Ruy Lopez Central Countergambit (1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.O-O d5) Chess Puzzles

The ruy lopez central countergambit is a Ruy Lopez line where Black immediately challenges White’s central presence with a countergambit-style pawn sacrifice or concession in the center. The defining feature is the early focus on central squares (especially d4/e4) rather than only developing or targeting the kingside. Because this is a named “central countergambit” concept within the Ruy Lopez family, the exact move order can vary between sources, and I can’t reliably state a single canonical sequence without risking mixing it up with a sibling variation.
