Every chess player needs a high-quality answer to 1.e4, and there is nothing more reliable than 1...e5. Black stakes a claim in the centre and prepares to deploy his pieces on good squares. The challenge nowadays is to build a robust repertoire without being overwhelmed by the volume of material and continual advances in opening theory. In this book Nikolaos Ntirlis offers the best of both worlds: a complete repertoire against 1.e4, built on sound positional principles, which does not require excessive memorisation. Against the Spanish the author recommends the Breyer System, one of the most stable, computer-proof options at Blacks disposal. The Scotch, Italian, Four Knights and various other side-lines and gambits are handled with the same clarity and efficiency.
