In the variation 4.e3 0-0 5.Bd3 d5 6.a3 Bxc3+ 7.bxc3 dxc4 8.Bxc4 c5, White continues their development with 9.Ne2 or 9.Nf3. Volokitin, who once ranked among the world’s top 20 with an Elo rating of over 2700, presents his repertoire recommendations for Black against both continuations. "According to my analysis, Black has a comfortable game and can play not only for a draw, but ultimately even for victory if White makes routine moves." Volokitin’s contribution consists of an overview text and four annotated sample games, three of which the Ukrainian GM played himself with Black. In the new free CBM sample, you can view the full article with all the analyses directly in your web browser.
