White is building an attack against Black's KB2(f7).
Black quits the "Épine Dorsale" with an irregular Q-side Knight move to Q5(d4) that purposely violates development principles! A gambit (leaving Black's KP unguarded as bait for a trap) named after Joseph Blackburn (1841-1924), greatest British player of the 19th century. B-Alt.
