After watching your chess games, I realized that you are not playing the opening repertoire, perhaps you don’t have opening repertoire.
Before going to my suggestions, let’s watch one of your chess game.
Opening Suggestions:
In above chess game, you did not play Bishop opening the correct way, although I am recommending Bishop Opening for many users.
The main plan in Bishop opening is to attack on the king side. So when you play your next chess game please keep this plan in your mind.
In some other chess games, some time you play Viena game and sometime you just play random moves, I don’t know what’s the reason behind it.
Perhaps, you do not have an opening repertoire, but if you do have the opening repertoire, please stick to it, until you get 1500 rating.
Let’s watch one of your chess game with black pieces. Flip the chess board for better view.
I am afraid to tell that you have played very terribly, believe me. Please learn proper setup before playing. At your level, play easy openings like Scandinavian Defense or Caro Kann.
Against D4, play d5 and also learn Nimzo Indian, which will help you learn strategical chess.
Middlegames Suggestion:
In the middlegame, you have only two plans, please remember this, number one is to create a plan and find weakness and second is how to create weakness.
Endgame Suggestion:
Learn how to create a passed pawn and also learn basic rook endgame positions.
Conclusion:
In the opening, learn bishop opening and with black learn scandinavian defense. In the middlegame and endgame, learn how to play with pawns.
