Talk:Chess strategy

Old talk

Hi,

I'm a newcomer here and I'd like to contribute to the chess theory pages! I'm a chess player and teacher and I was wondering if this project could have sense: building a complete free chess encyclopedia! Perhaps it's a too big deal, but Wikipedia is bigger than one could imagine 2 years ago! What do you think? The starting point is choosing a standard for classifying openings (and symbols for evaluation, like +-, =, etc.), middlegame and endings. Then contributors will start editing a specific page (i.e.: Marshall attack in Ruy Lopez, or identified by a code like C90 for instance) simply inserting the PGN game score (with variations). The perfect thing would be using some browser-based tool, like an applet, to show the moves. I hope this could be done, in a future (perhaps not so far). Teutoburgo

Alex, why add origin squares to some of the moves? That's not normal notation, and it might be confusing because it's only done for a few of them and not in general. --LDC

Well, I thought it would be helpful to know where the pieces came from. I reverted. AxelBoldt

Usually the entire sequence of moves is known, or at least the starting position. When the only diagram is the position after the move, I think think it makes sense to include the square of origin. True, it isn't _the_ standard, but is _one_ standard, and a good idea in some situations. --Karl Juhnke

This issue is really a function of who the audience is. (There's a Wikipedia rule about that.) If we intend the reader to be the experienced chess player, then by all means omit redundant origin squares. But it's more likely that the reader will be very inexperienced and fumbly when it comes to reading notation. Including all origin squares is just as "normal" as omitting them. If origin squares are shown they act as a reality check to whether a previous move was made correctly, and they avoid the problem of omitting them when they really aren't redundant. Eclecticology

I just noticed that we have a bigger problem: our diagrams don't show the file letters and row numbers, so that beginners won't be able to read the algebraic notation. AxelBoldt

Karl, your example diagrams are great! For the endgame section, where we say that kings should fight for the squares in front of passed pawns, I'd like to request a diagram of white: Ke5, Pd5 black Kd8. White moves, the only winning move is Kd6. AxelBoldt

Diagram added. I'll leave the spacing, format, caption, etc. to you. My work on this page is convincing me that it is vastly harder to discover/design a good position than it is to make and upload the image. If anyone has any more suggestions, I'll happily make more pictures.

P.S. Kd6 is not the only winning move. Ke6 wins too, e.g. 1.Ke6 Ke8 2.d6 Kd8 3.d7 Kc7 4.Ke7 etc. However, if you back everyone up a rank, i.e. white Ke4, Pd4 black Kd7, then white Kd5 is the only winning move. Should I include that diagram instead?--Karl Juhnke

You are right, the Ke4 position would be much better. Also, I was thinking for the king attack section: a standard bishop sacrifice on h7, maybe in the Colle system. AxelBoldt

ditto about the diagrams. We may be close to spinning off endgames as a separate article. I agree completely with the point that you are trying to make with your example. An even more fundamental point to illustrate and understand yours would be something to illustrate the concept of the opposition. Eclecticology

Actually, the diagram that Karl just added is a nice example of opposition; we just need to cover the concept in the text. Personally, I'm not a big fan of splitting the article into pieces: that way, people have to click around too much and get lost. AxelBoldt

The diagram has been modified. (Interesting how the page doesn't show as modified, because I only overwrote the image with one of the same name.) I'm still taking requests for more diagrams if anyone wants to think them up and compose the surrounding text. --Karl Juhnke

Values Of The Pieces

The "values of the pieces" section is incomplete in one important way. To be sure, there is no significant error in rounding-off the relative piece values (expressed in simplified ratios) as 1, 3, 3, 5, 9 for all of the pieces except the king. Unfortunately, I do not know the proper relative piece value of the king.

There is a popular misconception that the relative piece value of the king, despite its low attack value, is infinite since a game of standard chess can be won by capturing a single, royal piece (to use chess variant terminology). This compelling logical truth is deceptive and ultimately, simplistic. For, nonetheless, programs (by example) written to play chess which ascribed an extremely-high, finite value (as a useful approximation of infinity) to the king in this game achieved less-than-impressive ELO ratings. The reasons can be explained deterministically.

Where the king is given an extremely-high, finite value, the AI player or alert human player will demonstrate a tendency to make unnecessary moves of the king or other pieces to enhance king safety trivially. Essentially, such irrationally-defensive play wastes moves. This works to the advantage of the opponent in development. Typically, this leads to positional advantages, then material advantages and ultimately, the capture of the king for the opponent. One could choke on the irony.

Relative piece values are extremely important to any chess variant (including standard chess). In the case of standard chess, this fact is not so obvious due to opening book theory being so richly developed and catalogued. Strategy and tactics can become chaos, nonetheless, in the absence of accurate and complete information if playing against a competent opponent in possession of accurate and complete information.

