We have completed a huge task of searching and choosing the absolute best (worst?) mistakes that secretly plague most kyu players’ games. Tactical mistakes, strategic mistakes, psychological mistakes — this course will help you get rid of possibly the last remaining shackles that slow you down on your way to 1 dan.
This is a direct sequel to the course Typical Mistakes That Wouldn’t Let Us Get Better.
Suitable for: 10–1 kyu
A huge thanks to: Alexander Dinerstein for helping with examples for the course and Marina Ismail-Akhunova for designing the Nutcracker.


Once of the most helpful courses I've taken. I think it really started to solidify basic ideas like direction of play and finding multi purpose moves. Definitely one I'll come back to watch again. And I'm enjoying looking back over my games from the start of this year with better perspective and noticing many of the mistakes covered in this course!
