Strong opening habits
You clearly have repertoire ideas that work in bullet. Your best results come from pet lines like the Amar Gambit and the Hungarian Opening, and you tend to reach playable positions from your favourite setups. That is a real strength. In the loss against alexander10316, for example, you reached a pawn-up endgame out of the Italian complex, which shows you can navigate the early game well.
Time trouble is the real opponent
Most of these losses happened on the clock, not at the board. You are consistently falling behind on time and then trying to play precise moves with almost no seconds left. That turns good positions into lost ones.
- In the game against alexander10316 you had under one second in a pawn-up endgame. You still had real winning chances, but the clock decided.
- Against parsa13945, your clock dropped to 0.1 seconds during a sharp middlegame, leaving you no time for the final moves.
- In the game against edfeeed, you kept fighting a complicated queen ending but ran out of time just as the position was becoming critical.
Treat time as part of the move. Save seconds in known openings, use premoves for forced recaptures, and when you reach time trouble, choose simple solid moves instead of searching for the perfect one. A practical move now beats a perfect move that you never get to play.
Endgame speed and tactics
The clearest tactical miss was against Omar Toom, where the knight could jump to e6 with check and then capture the rook on d8. That is a classic Knight fork pattern. Even in low time, drilling forks and other common tactics makes these moves automatic.
Your endgame play also needs to become faster. You reached simplified positions with real chances in several of these games, but you spent valuable seconds working out king routes and pawn races from scratch. Practice basic pawn and rook endings on a clock so the key ideas come from memory, not calculation.
One opening to fix
Your record against the English Opening Agincourt Defense is winless in four attempts. That line seems to be giving you trouble. If it keeps appearing, consider meeting it with a setup you already know, such as your King's Indian Attack structure, instead of improvising in the middle of a bullet game.
