"Mastering the French" by Neil McDonald and Andrew Hartley, 1997 American Batsford Chess Library, Figurine Algebraic Notation, Paperback, 192pp., $22.50 A significant segment of today's chess book market consists of opening books, which focus on the theory of one particular opening or variation. Another large portion is made up of instructional manuals, which purport to teach some aspect of the game. "Mastering the French" is unusual in that it combines both approaches by not only explaining the various ideas behind the French Defense, but also offering current theory on the opening's principal variations. As stated in the Preface by the authors, British masters Neil McDonald and Andrew Hartley, "Unless the deluge of theory is stemmed by Fischer's suggestion that pieces be shuffled at the start of a game, it will always be necessary for the serious player to combine his knowledge of strategical and tactical themes with some memorising of opening variations." The book consists of an Introduction, ten chapters of material and an Index of Variations. Included are 40 complete master-level games, mostly from the 1980s and 1990s, but only one from as recent as 1996, the theoretically important Adams-Dreev game (more on this later). Chapters cover the following material: Chapter 1, titled "Advance Centre", examines the Advance Variation, which occurs after 1 e4 e6 2 d4 d5 3 e5; Chapter 2, "e6 weakness vs d4 weakness", looks at the Tarrasch Variation after the moves 1 e4 e6 2 d4 d5 3 Nd2 Nf6 4 e5 Nfd7 5 Bd3; "f4 Central Clamp" covers the Tarrasch Variation with an early f4 for White; Chapter 4, "Classical Centre" looks at positions where White plays an early Nc3; the Winawer Variation, where Black plays Bb4, is the subject of Chapter 5; the Poisoned Pawn line which occurs, for example, after 1 e4 e6 2 d4 d5 3 Nc3 Bb4 4 e5 c5 5 a3 Bxc3+ 6 bxc3 Ne7 7 Qg4 Qc7 8 Qxg7, is covered in Chapter 6; the "Rubinstein Centre" examines positions where Black exchanges his d-pawn for the White e-pawn; the Exchange variation, where both e-pawns are exchanged, is the subject of Chapter 8; variations where Black plays with an isolated queen pawn are covered in the "IQP Centre"; the final chapter offers examples of other lines not included in the previous nine chapters, such as the King's Indian Attack Variation (1 e4 e6 2 d3) or the line seen in Kasparov-Ivanchuk from 1995 Horgen: 1 e4 e6 2 d4 d5 3 Nc3 Bb4 4 e5 b6 5 a3 Bf8. Quoting the authors again from the Preface, "To master a chess opening, it is essential to grasp the underlying strategic and tactical ideas." Thus, each chapter begins by a review of the pawn structure produced by the opening variation, followed by a look at typical strategic and tactical themes that may result. The technique of focusing on pawn structures has been employed as an effective teaching tool by other writers, and is what gives this book its instructional nature. "Mastering the French" is, nonetheless, primarily an opening manual and was evaluated as such by this writer. To determine comprehensiveness of coverage, accuracy of material and inclusion of current theory, Nikolay Minev's "French Defense, New and Forgotten Ideas" from 1988, and John Watson's "Play the French (New Edition)" 1996 version, were used as reference works. Minev's book indicates that the significant variations of the French appear to be the Tarrasch, Advance, Classical, Winawer, MacCutcheon and the Exchange, all of which receive some treatment by McDonald and Harley (M & H). In Chapter 1, a total of 29 pages and five games are devoted to the Advance Variation. M & H focus on the line 6 Be2 Nge7, which is identified by Watson as "the most common move" at this point, although he proceeds to advocate another idea. In the Tarrasch, after 1 e4 e6 2 d4 d5 3 Nd2 Nf6 4 e5 Nfd7 5 c3 e5 6 Ndf3 Nc6 7 Bd3 Qb6 8 Ne2 cxd4 9 cxd4 f6 10 exf6 Nxf6 11 0-0 Bd6, M & H (Game #8, Tseitlin-Schultz, 1992) transpose into the line Watson claims "predominates at the top levels of over-the-board play", 12 Nc3. Although M & H subsequently deviate from Watson, their conclusion that the variation leads to equality is essentially no different from Watson's assessment. Both M & H and Watson cite the line 1 e4 e6 2 d4 d5 3 Nc3 Bb4 4 e5 c5 5 a3 Bxc3+ 6 bxc3 Ne7 7 Qg4 Qc7 8 Qxg7 Rg8 9 Qxh7 cxd4 10 Ne2 Nbc6 11 f4 Bd7 12 Qd3 dxc3 13 Qxc3, referred to as the "Poisoned Pawn" variation of the Winawer. At this point, Watson recommends 13...0-0-0, leading to a small advantage for Black, while M & H continue with the main Black alternative, 13...Nf5, and follow the game Stefansson-Kaminski from 1995, won by Black (Game #21). Both sources also include games with 8 Bd3 which, apparently, has recently become popular again. The inevitable conflict between sources occurs in the Tarrasch Variation after 1 e4 e6 2 d4 d5 3 Nd2 Nf6 4 e5 Nfd7 5 e4 c5 6 c3 Nc6 7 Ndf3 cxd4 8 cxd4 Qb6 9 g3 Bb4+ 10 Kf2 g5 11 Be3 f6 12 Bh3, transposing into Watson's main line. Here M & H suggest 12...fxe5, calling it the "most accurate move order" and offering 12...0-0 as Black's only option (Game #9, p.53). Black eventually lost in the 1991 game Pyda-Likavsky, but missed what could've been a significant improvement on move 14. Watson, on the other hand, only suggests 12...h5, commenting that this "is the most dynamic solution", based on a Tim Harding correspondence game where Black had barely enough compensation for the sacrificed exchange. Of note is M & H's inclusion of a significant improvement in the now-popular variation 1 e4 e6 2 d4 d5 3 Nd2 c5 4 exd5 Qxd5. M & H and Watson follow standard theory with 5 Ngf3 cxd4 6 Bc4 Qd6 7 0-0 Nf6 8 Nb3 Nc6 9 Nbxd4 Nxd4 10 Nxd4 a6 11 Re1 Qc7 12 Bb3 Bd6 13 Nf5 Bxh2+ 14 Kh1 0-0 15 Nxg7 Rd8 16 Qf3 Kxg7 17 Bh6+ Kg6 18 c3 Nd5. At this point, Watson continues with the well-known Khalifman-Gulko game from 1993, which was drawn since White was able to play 19 Re4 and 20 Rg4. M & H, however, cite the more recent Adams-Dreev from 1996 (omitted by Watson), when White improved with 19 Rad1 and won shortly, reversing the assessment of this line (Game #28, pp. 143-148). Kudos to M & H for including this theoretically-important game. All in all, "Mastering the French" is a solid selection for virtually anyone wishing to learn the French, from the novice to, perhaps, even the budding master. Less experienced players will appreciate the instructional tone that permeates the book, while more experienced players will find that M & H have made every effort to incorporate current theory. While "Mastering the French" does not present a comprehensive, theoretical review of the opening a la John Watson, it does offer significant help to the student in understanding how to play the opening and subsequent positions from either side. Towards that end, this is a book that does what others only purport to do: teach an opening. For that reason, this writer considers this work to be one of the best new opening books to hit the market this year.
