Hi there! If you're serious about improving, I'd definitely recommend training with a grandmaster chess coach
https://chess-grandmaster.com/ . I took lessons with Valery Filippov from chess-grandmaster.com and it completely changed my understanding of the game. He tailors each lesson to your level — whether you're a beginner or an advanced player — and makes even complex concepts easy to grasp. Every session includes deep analysis of your games, work on openings, middlegame strategies, and endgames. What I liked most is how he keeps you motivated and gives clear, structured homework. The lessons are online, so it’s super convenient, and he uses a digital board that helps visualize everything perfectly. Honestly, if you want real progress, this is the kind of personal coaching that makes a difference.
