Please expand the lead to conform with guidelines at Wikipedia:Lead. The article should have an appropriate number of paragraphs as is shown on WP:LEAD, and should adequately summarize the article.[?]

There are a few occurrences of weasel words in this article- please observe WP:AWT. Certain phrases should specify exactly who supports, considers, believes, etc., such a view.

might be weasel words, and should be provided with proper citations (if they already do, or are not weasel terms, please strike this comment).[?]
Watch for redundancies that make the article too wordy instead of being crisp and concise. (You may wish to try Tony1's redundancy exercises.)
Vague terms of size often are unnecessary and redundant - “some”, “a variety/number/majority of”, “several”, “a few”, “many”, “any”, and “all”. For example, “All pigs are pink, so we thought of a number of ways to turn them green.”
As done in WP:FOOTNOTE, footnotes usually are located right after a punctuation mark (as recommended by the CMS, but not mandatory), such that there is no space in between. For example, the sun is larger than the moon [2]. is usually written as the sun is larger than the moon.[2][?]
There is one 'citation needed' template on the page. Should be fixed or otherwise that line has to go.
Review by SyG: conclusion was "Oppose", suggested for GA-class
Oppose for most of Voorlandt's reasons, and specifically some lack on precise references, for example:
the Note 1 claims sentences like "Most historians consider..." and "Morphy is considered..." which are not referenced.
the sentence "According to his uncle, Ernest Morphy, no one formally taught Morphy how to play chess" shall be referenced (maybe even the whole paragraph).
the sentence "By the age of nine, he was considered one of the best players in New Orleans" shall be referenced.
the sentence "Löwenthal and Anderssen both later remarked that..." should be referenced
also, some links include redirects, it is better to do direct links
the list of "Notable chess games" does not give any positionnal game, which seems in conflict with what is told in the section "Morphy's chess play"
