The Two Knights Defence is one of the trickiest tactical openings around. If White initiates complications with either 4 Ng5 or 4 d4, play becomes extremely sharp and gambits and counter gambits abound. Anyone who enters the murky waters of the Two Knights Defence must be well prepared for the mind-boggling complications that ensue. In this book, openings theoretician Jan Pinski guides the reader through both the well-trodden paths of the main lines plus the less fashionable side variations of this most complex opening. Using illustrative games, Pinski studies the key ideas and tactics for both Black and White.