There are surely some computer chess experts or people deep into researching this game out there who know a useful, moderate finite value for the king. Not being one myself, your input is much needed.

OmegaMan

There is no logical finite value for the king in chess because it cannot be exchanged for any other piece or any other combination of pieces. The whole point of the game is to checkmate the enemy king. Alex.tan 15:32, 1 Dec 2003 (UTC)

"This value will be completely dependent upon the particular program which is being coded. But consider the following proposition: The King is worth the value of all the other pieces combined.

Thus with the 1/3/3/5/9 value system, the King would be worth 39. A relatively low value but significantly higher than all the other pieces. This will effect the program's move evaluation, givng the piece an aggressive profile. And the look-ahead of the program will take care of potential mating."

L. Lynn Smith

computer programmer & chess variant expert

I think this is an issue for the computer chess article rather than here. In pure chess terms the king really is of infinite value, but when programming a computer, I suppose there may possibly be reasons why you wouldn't want to give it an infinite (or stratospherically high) value (though I admit, I don't see what those reasons would be myself). Either way, this is really a computer programming issue, not a chess issue. --Camembert

Well, it goes against the Turing Test principle to make an arbitrary distinction between rational criteria used by computers and humans. Nonetheless, the difficulties many have with accepting the aforementioned ideas are understandable. I only want Wikipedia to be more incisive and informative than a typical introductory chess text on this important point, to describe the vast theoretical complexities of this game correctly (within realistic limits). Unfortunately, I am at a loss to prescribe exactly how- to give you an exact, authoritative value for the king to publish.

OmegaMan

The secondary source of the 200 point valuation of the king in chess:

chess piece point value

This information was migrated from that long-standing Wikipedia article to this one. The primary source of this value would be known to the Wikipedia editor Siroxo who wrote that article. In my opinion, he/she is probably rational. Please ask him/her about the details, any verifiable citations in the literature or effective chess programs which use this appr. value. You may discover that you need to replace what you have deleted without first investigating. --BadSanta

Thanks for pointing out that article; I didn't know of its existence. I'll raise some points on its talk page. --Camembert

WikiProject, possible move to wikibooks

Hi, A discussion on what should go in a wikipedia article on games is underway at WikiProject Games. The current concensus (by only two users, including myself) is that strategy guides like this page should be moved over to wikibooks. So far, I don't think there are enough particpants to make such wide reaching decisions, so I'm asking for more voices to be heard. The discussion is at the wikiproject's talk page.

Please note that I do not advocate deleting this type of article completely, but feel a chess strategy guide (and strategy guides for all games) fits better with the mission of wikibooks, so this page would be moved over there, and be linked to from the wikipedia article about chess. Premeptive thanks for your participation. Gentgeen 08:03, 14 Jan 2004 (UTC)

Indeed, I think this article should be merged into Wikibooks:Chess. --ZeroOne 16:12, 26 Mar 2005 (UTC)

I'm in favor of keeping it here. Bubba73 (talk), 04:04, 16 May 2006 (UTC)

Zugzwang

Should the Zugzwang page be deleted and entered in here under tactics? I just noticed that Zugzwang had its own page but no mention on this one. kmac 14:58, Mar 6, 2004 (UTC)

It certainly ought to have a mention on this page (thanks for putting something in about it), but I don't see the harm in it having its own article as well for a more detailed look at the subject. It's a pretty important concept, and quite a lot could be said about it - the article as it stands is just a start, really. --Camembert

Piece values (again)

The article sayeth:

There is another system for evaluating chess pieces, as follows:

pawn = 3,1st captured Bishop = 11,2nd captured Bishop = 10,Knight = 10,Rook = 15,Queen = 29.

Using this system, in a B&N trade for a R&pawn (for example, on square f7, after castling), the B&N are worth more (20 or 21 vs. 18 for R&pawn), hinting that this kind of a trade is not equal, and therefore unadvisable. The traditional system indicates that these pairs are equal.

This system seems needlessly complicated to me, and I'm not sure it has very wide currency. Can somebody give an example of a writer who advocates it? If so, lets cite them in the article. If not, I tend to think it should be removed. The fact is that the value of pieces changes with the position, and no simple points system can take account of that. These systems are just a rough guide, and the 9/5/3/3/1 system, which is almost universal, does the job about as well as anything else. --Camembert

I also think this secondary evaluation of piece values should be removed. Although its author considers it refined and more accurate, such systems are argumentative by nature. Furthermore, the writing style is probably confusing to the general reader. Talk where rules and exceptions to rules and exceptions to the exceptions are mentioned (even if they have a basis in fact) should be avoided if at all possible in general encyclopediac articles. --BadSanta

Actually that system has a lot going for it. First, divide everything by 3. That gives:

• pawn = 1
• knight = 3⅓
• bishop = 3⅓ or 3⅔, depending on whether or not you have two of them
• rook = 5
• queen = 9⅔.

