The Suetin Variation 8. c3 O-O 9. a3 is one of the sidelines of the Closed Defense of Ruy Lopez. It leads to less explored positions, and is probably an interesting choice for club level players.
The Yates Variation, which occurs after 8. c3 O-O 9. d4, has been extensively explored in recent years. After the principled 9… Bg4, Line 402 deals with all ensuing variations, except for 10. d5, which is covered in our Line 403.
Though Black’s position is equal, it requires quite precise treatment.
