Playing style
Arthur plays a pragmatic yet combative game. In Blitz he leans on practical openings that lead to sharp, tactical positions, while in Rapid he enjoys a wide, flexible repertoire that keeps opponents guessing. His approach emphasizes fast development, pressure on the center, and the readiness to seize dynamic chances when the moment arrives.
You show a strong tactical sense and are comfortable taking the initiative in dynamic positions. When you can steer the game into sharp middlegames, you often come out ahead.
Your openness to aggressive openings helps you seize early activity and create chances. This attitude can overwhelm less prepared opponents.
You can execute complex sequences when you spot them, which can swing momentum in your favor and lead to decisive wins.
Patterns from your openings and what they imply
London System: Poisoned Pawn Variation has not yet produced wins in your recent sample. This line tends to become very sharp and requires precise preparation. Consider either deeper study of typical middlegame ideas or choosing a different Black response to steer toward more manageable positions. London System: Poisoned Pawn Variation
You have produced strong results in several aggressive setups (French Defense, Amazon Attack, Ruy Lopez: Berlin Defense, Hungarian Opening, Alekhine Defense, English Opening, Petrov’s Defense, and QGA with Nc3) when you navigate the position confidently. This suggests you perform well when you control the tempo and coordinate pieces actively. Keep building a coherent plan for these lines.
Key areas to improve
Endgame technique: strengthen rook and minor-piece endgames so you can convert advantages or hold draws after exchanges.
Opening preparation for the London System: Poisoned Pawn Variation: decide whether you want to invest more study into this line or choose a safer alternative to avoid getting into overly sharp, unfamiliar positions.
Calculation discipline: in complex middlegames, develop a simple, repeatable process to verify forcing lines and avoid overextending on uncertain tactics.
Time management in rapid play: practice a steady development plan in the first 15 moves and reserve time for critical decisions later; avoid getting stuck deciding between multiple candidates for too long.
Suggested training plan
Endgame focus: dedicate 1–2 sessions per week to rook endings and king activity to improve conversion in simplified games.
Tactics routine: commit 15–20 minutes daily to tactical puzzles, emphasizing motifs like pins, forks, skewers, and back-rank weaknesses.
Opening reinforcement: pick 1–2 openings you use most often and study their typical middlegame plans and common pitfalls. Use short annotated model games to build a practical repertoire.
London System planning: either deepen your understanding of the Poisoned Pawn lines or establish a solid alternative against this setup to avoid uncomfortable positions.
Post-game reflection: after each rapid game, write down 3 mistakes and 3 lessons; review with a quick, light analysis or a coach when possible.
Next steps
Start applying this plan over the next 4 weeks, with a weekly review to track progress. You already have a solid foundation; targeted work on endgames, opening depth, and disciplined calculation will help you convert your tactical strengths into more consistent results.
