You're improving which is great. Dont worry about the rate of improvement. Sometimes it will be rapid, other times slow but steady. Occasionally you have to go backwards before going forward, this can happen when learning to apply new ideas. Regarding openings, I'm 1450 and know only the first few moves of the mainline of only a handful of openings so they are not terribly important for beginners and early intermediates. What is important is learning and applying opening principles and what is called 'principled play'. My suggestion is learn about opening principles, study tactics which will also help with undefended pieces, learn some basics of positional play such as pawn weaknesses, open files and weak squares, think about your opponent's plans. This will get you to 1400 at least.
My one month progress
It is great improvement! Keep it up, I agree with MarkGrubb, also look at Gotham chess channel and maybe think about premium membership on chess.com (Here are lessons) or just join a club in your town (they will give you advices). Maybe I can suggest playing longer games for serious improvement - to have more time to think.
Hey guys! I started playing chess roughly a month ago. Before that I had no idea how the game was even played. Now I sit around 800 elo on chess.com with my lowest rating around 450 the first week I started. Is that even a decent progress for a total noob like me? I only play e4 on white and mostly e5 or c5 against white(as 99% of my games start with e4). Is that a good strategy? Can I climb elo with only these openings? Thanks guys!
