Punishing Positional Mistakes Part 1

FM Arne Jochen's Punishing Positional Mistakes course, which offers 99 minutes of premium instruction for 1400-1800 Elo players, is on sale today: https://www.chessvl.com/p/punishing-positional-mistakes/

Arne will be teaching a live online class near the end of this month that will serve as the sequel to this course. We will let you know once registration opens for that but in the meantime, we recommend going through this first part if your chess strength is at least 1400 Elo.
