Jan Boekelman has produced you with a playable repertoire out of a somewhat sideline Opening, which nobody dared to touch to make it into an entire repertoire.
Try to expand your knowledge in the 3.c3 variation and go beyond the book’s content Deepen your knowledge in 3.c4 variation and do not play it before you know it well Finally, follow the very strong GM Vladislav Artemiev, who has had a relatively successful run with this opening in rapid online events.
