"Irregular chess opening" seems too judgmental, especially since some of the irregular openings of the past have become widely accepted. Fianchettos, for example, were once condemned as weakening the pawn structure. I suggest renaming it "Uncommon chess opening."  <small><span class="autosigned">— Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[User:Dynzmoar|Dynzmoar]] ([[User talk:Dynzmoar|talk]] • [[Special:Contributions/Dynzmoar|contribs]]) 11:33, 8 October 2012 (UTC)</span></small><!-- Template:Unsigned --> <!--Autosigned by SineBot-->

: They are sometimes called "irregular" in the literature, e.g. ''Comprehensive Chess Openings'' by Estrin and Panov.

:"Irregular" is a term used in chess literature and I don't recommend scratching it in WP. It means "infrequently used" or "infrequently seen", so really that is objective not judgmental. I suggest instead to modify the term def in [[Glossary of chess#Irregular opening]] slightly from "unusual" to "infrequently used", plus add language to the current article giving the chess context meaning "infrequent".

::In keeping with other lists, I propose to change the name to reflect that category. 
::Also, since any non-standard opening could be regarded as irregular, should we refer to "notable" irregular openings (plural)?

::::I see now that a ref to "[[Chess_opening]]" ''does'' actually appear in [[Chess]] (at 4.1 [[Chess#Opening]]), and in turn, [[List of chess openings]], ''does'' get a reference (at [[Chess_opening#See_also]]), then [[Chess_opening#Unusual_first_moves_for_White]] (for white?) in turn points here. A bit cumbersome, though.
::::Could you explain why these lists of openings (popular & unpopular) do not warrant a reference in what would seem to be the parent article? I don't quite follow. (Is it the chess mind at work? Not so relational.)
::::Yes, you may well be right that the "notable" is excessively pedantic; in any case notability would be a prerequisite for inclusion in WP. Searching for a better title, the article seems to contrast (some) irregular starting moves with the more common ones. It's certainly a list!

== Definition ==

The term "Irregular Opening" was used much more often in older chess literature when many openings that are standard today were as yet unnamed, and included openings played by Black as well as by White. It does not have a precise definition but I certainly wouldn't define it as "all openings classified under ECO code A00", as this article seems to do. So the fairly common 1.g3 is "irregular" just because the ECO editors classified it under A00, but the rarer 1.b3 and 1.f4 are not because they're classifed under A01 and A02-03? This definition of "irregular opening" is absurd and is not used in any of chess literature. [[User:MaxBrowne|MaxBrowne]] ([[User talk:MaxBrowne|talk]]) 05:49, 4 July 2016 (UTC)
:{{ping|MaxBrowne}} I was the one who moved it, but I also thought that it might cause problems. OK well move it back if you wish, but it should be noted that it falls under ECO A00, so using that definition is slightly wrong for that case. The lead would have to be changed to "mostly under A00" if this was done. [[User:Mrjulesd|<span style="color:orange;">--Jules</span>]]&nbsp;[[User talk:Mrjulesd|(Mrjulesd)]] 10:49, 4 July 2016 (UTC)
::I'll give the definition of "Irregular opening" from the [[Oxford Companion to Chess]].<blockquote>'''Irregular opening''', in the early 19th century any opening that did not begin with 1.e4 e5 or 1.d4 d5. However, [[Carl Jaenisch|Jaenisch]] said, 'As this distinction is purely arbitrary, and unfounded on principle, we cannot ourselves adopt it. We distinguish all the openings as "correct", or else as "incorrect" or "hazardous".' Since then many so-called irregular openings have become standard play. These and many other openings have acquired names and the term irregular opening has gradually fallen into disuse.</blockquote>So it's an old-fashioned term, and certainly not a synonym for "ECO Code A00".[[User:MaxBrowne|MaxBrowne]] ([[User talk:MaxBrowne|talk]]) 13:15, 4 July 2016 (UTC)
:::OK I've moved it. I still think it is a useful term, despite being open to debate to some extent, like much of opening terminology. [[User:Mrjulesd|<span style="color:orange;">--Jules</span>]]&nbsp;[[User talk:Mrjulesd|(Mrjulesd)]] 17:07, 4 July 2016 (UTC)
::::The issue for me is what exactly this article is supposed to be about and how it should integrate with the rest of our chess opening articles. The original title of the article way back in 2002 was "A00", which though a very specialized jargon term related to a code in a specific reference work did at least accurately describe the article's contents. The evolution of the title has been A00 -> A00 (chess opening) -> Irregular openings (chess) -> Irregular chess openings -> Irregular chess opening. If the article is to be titled "Irregular chess opening" or similar (IMO "Irregular opening" or "Irregular opening (chess)" would be better) then the scope of it must be expanded to reflect the actual historical usage of the term, which in the 19th century included even such now common openings as the Sicilian and French. (See [https://books.google.com/books?id=EmkZAAAAYAAJ&pg=PA540&dq=%22chess+player%27s+hand+book%22&hl=en&sa=X&ved=0ahUKEwjejKvY8drNAhUDoJQKHQhwAHYQ6AEIKDAC#v=onepage&q=irregular&f=false Staunton's chess-player's handbook, page 368]). If the contents of the article actually reflected the title, it would be more of a chess history article than an opening theory article since the term "irregular opening" is now considered more or less obsolete. It would probably describe usage by various writers such as Tartakower, Reti, Alekhine, earlier editions of MCO etc and gradual obsolescence. If the article is specifically to be about the openings designated by ECO code "A00", then it's better off being merged with [[Chess opening]]". [[User:MaxBrowne|MaxBrowne]] ([[User talk:MaxBrowne|talk]]) 23:01, 4 July 2016 (UTC)
:::::Well I really don't agree with a merger. It's a common term in usage in both the real world and in many of the chess articles in the project. i don't know what a merge would do apart from make a long article even longer, and without solving any differences in the actual content.

