The book was written in 1847 by Agnel and published in 1859 by D. Appleton and Company of New York. The book is 509 pages long. In 1848, he wrote Chess for Winter Evenings. It was later called Agnel’s Book of Chess. Agnel was on the Committee on the Chess Code during the First American Chess Congress. He was a frequent chess opponent of General Winfield Scott. He died in 1871 and is buried at West Point.
