Sometimes I played very bad, the chess rates me only 550.

I really thought sac the rook was not the best idea until... I check the analysis. https://www.chess.com/analysis/game/live/163961448604/review

I'm satisfied to see this. How about you?

I am not Top Chess Army member, but Top Chess educational videos help me a lot. I gained from 850 to 940 in just 4 days, big thanks for educational videos, I hope Top Chess channel grow up more and more.
