What Is Working Well
Your quiet confidence in complex positions is a real weapon. In the game against yussuf1998 you showed great patience and endgame skill. You turned a cramped structure into a winning one by using active pieces and strong passed pawn pushes, then you converted cleanly. That practical finish is something to trust.
You also keep working after things get equal. The winning game you had as White against bloody_blunder shows a real taste for complications and a willingness to play sharp moves when the position needs them.
Improve Your Conversion Pace
Your biggest practical leak is finishing the game once the material advantage is clear. In your win against bloody_blunder you had a big winning edge, but the game only ended because the clock fell. You can convert such positions faster and better.
- When you are clearly winning, you should trade most pieces. Keep only the pieces needed to support the pawns.
- Bring your king to the center early in a simplified endgame, because an active king wins more pawns.
- Take a few seconds before each move to check if there is a direct way to force a passed pawn from the edge.
- Save at least 4 minutes of clock time for your own moves so you are never flagged while you are winning.
Refine Your Opening Repertoire
As Black you have a compact, reliable set in the Philidor Defense structure. That is a good base, and the results show you are comfortable. As White, however, the English Opening often gives you a comfortable but slow game, and you can lose steam there. Try to give yourself a more concrete plan in the English: choose one central pawn break idea and practice the active development that supressed attacks.
The draw against nattekrant1 is a good case study. In that draw game you kept a healthy position, but a chance for an active central push was exchanged for repetition. Trust your technique a little more in those equal or better positions, and you can turn more of those half points into full points.
