Experiences from the full paid Opening Mastery course.
“I started playing 9 months ago and bought this course only 4 1/2 months ago, when my Elo rating was around 850. Today - 4 1/2 months later my Elo is almost 1300! ... And most of this progress is due to this opening course!”
“This opening course ... was finally the turning point in 2025. When I started focusing on the essential ideas and moves my rating went up from 1000 to now 1250 on Lichess.”
“Yevhenii doesn’t just teach simple tricks but aims to teach an understanding of the opening, and he also gives ideas on how to transition from the opening to the middlegame with a plan. ... I’ve finished it and now I feel much more secure and confident.”
“The 10-Day Opening Mastery course helped me tremendously by providing a clear, practical repertoire built on understanding rather than memorization. Overall, the course gave me confidence to enter the opening without fear of being out-prepared, and it made studying chess genuinely enjoyable again.”
“I was below 300 and started using the opening for black that is taught in this course. I have improved to 447. I still have a long way to go but I have learned so much!”
“I remembered that against the Stonewall you had said that you had to attack on the woman’s side. Yesterday I did it in the game against a 1761 Fide and I won in 30 moves!”
