The Ruy Lopez: Berlin Defense, Duras Variation (C65) is a distinct Ruy Lopez variation, defined by the move c4. Historically played by Fabiano Caruana, this system highlights long-term strategic squeezing.
Strategic Context: Instead of the standard Bxc6+, the player opts for c4. It succeeds by maintaining a similar objective evaluation while altering the flavor of the game. This move directly controls d5. Plans should focus on how to prioritize maneuvering and flank attacks and control the key diagonals to exert long-term pressure..
Next Steps: In the resulting middlegame, players must focus on how to prioritize maneuvering and flank attacks.
Data Analysis: Statistical models suggest equality (Eval: -0.09), with a high probability of a draw.
