moves loses, but if he didn't have to move then he'd be fine. Consider this position: White King on d5, White pawn on e4, Black King on f4, Black pawn on e5. Whoever's move it is loses. If it's White's move then he must move his King away, and Black takes the e4-pawn. White does not want to move,...

Yes - A king can take two moves to go from e1 to d2 - Ke1-d1-d2 and also one move - Ke1-d2. Taking two moves is called triangulation or losing a tempo. A rook can take two moves to go from e1 to e3 - Re1-e2-e3 or one move - Re1-e3. Taking two moves is called losing a tempo. A knight cannot take one extra move to go to the same destination square.

I would like to add that Zugzwang is critical in endgame theory, for instance here this is a very important case of Zugzwang: Another example here: I explain the basics of zugzwang in my blog post here: http://chesstrainerapp.blogspot.fr/2014/02/zugzwang.html

I think you partially answered the question yourself. I can think of 3 scenarios. In very closed positions like this game of Nakamaura against Rybka neither side may be able to improve the position, forcing players to shuffle pieces around. You might even think of slightly more open position, such as a position with blocked pawn chains and one open file, ...

If you allow promoted pieces in the diagram: The following is a half-point zugzwang. [Title "half-point zugzwang: WTM draws. BTM loses in 14"] [StartFlipped "0"] [fen "3q4/8/4q3/2Q5/k7/8/8/2K4Q b - - 0 1"] 1... Qg5+ 2. Qxg5! Qc4+ 3. Kd2 It is a draw if it is white to move. Meanwhile, if it is Black to move, they lose in 14 moves. Black has 25 moves with ...

If you are in Zugzwang, by definition, there is nothing you can do, because any possible move leads to a disadvantage. Most typically Zugzwang appears in endgames with few pieces, particularly in pawn only endgames where is is used as a very common technique. I believe that if you study pawn endgames you should encounter it very often and get very familiar ...

I have been able to find information for everything asked of. However, I have not found any large surveys, only various snippets. Mutual Zugzwangs This page by Arpad Rusz has several examples, one of which is below, of half point mutual zugzwangs along with some general information about them. [FEN "3K4/P7/P7/8/8/8/R5rp/3k4 w - - 0 1"] As for ...

If you literally mean all pieces, the simple answer would be no, there are simply too many free pieces to move that you cannot enforce a real zugzwang scenario there. Note that, if all pieces are still on the board, it means there hasn't been any promotion yet either. Without capturing, the pawns cannot change their files, and continuing on the same file ...

Is there a solution? I don't think so. If the White queen goes to a square where it can interpose, then Black can just play BxB. If, for example, White tries Qe8-d7 or Qe8-e6, hoping Black will move his b8 bishop and allow Qc8+, Black can simply not move the b8 bishop. He could instead just move his light-squared bishop next to White's (White's queen ...

Zugzwang, compulsion-to-move, is where a player is forced to disadvantage their position, or obscure their strategy, tactics, or attacks by moving. Example #1 8/8/8/3pK3/2kP4/8/8/8 w - - 0 1 In this position each King aims to protect its pawn, but if it's white to play, white is forced to move away since the pawn's movement is restricted and c6 is ...

I may be missing something, but it seems that white needs their bishop to be on c6 and their queen to be on h8. If one of these is accomplished by changing the setup of the problem, then the other can be accomplished through white's move.

I don't know any book that has a chapter or even a long section devoted specifically to zugzwang (of course that doesn't mean one doesn't exist) but the concept is pervasive throughout any book about endgames. I think any good endgame book would help; there are books for different levels and tastes, but just to give one example that I have handy, Fundamental ...

In this particular endgame, there are no mutual-zugzwang-positions. An overview over the positions is at http://chess.jaet.org/cgi-bin/mzugs

Losing a tempo and zugzwang are normally endgame terms. All pieces, except the Knight, can maneuver to obtain the same position, ie lose a tempo(same as playing a NULL move.) In this position, Black would lose if it's his turn to move, so White loses a tempo with the Bishop. [FEN "1n6/5p1p/p1p1pP1k/1pP1P1p1/1P1PB1K1/P7/8/8 w - - 0 0"] 1. Bc2 Nd7 2. Bd3 ...
