I analyzed some of your games and realized you miss so many tactics and even mate in one
Like in this gameNxg6 was the best move but instead you took the pawn and I see miss a lot of your opponent treat and tactics.
I think u need to work on improving your your tactical vision and also not drop your pieces #look out for your pieces and play more games and you will get used to it
Getting from 1100 to 1400 is not that hard I did in like 2 weeks but getting 1400 to 1500 is the big deal I have been struggling for the past one week but still haven't got it right.
Wish you the best of luck and I think you rush your opening try to enjoy the opening as well and think about your next step cause there are lots of variation and if rush a rare variation you might just blunder it the trick I use for some of my opponents, Good luck.
pls help me
