KING'S GAMBIT TRANSPOSITION
KGD. (Petrov's Def.) to KGA. (Schallopp Def.)
White developed his KKt to attack Black's KP and aid 4.P-Q4 - still inviting king's gambit acceptance.
Black transposes into the Schallopp Defence of the King's Gambit Accepted by now removing White's gambit KBP with his King's Pawn. B-Alt.