Read it, absorb it, and trim back some of the crappier citations. [[User:MaxBrowne|MaxBrowne]] ([[User talk:MaxBrowne|talk]]) 18:19, 6 July 2016 (UTC)
:The Chess Informant PDF source is pretty good and can only really be topped by a hardcopy page reference, therefore have removed duplicitous links, like chessgames and chessarch links. It would be nice to see explanations for the names of the lines but I'm assuming that'll be covered (or perhaps already has) on the relevant pages. I dont understand what the Nimzowitsch biography refers to as I don't own the book. I would like to see a quote in the reference to explain the cite. As for the one that has escalated to a complaint, the link should not be here. As per recent discussion on spam relating to WTHarvey, the link shouldn't be in the article. As I explained at the start, the PDF link already covers us on the cite front, therefore I support keeping it off the page. [[User:Jkmaskell|Jkmaskell]] ([[User talk:Jkmaskell|talk]]) 20:51, 6 July 2016 (UTC)
::The reason for all these citations was to show common usage. Irregular openings and ECO A00 are all over the Internet. But I can't convince that this is the case, hence the citations. The book one was to a book, the internet link was merely to the publishers web-site. How can a link to the publisher of ECO be considered a spam link? It is the most important one of all. Also [[wp:OVERCITE]] is an essay, not policy, so holds no weight. The Nimzowitsch biography refers to Irregular openings and ECO A00. chessgames and chessarch are reliable sites. Also the second chessarch referred to irregular chess games, the very bones of this current disagreement.

:::The link went to the page promoting a book for sale. We had this debate before and had almost unanimous agreement that those sorts of links were considered spam. On the point of proving common usage, ECO is duplicated on those sites. The ECO list is fine by itself. We dont need three sites saying the same thing when in reality only one said it, the others copied it. On Nimzowitsch, we really need to see a full citation.

::::Ok well the thing to do is put a ECO book citation but without a link to the publishers website. Simple enough. Believe me when I say it: more refs may well be needed, because they support "common usage" idiom. Removing them may exacerbate the situation. Normally they would not be needed but this is not a usual situation. Comprehensive citation is not normally needed, but look at some areas of dispute and there is considerably more citations needed to halt disagreement.

== Back to the issues - at the risk of repeating myself ==

Before any more edits are made to try to "fix" the article I suggest we resolve the following questions.

(1) What is the article's scope? Is it about "irregular" openings in general, or is it about the openings covered by ECO code A00 specifically?

(2) If "A00", is "Irregular chess opening" an appropriate title, given that many other openings have been (and to some extent continue to be) described as "irregular"?

(3) If "A00", what should the article be called? A00 is a "dustbin" code containing miscellaneous openings. Whether you describe A00 as "Irregular openings" or "Uncommon openings" or "Unusual openings" or "Unorthodox openings" or "Miscellaneous openings" or (as the Russians would say) "Incorrect openings", these are plain English ''descriptions'' of the openings covered by ECO code A00, not commonly accepted ''names'' like "Sicilian Defence" or even well defined technical terms. A plain English interpretation of any of these descriptions would also incorporate openings covered by other ECO codes such as [[Alapin's Opening]].

(4) Why is an article about ECO code A00 even necessary? The article contains little content besides wikilinks. ECO code A00 is already adequately covered by [[List of chess openings#A00.E2.80.93A39|List of chess openings]] and to a lesser extent [[Chess opening#Unusual first moves for White|Chess opening]]. It seems to me the article is redundant, and any worthwhile material not already covered by these articles (which is hardly any) could easily be incorporated.

A large number of unsubstantiated statements have been included [https://en.wikipedia.org/w/index.php?title=Irregular_chess_opening&oldid=730493570]. These maintenance tags should not be removed until these various statements have been improved.

Particularly the section "Unusual responses by Black" seems to contain a [[WP:OR|original research]]. [[User:Mrjulesd|<span style="color:orange;">--Jules</span>]]&nbsp;[[User talk:Mrjulesd|(Mrjulesd)]] 10:29, 19 July 2016 (UTC)
:I reproduced the material exactly as given in the source (chess informant's list of ECO codes). Your "OR" tag is spurious. [[User:MaxBrowne|MaxBrowne]] ([[User talk:MaxBrowne|talk]]) 10:33, 19 July 2016 (UTC)
