This aggressive counterattacking repertoire covers Black opening systems against virtually every opening except for 1.e4 (plus most flank games) based on the exciting and powerful Tarrasch Defense, which helped bring championships to Kasparov and Spassky. Black learns the Classical Tarrasch, Symmetrical Tarrasch, Asymmetrical Tarrasch, Marshall and Tarrasch Gambits, and Tarrasch without Nc3, to achieve early equality or even an outright advantage in the first few moves.
