Philidor Defense Albin-Blackburne Gambit (1.e4 e5 2.Nf3 d6 3.d4 Bg4 4.dxe5 Nd7) Chess Puzzles

The Philidor Defense Albin-Blackburne Gambit is a Philidor Defense line where Black accepts a temporary pawn deficit to gain activity and initiative. The defining feature is that Black’s setup follows the Philidor structure (…e5 with …d6 support) while committing to the Albin–Blackburne-style gambit idea—seeking piece activity rather than immediate pawn equality.
