The Ruy Lopez: 1.e4 e5 2.Nf3... Nf6 arises after 1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 and falls under ECO code C77. Black develops the knight while creating a concrete threat against the e4-pawn. White can either defend it immediately or, recognizing that the pawn is not truly in danger long-term, simply castle with 5. O-O, which is the main line. Among the direct defenses, 5. d3 is the Anderssen Variation, where the pawn shield on d3 rules out any ...Nxe4 ideas and also revives the threat of Bxc6 dxc6 Nxe5, since ...Qd4 can no longer fork White's knight and pawn. This variation appeals to players who prefer to sidestep the heavy theory associated with 5. O-O. Another option is 5. Nc3, the Tarrasch Variation, developing a piece to defend e4, though White typically plays d3 later anyway after 5...b5 6. Bb3 Be7 7. d3. With 9.9 million Lichess games across all rating levels, it is a well-established opening choice.
