| B 12: Caro-Kann Defence, The Advance Variation Sasa

| Before the nineties, The Advance Variation of the Caro-Kann Defence was a system where White was striving to positionally maintain a slight advantage due to a favorable central pawn structure, without a risk of allowing Black any counterplay. Nowadays, there is a palpable change in the way things happen in this highly fashionable opening (although it seems that the pendulum of popularity has of recently swung the other way towards the 3. Nc3 lines), as the computer analyses inevitably led to wondrous transformations of the critical lines. White players were the first to take advantage of such developments, using the opening preparation as a means of fetching them easy points by the handful. Naturally, it eventually began to work for both sides, and White could no longer safely take the sting out of Blacks attempts to not surrender tamely. Given the above reasons, Chess Informant Editorial Board has decided to do an encore after a gap of ten years from Seirawans outstanding work on the first edition of the B 12 Monograph. The purpose of the new monograph is to offer a detailed up-to-date coverage of the B 12 lines without unnecessary overlaps with the previous edition. Without displaying a bias towards one side or the other, this article previews adventurous twists and turns that may arise in the 1. e4 c6 2. d4 d5 3. e5 Bf5 4. Nf3 e6 5. Be2 c5 6. Be3 Qb6 line. The analytical work flowed from my keyboard with great ease and pleasure, and I hope that it will bring the readers at least an inch closer to the truth. |
