What You're Doing Well
Leonardo, your recent games show some strong areas of play that are worth highlighting:
- Successful Opening Choices: You have achieved good results in the Sicilian Defense Dragon Variation and the Closed Sicilian, winning all your games in those lines. This shows solid preparation and understanding in complex, tactical openings.
- Consistent Rating Improvement: Your rating has steadily increased over the past months, with a current upward trend and a notable gain of 41 points in the last 6 months. This reflects continuous improvement in your overall play.
- Good Endgame Skills: In your wins, you successfully converted advantages in the endgame, demonstrating good technique and patience in pressing your position.

Areas for Improvement
There are specific aspects where further focus could help enhance your results:
- Opening Variety and Stability: Some openings like the English Symmetrical Variation and East Indian Defense show no wins and more losses or draws. Consider deepening your preparation in these lines or exploring alternatives that suit your style better to improve your overall performance.
- Mistakes in Tactical Positions: In your losses, tactical oversights led to decisive disadvantage, such as early queen attacks and structural weaknesses. Working on tactical puzzles and pattern recognition can boost your ability to avoid these traps.
