The Weekly Best Grandmaster Games

The Weekly Best Grandmaster Games features 229 decisive games played from 12. October to 19. October 2026, selected from games involving players rated 2500 and above. The collection focuses on games with a clear winner and includes games lasting from 10 to 74 moves, removing very short and exceptionally long games to provide a strong selection of competitive Grandmaster chess games.

Each game can be replayed interactively in MICOS DB Program, where its opening is automatically identified by MICOS Opening Group, Opening Name and MICOS Code. This provides a weekly look at high-level chess while showing how the MasterInChess Openings System identifies and classifies the openings, played by Grandmasters, according to their exact move order.
