If you know anything about the history of English chess you’ll have heard of Sir George Thomas (1888-1972), twice British Chess Champion, 21 times All England Badminton Champion and Wimbledon semi-finalist.

But did you know that his mother, Lady Edith Thomas, was also a strong player?

While Sir George was noted for his solidity, Lady Thomas seems, from the evidence of this position, to have had a rather more aggressive style.

In this position she was playing White against Miss Gertrude Field in a correspondence game published in 1897.

She’s already sacrificed a rook for a strong attack. How did she conclude the game in her favour?
