The former main line of this opening article arises after 9… fxe4 10. axb4 e6 11. Nc3 Nd5, where in the last 2-3 years a plenty of engine games have been played. Though Black gets some counterchances, move 12. Qg4! still gives White better prospects.

However, a couple of new grandmaster games continued with 9… Nd5, where after 10. Bf3 players of Black introduced 10… Bd7! as the most promising response so far. According to D. Navara – F. Caruana, Saint Louis (rapid) 2017 and S. Volkov – M. Demidov, Sochi 2014, Black has reasonable chances of equalizing in this line.
