Bologan, Victor: Bologan's Black Weapons in the Open Games (PB)
If you are ready to play the Ruy Lopez with Black, you also need to be prepared if white avoids the Ruy. In this book Victor Bologan covers all relevant lines with a well laid-out, clearly explained and eminently playable set of responses.
But this is not just another chess opening repertoire book. Bologan presents TWO different options against every main line: a common sense approach and an aggressive weapon. It's actually two books in one!
And there is more: help for those who are new to 1...e5 and in a hurry, a wealth of new ideas in old lines, The Fast Lane repertoire in every chapter (the minimum you should know), a special strategy section: how pawn structures define important themes, transpositions and move-order subtleties: clearly identified, historical lines and gambits re-examined, traps & tricks: visually marked, many examples from Bologan's own games, 2200 game referenced and presented in a separate index, lots of practical tips.
Victor Bologan has taken the chess opening repertoire book to a next level. He has created a unique instrument of chess instruction for players of almost every level.
