Trusted teacher: Hello! My name is Daniil, and chess has been a part of my life since I was 5 years old. Passionate about this fascinating game since my childhood, I have played hundreds of competitions, and won dozens of youth and adult tournaments. For 9 years, I have been sharing my passion for chess as a teacher in various environments: clubs, primary schools, colleges, private lessons, associations. I also teach in English and Russian. Furthermore, I graduated from the Sorbonne with a Masters in international strategy and business intelligence. Some figures to know me better: • 9 years of experience in teaching chess • 20 years of experience in club and competition • Official 1900 FIDE / 2400 Elo rating on online platforms • More than 2,500 courses given to 1,000 students in group and individual lessons Whether you are a beginner or an experienced player, my lessons are designed to help you progress quickly while having fun playing. My method is based on solid teaching experience and relies on a comprehensive and structured approach, suitable for all levels. It is based on three main axes: 1. Learning the fundamentals: Learn or consolidate the essential principles in the opening, middlegame and endgames. 2. Tactics and strategy: develop your sense of the game with targeted, fun and practical exercises. 3. Analyze your games: Understand your mistakes, identify your strengths, and apply this knowledge in your games. My goal is to offer you a clear and complete vision of the game, to progress effectively and achieve your goals, whether it is to play for pleasure or in competition.

Lynette
I have taken my first lesson with Lynette and it was a great experience. I have been singing for some time at a choir, but have no formal training and want to learn the fundamental technique, and also work on some of the pieces we sing at the choir. The lesson was very practical, dynamic and she pays great attention to detail. After the class I could feel the improvement on the areas we have covered and felt much more confident on my skills. Highly recommended!

IELTS Coach | Tailored Exam Preparation | General English (Peckham)
Dean
Our first lesson with Dean was productive and an eye-opener. The lesson made me realize there are a few critical areas that I needed to grasp and understand to articulate the IELTS exam preparation. The lesson was fun, and Dean is a good attention detail tutor; he takes time to give a clear explanation of what to focus on. His energy is amicable, and he takes his work seriously. Thank you for the first lesson, and we look forward to our following lessons.

Clases de español como segunda lengua/Classes of Spanish as a Second Language (Seville)
Lucía
Lucia is a very likeable, open-minded and quickly accessible person. We booked 5 conversational clases with her during our stay in Sevilla. Lucia was always well prepared. You can talk to her about any subject. The atmosphere was absolutely relaxed from the very first minute and we had a lot of fun. We can strongly recommend her as a spanish teacher.
