TRANSPOSITION
ENGLISH OPENING to ALBIN C-G.

White's QP advance attacked Black's K4(e5) pawn.
Black transposes into the Albin Counter Gambit (a rare variation of the Queen's Gambit Declined) by advancing his Queen's Pawn to counter-threaten the White QBP on QB4(c4). White invariably accepts by removing Black's KP. B-Alt.
