Your Strengths
You play with real aggression and you rarely let an attack fizzle out. In your win against mahan3243 you chose a sharp Caro-Kann Defense line, pushed the kingside pawns, and kept creating threats even when your clock was nearly empty. That attacking spirit and willingness to fight in complicated positions is a big weapon.
You also showed good resilience in your draw against DrMikicic. After a complex Sicilian Defense battle, you defended an awkward bishop endgame and steered the game to a safe draw under heavy time pressure.
Time Management Needs Work
Your biggest problem in these games is the clock. In the loss to GiantOCR you actually reached a playable endgame but ran out of time, and against TrickyNuela you were checkmated while your clock was in single digits. Even in the win against mahan3243 you dropped below ten seconds several times.
This is a 3 minute blitz game with a 2 second increment. You can always gain time back by making a reasonable move. Try to avoid long thinking bursts early in the game, and save your deep calculations for moments where a piece is hanging or the king is in danger. When you are low on time, make your moves quickly and let the increment rebuild your clock.
Protect the King First
The Nimzo-Indian Defense game against TrickyNuela shows what can happen when king safety is ignored. After the capture on h6 and the bishop landing on h6, the squares around your king became weak, and the queen came to g6 before the final blow. Whenever the opponent grabs the initiative on the kingside, your first priority should be stabilizing the king, even if it means giving up some material or a tempo.
Stay Tactically Sharp Under Pressure
In the Scandinavian Defense game against Killerskiller2, you built a decent position as White, but a single move allowed the knight to capture your rook on f4, losing the exchange and the game. The move probably looked active, but it left a major piece undefended. Before you move a piece, scan for simple captures and checks your opponent can make. This is exactly the kind of tactical check that saves you from losing a game you are otherwise pressing in.
