Wikipedia:Articles for deletion/Musketeer chess
Despite all of that, I still have to lean towards delete. We have the |reliable sources policy for a reason; even if something is well-known in chess circles, that doesn't automatically confer |notability unless reliable, secondary sources can be found. Per  the subjects of Wikipedia articles must have significant coverage (i.e. direct and detailed discussion of the topic) in reliable secondary sources (i.e. secondary sources one step removed from the actual subject, and which have some level of editorial oversight). I'm having a hard time seeing that guideline being met here, even the creator himself said that there is only the one article and/or book mentioning it. Even if the notability guideline was somehow met, we can't just publish an analysis of a bunch of |primary sources: that's literally the definition of |original research. Unless additional |independent sources can be found, I unfortunately don't see how this article can be retained in its current form
