879 is a beginner. I'm around 1400, and I wouldn't classify myself anywhere above intermediate.
At your level, you're most likely hanging pieces all over the place and falling for simple tactics. If you want to improve, stop playing blitz and play standard length games (at least 15-30 minutes).

No matter what you do in life, part of the fun is knowing you are improving at whatever hobby or recreation you choose. I am just getting back into chess after a long hiatus. I had e very bad accident and can not work anymore. So I spend my days playing classical guitar and chess. So here's my question. I have played about 200 to 300 games in the last month. I like playing Blitz chess better than the 30 minute game. At first I was scared to death to play a 10 minute game and now I am playing 5 minute games. My rating went from 622 to 879 in blitz playing. What does 879 represent as far as my skill level? Am I a beginner, and advanced beginner, and weak intermediate, intermediate, advance intermediate, or I am ready to take on Bobby Fisher ( just kidding). Knowing I am getting my rating higher is a good thing but I have no idea what this means as far as my skill level. Can someone chime in and let me know what my level is considered by my 897 blitz rating. Very soon I will try playing a 3 minute game but that is a bit imtimidating for me at the moment. Thanks everyone for taking the time to answer my questions. God Bless. BobbyD NYC
