Review: Sipke Ernst’s positional 1.d4 repertoire

If you want to improve your chess, you need a repertoire, but developing a repertoire on your own can be tedious. This is where recommendations from GMs can help. In a new ChessBase course, Dutch GM and FIDE Trainer Sipke Ernst has developed a repertoire for anyone who plays or intends to play 1.d4. Christian Hoethe went over the course and came to the conclusion that White can easily “make his/her opponent sweat” with this repertoire.
