Pre-order, expected in February 2026. From the preface by GM V. Akobian: I have known Zaven Andriasyan for many yearsas both a close friend and a trusted colleague. We’ve shared countless hours working together, including during the U.S. Championships, where his profound opening preparation, sharp tactical insight, and exceptional analytical skills proved invaluable to my performance. What has always stood out to me is Zaven’s creativity and his genuine passion for teaching. In Andriasyan’s Tactical Workout, he blends his rich practical experience with a gift for clear, structured explanation. The result is an instructive and engaging collection of tactical exercises designed to sharpen calculation and enhance practical play. This book is a true reflection of Zaven’s professionalism and deep understanding of modern chess. I am certain that readers will not only improve their tactical abilities but also find inspiration in the precision, energy, and love for chess that define his work.
