O-O - Main LineThere are a few minor moves here, but if White notices that the e-pawn doesn't need to be directly defended, then 6. O-O makes the most sense, avoiding a potential pin or check after 6... Bb4, which would allow Black to develop the dark squared bishop and play d6 more easily. 6... Nxe4? in response would be a tactical error, allowing 7. Re1 or Qe2 with a strong attack along the e file, as 7... d5 allows 8. Nxe5 with the c6 knight pinned.Ruy Lopez
