ChessBase is running a summer sale on its Master Class Series from July 6-12. The full 20-volume collection drops to €224.90, a steep discount from regular pricing. If you already own some volumes, individual titles go on sale with discounts up to 33 percent.
The Master Class Series covers openings, endgames, and tactics from top players. Each volume focuses on a specific player or theme, making it useful for players looking to deepen their understanding beyond surface-level preparation. Whether you're filling gaps in an incomplete collection or buying the whole set for the first time, this is the week to do it.
The timing works well for summer study. Many players use July and August to rebuild their opening repertoires and sharpen calculation before fall tournaments. Having access to all 20 volumes gives you a complete library of lessons from world-class instructors without the usual premium cost.
