Hello everyone! My name is Derek O'Connor and I am a National Master from California rated around 2300 USCF. Starting from 1800 USCF in early 2016 with little tournament experience, I progressed as a player largely due to structured hard work and practice. I can help students build a strong opening repertoire, annotate games, and improve their tactical vision and positional understanding. If you are interested in online lessons, feel free to send me a message.
I mostly come on chess.com to play blitz and training games.
