It is printed on the end papers of a book on chess by Blackburn, the English chess wizard, probably the most dynamic chess player who ever lived, although he wouldn't get to first base in the cold war type of chess they play nowadays.
Seguru aski sekula izan den xakelari dinamikoena den Blackburn, xakeko sorgin ingelesaren liburu baten bukaeran azaltzen da. Hala ere gaur egun jokatzen den gerra hotzaren gisako xakean lehenengo mailara ez litzateke iritsiko.
