In 2019, Dubov introduced many new ideas in a rare variation of the Tarrasch Defense, which quickly attracted attention at the top level. Several of the world's best players have tried it, including Carlsen who employed it successfully in the 2019 World Rapid and Blitz Championships. Dubov's double-edged opening system is based around concepts that are suggested by the newer engines, including early h-pawn advances and pawn sacrifices for the initiative. Note that both game annotations are based on work I did for my book, The AI Revolution in Chess. At the top level these days, everyone uses neural network (or hybrid) engines.
