People did not take 1.Nf3 d5 2.e3 too seriously until recently, when online chess started becoming popular due to the pandemic, as this opening was used frequently. I discovered how venomous this opening was when I was trying to find a way to play against it with black, and to my surprise this was not easy. Vincent Keymer uses this opening in a huge percentage of his games and gets great positions and results with them. With this opening, White avoids mainstream theory, and there is more than one possibility for each move. The opening is a mix of positional and attacking elements depending on what system black chooses. I think most club-level players would not know how to effectively counter this opening.”
