by Carsten HansenPaperback: 256 pagesPublisher: Gambit Publications (January 22, 2001)ISBN: 1901983404Following his recent book on 1 c4 e5, young Danish FIDE master Carsten Hansen now provides detailed coverage of all variations arising from 1 c4 c5, including the Rubinstein variation, the Hedgehog and the Anti-Benoni. Each chapter is prefaced with a quick summary indicating the current status of the main variations. Hansen gives lots of original analysis, and his evaluations often differ from general theoretical opinion. Strategies for both sides are also explained very well. The book also has an excellent index which is very important considering the plethora of possible transpositions. An absolute must for English aficionados.
