That’s correct. Except for one nuance.
It should be: “This line is beautifully refuted by 14.Bh6!!” (Fischer). The reference is not part of the quotation, but it is part of the sentence.
Anyone can post a position from a game, but if the image and text exactly matches another’s post, you should credit the source.

Something to notice: whoever created the post knows the difference between a dash and a hyphen. Less than 5% of people possess this knowledge.
Some light reading on the matter of plagiarism: https://www.chesshistory.com/winter/extra/copying.html
If Rohan Dhore is not reading Chernev’s book, but copied the introductory text from someone who is, it is plagiarism. It does not matter that the text is so simple that no copyright can be claimed.