That is in very good agreement (always within 1/6 point) with Larry Kauffman's compupter analysis showing:

• pawn = 1
• knight = 3¼
• bishop = 3¼ or 3½, depending on whether or not you have two of them
• rook = 5
• queen = 9¾. Bubba73 (talk), 06:02, 10 October 2006 (UTC)

Beginning quote

Since when did wikipedia articles have beginning quotes? Trevor Andersen 20:45, 3 February 2006 (UTC)

I agree, I'll change it. Bubba73 (talk), 03:59, 4 February 2006 (UTC)

++What is space?++ It isn't defined, and different authors use the term in two different ways. One, is the amount of territory you have marked off with your pawn fence. The other is piece mobility. Both are taken to be important by most authors.

Value of knights and bishops - 3 or 2.5?

Hello - I noticed someone (71.11.170.107) has changed the relative piece value of the knight and bishop from 3 to 2.5. Other chess sites I've visited recently have the queen=9/rook=5/knight=3/bishop=3/pawn=1 valuation mentioned by Camembert above. I hesitate to revert it myself since my knowledge of chess is very rudimentary Lindisfarne 01:07, 16 May 2006 (UTC)

It has been fixed. That was either a vandal or someone who isn't very familiar with chess. Also see chess piece point value. Bubba73 (talk), 04:09, 16 May 2006 (UTC)

Formal tone

The article needs to be comprehensively edited to conform to the formal tone of an encyclopedia. There should not be lines talking directly to the reader ("You should...") - rather this should be an article telling the reader about chess strategy and tactics, not teaching chess strategy and tactics. I know the difference sounds minor, but it should be reflected in the style of the prose. Themindset 22:17, 25 July 2006 (UTC)

I agree. It definitely needs to be fixed. Bubba73 (talk), 02:56, 4 October 2006 (UTC)

Ugh. I took care of the 'you's The Monster 03:55, 17 February 2007 (UTC)

It's not just the "tone" but the content. The bulk of the page is about point values, omitting other factors, like choice of standard/nonstandard opening, black's goal for topological imbalance to make up for white's initiative, and importance of the middle. The problem of the "tone" is merely the the article gives directions on strategy like telling you how to rather than "passively" treating of the topic. Charlespouliot 23:36, 16 June 2007 (UTC)

Actually as far as I can tell this article violates WP:NOT as a game guide. If people want to write strategy guides, they should look at wikibooks, that is a more appropriate place for this article.--Crossmr 15:51, 15 July 2007 (UTC)

Article split

I think this article should be split into two different articles: "Chess strategy" and "Chess tactics". Actually, there is already article names Chess tactics. So, I would suggest the following:

• Move tactics related part into Chess tactics.
• Rename the current article to Chess strategy (now "Chess strategy" is just a redirect to this article).
• Redirect "Chess strategy and tactics" to Chess.

Any comments or objections? Andreas Kaufmann 22:31, 3 December 2006 (UTC)

It sounds fine to me. The only suggestion I have is that rather than redirect to chess, do more like a dis-ambig page: "Go to chess strategy or chess tactic." Bubba73 (talk), 23:53, 3 December 2006 (UTC)

By the way, about 1½ years ago, it was proposed that chess tactic be merged into this article. At the time, I agreed, partly because chess tactic didn't seem to say much rhat wasn't in this article, and the article wasn't very good on its own. Now I am in favor of the split you propose, but the current tactics article will need some work. Bubba73 (talk), 05:15, 4 December 2006 (UTC)

Deletion review

The Deletion Review (DRV) for this article is Wikipedia:Deletion_review/Log/2007 July 16#Chess strategy. Bubba73 (talk), 03:00, 17 July 2007 (UTC)

Misleading title

The article briefly mentions some strategic elements in its first paragraph, and then devotes the remainder of its space to a rather poorly written discussion of the relative values of the pieces. The entire article should be rewritten or deleted. 75.111.197.14 02:27, 19 October 2007 (UTC)

It still needs a lot of work, but it shouldn't be deleted. Bubba73 (talk), 02:32, 19 October 2007 (UTC)

Winning Chess Strategies

I got the book Winning Chess Strategies, and I plan to work on the article guided by the topics in that book, sometime. Bubba73 (talk), 01:15, 7 November 2007 (UTC)

excellent! this article is in pretty bad condition with mostly redundant information, when it should be one of our best. i'm excited for there to be some development! let me know if you need any help MatthewYeager 15:25, 7 November 2007 (UTC)

Off topic?

