Great professional, very sharp and lots of knowledge. perfect teaching and learning approach. Еxplains everything easily and comprehensibly. Highly recommended!

I recently had the pleasure of taking chess lesson, from the very first lesson, it was clear that he possessed a deep passion for chess. He has a remarkable talent for simplifying intricate strategies and tactics, making them accessible for me. This helped me grasp the fundamentals of chess more effectively also allowed me to expand my knowledge.

A very knowledgeable and most importantly patient coach. I would highly recommend.

Bestcoach provided excellent and detailed feedback on our chess game. We thought his analysis was spot-on and very helpful, and it included various ideas as well. Their communication was friendly yet professional. Given the unbeatable price point and very quick work, we are happy to recommend their services to any potential buyers. :)

He has a great attitude and passion about chess. Gets me excited to to get better!

Bestcoach gave a coaching experience I would value at well over the price he's advertised at. He is a hidden gem. We went over an otb tournament game I played and he was able to provide me with super detailed and insightful feedback on each move I played. His skill level and knowledge of the game is superb, and I would recommend him to anyone I know who plays Chess.

Highly recomended!! I liked his approach to teaching the game, very simple but taught me so many fundementals in a way that I actually internalized the knowledge for future use!
