It's my case with this English System: despite never having played it over the board, I've already played it in 61 online games, facing Caruana, Nakamura, and Kamsky, among other notable grandmasters. Maybe after so many games, my charm with this line has been a little broken, but the truth is that I don't consider it good enough to be used in the world championship. 4... f8c5  5. f3e5 This is White's only decent attempt, and it leads to forcing play. 5... c6e5  6. d2d4
