The Queens Gambit Declined, Orthodox Variation is an opening choice for Black which will never be refuted. It perhaps has an unjust reputation of being solid and passive, but this all-new ChessBase DVD will challenge that perception. Basing his Black repertoire on the Cambridge Springs variation, Andrew Martin takes you on a tour of classic games, showing how Black may conveniently sidestep the dangerous lines with Bf4, whilst retaining good chances and providing comprehensive coverage of the lines where White captures early on d5. This is a repertoire which will suit all levels of player. Video running time: 4 hours 23 min.
