Ruy Lopez Yates Bogoljubow 9.d4

Let’s face it. In the King Pawn Closed Ruy Lopez it looks and feels like a waste of time to play 9.h3. My friend Bob Muir liked to play the Yates Variation with 9.d4 as White.

Many played 9.d4 before the Englishman Frederick Yates. He had the distinction of doing well with it against grandmasters. Yates drew both Alekhine and Capablanca with 9.d4. Yates won against Efim Bogoljubow after 9.d4 exd4 at London 1922. When these two met again in New York 1924, Bogoljubow won as Black after 9.d4 Bg4. This became known as the Bogoljubow variation, even though he played both ninth moves repeatedly.

Others tried the line in early games. Emanuel Lasker and Euwe played it was White. Edward Lasker and Rubinstein played it as Black. Capablanca and Thomas both played it from both sides. Prior to all those, Spielmann played 9.d4 vs Marshall in 1911.

As for my adventures, when I had Black against Muir and 9.d4, I chose the Bogoljubow variation 9…Bg4. The bishop pins the f3 knight. This puts added pressure on d4. White’s two most common tenth move responses are 10.Be3 or 10.d5. Bob Muir chose the second move in this game. I combined my kingside threats with capturing queenside pawns. White was down two pawns with two more in danger when he resigned.
