Hi there! If you are looking for an online chess coach, then I will be happy to recommend you a great chess teacher. I have been taking chess lessons online with chess grandmaster Valery Filippov for several months. He is a very experienced chess coach who helped me improve my opening repertoire and increase my rating. Also with the help of our private chess lessons I got my first USCF rating. Many thanks to chess grandmaster Valery Filippov for his help and patience. You can go to this site if you are interested in chess lessons online https://chess-grandmaster.com/
