Sample game sequence:
Recent rapid games: quick take
Your most recent win shows you can press for a decisive result when you gain the initiative, finishing with a sharp, coordinated attack. Across your recent games, you’ve shown willingness to enter tactical complications and to strive for concrete openings and middlegame plans. Overall, you’re on a constructive path in rapid play and are building momentum in your chosen openings.
Strengths to lean on
- Active, aggressive approach when the position opens up; you seek forcing moves and dynamic piece activity.
- Comfort with sharp lines in your openings, especially when you can mobilize rooks and the queen to create pressure.
- Good ability to convert middlegame opportunities into clear advantages and wins.
Key areas to improve
- Endgame technique: sharpen your conversion of advantages into clean endings, with a focus on rook endings and pawn endings where king activity is critical.
- King safety during attacks: balance aggression with solid defensive checks. Avoid overextension that can invite counterplay or back-rank threats.
- Calculation discipline: when you enter tactical sequences, pause to verify critical lines and avoid rushing to sharp but risky continuations.
- Opening consolidation: pick a small, practical repertoire (2–3 main lines) and study typical middlegame plans and pawn structures so you can transition from opening to plan smoothly.
Practical drills for the coming week
- Endgame focus: practice two-rook endings and rook + minor piece endings, emphasizing king activity, opposition, and plan-following.
- Tactical pattern training: 15–20 puzzles per session targeting motifs you’ve encountered (overloads, back-rank themes, discoveries, and forced sequences).
- Opening study: solidify your main openings with a one-page outline per line, including typical middlegame plans and key squares to control.
- Post-game self-review: after each rapid game, write down one idea you executed well and one alternative safe plan you could have chosen instead of a risky line.
