The current volume (the fourteenth in the Syzygy Chess Opening Paperbound Series) not only re-examines classical and contemporary opening theory but also explores many new innovations in the middle game of the Center Attack. Primary in the editors' effort was to catalog new ideas and concepts for both White and Black aficionados of the jeu royale.
CLEARANCE - The Modern Center Attack in the Ruy Lopez
The 6 Bc4 variation offers a variety of themes and ideas after 6...e6 7 Bb3 b5. White eyes the sensitive e6 square for possible sacrifices with either Be6 or Ne6 once Black has removed one of its protectors (either by ...Bb7 or by blocking its protection with ...Nbd7 or, in some cases, ...Nfd7).
CLEARANCE - The Najdorf Defense with 6 Bc4
White's early use or abuse of his Kingside pawn structure nearly always dictates the course of action which Black must follow. In the older variations, Black must follow. In the older variations, Black is assured theoretical equality with cautious play. Additional tournament praxis is required to fully assess the complexities of the more recent innovations, particularly the seemingly innocous 4 Nf3 variation.
CLEARANCE - The Advance Variation of the Caro-Kann Defense
Despite its slow honing into maturity, the Arkhangelsk Variation remains a viable arsenal in any tournament player's repertoire.
CLEARANCE - The Arkhangelsk Variation of the Ruy Lopez - Volume 1
This seemingly masochistic yet dynamic reply (7...b5), accredited to international world-class Grandmaster Lev Polugayevsky, is one of the most aggressive moves at Black's disposal. However, this blatant violation of traditional opening principles (six of Black's first seven moves have been pawn moves and initiating flank operations before stabilizing the center), has yet to invoke a clear refutation.
CLEARANCE - The Polugayevsky Variation of the Najdorf Defense
"3 e5 seriously cramps Black's Kingside and, if White succeeds in holding his d4 without any counter-balancing disadvantages, a moment must come when Lady Fortuna will smile upon him; in the form, that is, of an attack with his pieces on the Black King in his constricted position, or else a vigorous onslaught on the pawn chain with f4-f5."
CLEARANCE - The Advance Variation of the French Defense - Vol. 2
The attacking move 6 f4 against the Dragon Defense appeared in tournament praxis over half a century ago. White bypasses the heavily analyzed Yugoslav Attack (6 Be3, 7 f3 and 8 Qd2) and the well-tested Classical Variation (6 Be2, 7 Be3 and 8 00) in favor of immediate complications in the center.
