The Old Benoni starts with 1.d4 c5. The Old Benoni may transpose to the Czech Benoni, but there are a few independent variations. This form has never attracted serious interest in high-level play, though Alexander Alekhine defeated Efim Bogoljubow with it in one game of their second match, in 1934. The Old Benoni is sometimes called the Blackburne Defense, after Englishman Joseph Henry Blackburne, the first player known to have used it successfully.
