I think everyone has had the above situation at one point or another, I myself range from 1100-1300 here on chess.com, I go through long winning streaks and then equally long losing streaks (I am defining streaks as 4 or more wins or losses in a row).
When I find myself in a slump it's usually due to burn out, so I'll do one of two things:
1) Take a break, nothing refreshes the old grey muscle more then rest and relaxation. When I come back after a week or so off I find I am playing sharper then ever.
2) Change my playstyle - I tend to run the same openings for extended periods of time (currently playing a lot of king's gambits) and anyone is liable to start fading out after playing the same way over and over and over again. Find a new opening book you like to play an d run with that for a while.
I began playing 'seriously' back in late March. I broke 1000 about a month ago which, for me, was a great milestone. For a while it seemed that I was winning every game. Really I was probably more like 70% but I was very happy with my play. Felt good.
Lately however, I can't seem to win. It is like I have forgotten everything I have learned!! I have analyzed the situation and I know I was not over confident. But now I have lost all confidence. It is extremely frustrating. I am losing to people in the 600's!!!!!!!!! I am not saying that I should never lose to such people but this is not even funny anymore. Part of me want to give up but I am too stubborn for that.
Has anyone ever had this happen? What did you do? Take a break for a while? Play through it?
Help.
