Deletion of Stonewall Attack

Comment: I'll disclose that I am the original author for the article, although it was back in 2005 when inline citations weren't considered so crucial.) Chess has more independent literature on it than all ''Super Mario'' and ''Pokemon'' games put together and almost all serious chess openings have multiple books written about them. Regarding the Stonewall Attack specifically, the opening is not a primary opening at the top level, but it has received a fair amount of coverage, and a look at Amazon shows that there is at least one monograph book devoted to this opening, ''"The Stonewall Attack"'' by Andrew Soltis (1993). In addition, several books devote a chapter to the Stonewall, for example ''"How to beat 1 d4"'' by Rizzitano and ''"Dealing with d4 deviations"'' by Cox. This in addition to the sources cited in the article, so I am quite certain the article is |notable. An ''overview'' of the strategies involved in the Stonewall, and its popularity is appropriate material for an encyclopedia as long as it doesn't get bogged down with specific moves. There are parts of the current article I don't like much, for example "Sample game" (which was taken from the Evans article), but that is not a reason to delete the whole article

Comment: This article is no more a game guide than Sacrifice bunt or Intentional walk. It is about a single strategy that can be used at a single point in a game. As such, it is clearly outside the intent of . The subject has obviously received significant coverage, and book-length treatment is about as good as it gets. Given that NOTGUIDE does not seem to apply as written, there is no policy-based reason for deletion
