I suggest improving all stages of the chess game: opening, middlegame and endgame. Study of all chess principles, calculation and the classical study of understanding chess.
I specialize in more advanced level players of at least 1900 Elo

I consider myself a good trainer because I achieved a 2445 rating without a trainer. If I could do it myself, based on my mistakes, then I can help others to improve their game.
I could help many players improve their playing skills. In addition, it indirectly contributes to the improvement of the site chess.com.
I have been coaching for over 10 years. Both children and adults. I have won or become a medalist in many competitions. I have written two books on chess. The first book is called "Playing the Grunfeld" The second book is called "The Modernized Modern Benoni"