This article seems to be out of focus. I am in no way any master of chess, but I know that chess strategy is not primarily about piece value or chess openings. What really matters is board domination.

Unlike tactics, which focus on plotting an attack against the opponent’s pieces, strategy is about moving ones pieces to the squares where they later will have a maximum impact on the game. This is usually the same square’s from which they can attack the largest amounts of other squares on the board. The reason for this is simple. The more squares one is able to attack, the harder it gets for the opponent to safely relocate his pieces. He becomes immobilised, while ones own mobility increase. It stands to reason that the one controlling most squares will have more good opportunities in the game since the opponent will have hard to find a square to begin an attac from, or even to find a safe heaven for his pieces or to protect them, once they become the selected target of an attack.

To achieve this domination it is important to create a strong pawn skeleton without weaknesses like doubled, overworked, overstretched, isolated or backward pawns. One should also move pieces to squares from which they have the greatest mobility. Knights (that have only a short range) should be located close to the centre of the board. Bishops will prosper on open long diagonals, and rooks at open or semiopen ranks or files.

I think this article should therefor be rewritten to focus on these importante concepts. —Preceding unsigned comment added by RBM 72 (talk • contribs) 21:06, 27 August 2008 (UTC)

Yes, I noted that the article needed major work last year, and last November I got the book Winning Chess Strategies with the intention of using it as a guide to rework this article. But it seemed like a daunting task, and I haven't done it. It is a lot easier to write about tactics than strategy. Bubba73 (talk), 05:45, 28 August 2008 (UTC)

merge?

I am in favor of the proposed merge of Control of the centre into this article. Anyone have any input? Bubba73 (the argument clinic), 21:53, 1 November 2009 (UTC)

As of now, Chess strategy is 23333 bytes long and Control of the centre is 1136 bytes long for a total of 24469 bytes. If the ideal article is no longer than 32 kbytes long, then we have about 7500 bytes to spare if the two articles are merged. I suppose another question is "What can be written about control of the center?" regarding chess. I'm not sure if there is that much more meaningful information to write about it. If there is nothing more to add about "control of the center", then I agree that it should be merged into Chess strategy. I suppose more could be written about chess strategy, but I'm not sure what. Even if we go over 32 kbytes, it's no big deal. There are plenty of articles longer than 32 kbytes. H Padleckas (talk) 04:43, 2 November 2009 (UTC)

The 32K thing is not observed too much now - it mainly was for some very old browsers. For now, I think it is OK to simply make the control article a section of strategy. Bubba73 (the argument clinic), 05:03, 2 November 2009 (UTC)

The merge has been done. This article still needs a lot of work though. Bubba73 ^{(You talkin' to me?)}, 16:41, 18 February 2010 (UTC)

Defending Pieces

This section seems to have been added in order to make a reference to Nimzovich's theory of overprotection, but it misses the point of OVERprotection: that a key point that is already protected is reinforced, and the overprotecting pieces gain value in their focus and association with this key point. It belittles the theory to suggest that it's just about not hanging pieces. In this sense, Nimzovich's theory of prophylaxis is closer to the mark. --mdamien —Preceding unsigned comment added by 173.162.225.49 (talk) 13:26, 3 June 2010 (UTC)

Rooks

The section on the rooks is very bad. For example it claims that what marks a rook out from a minor piece is that it is able to checkmate with a king. The Gaon (talk) 22:45, 5 July 2011 (UTC)

It doesn't say that. It says king and rook are able to "checkmate an opposing lone king". King and minor piece cannot do that. Ihardlythinkso (talk) 08:30, 6 July 2011 (UTC)

Castling

Before today, this Chess strategy article said almost nothing about castling. I put in a few words on castling under the "King" subsubsection. If anybody wants to take a look at it, go ahead. Also, adding a small section summarizing the role of castling in chess strategy might be a reasonable idea. H Padleckas (talk) 05:19, 20 January 2012 (UTC)

Confused

What does this mean?--

"A bishop always stays on squares of the color it started on, so once one of them is gone, the squares of that color become more difficult to control. When this happens, pawns moved to squares of the other color do not block the bishop, and enemy pawns directly facing them are stuck on the vulnerable color."

Say you sac or trade your dark square Bishop because it's bad and attacks only your own pawns, most of which are on dark squares.

According to the article, moving a pawn to THE OTHER COLOR (squares or pieces?) which in this case would be a WHITE SQUARE, they "do not block the Bishop" (what, the remaining white squared Bishop? YES THEY DO!) and pawns facing them are vulnerable (NO, they would be on black squares and the black Bishop is gone-- according to the article's logic)?
