Karel Traxler (1866-1936) was a Roman Catholic priest and Czech chess master best known for the Traxler Variation of the Two Knights Defense. He first played it in 1890. Around 1920, members of the Wilkes-Barre Chess Club (headed by Ken Williams and John Menovsky) in Wilkes-Barre, Pennsylvania started analyzing this variation. Analysis, under the heading of The Wilkes-Barre Variation, appeared in Chess Review magazine in 1934, written by John Menovsky. The opening itself can be traced back to Greco’s time in the 1600s.
