Efim Bogoljubov quotes:

The young people have read my book. Now I have no chance.

When I am white I win because I am white. When I am black I win because I am Bogoljubov

When I am White, I win because I am White. When I am Black, I win because I am Bogolyubov.

To have a knight planted in your game at K6 is worse than a rusty nail in your knee.
