Kuljasevic Davorin. 1.d4 Nf6 2.c4 e6 3.Nf3 d5 - Ragozin and Queen's Gambit with 4...a6 for Black

Modern Chess, Opening Databases, 2018.In the second installment of 'Repertoire for Black against 1.d4', GM Kuljasevic suggests an opening repertoire against 3.Nf3 based on the Ragozin Defense (4...Bb4) and Modern Queen's Gambit (4...a6). Similarly to the Repertoire against the Catalan, the idea is to have one equalizing opening system that you would be comfortable playing against strong opponents, as well as one sharp system that you would use to imbalance the game, get your opponent out of his comfort zone, or just get a playable game without much opening theory, hoping to outplay him in the long run. In this database, the Ragozin Defense will have the role of a solid equalizing weapon, while the Modern Queen's Gambit will be the sharp one.
