Aleksandr Domalchuk-Jonasson (chucksterf10)

International Master of Chess

Known in chess circles as chucksterf10, Aleksandr Domalchuk-Jonasson is a formidable International Master who has mastered the finer points of blitz and bullet chess with a blend of sharp tactics and a playful spirit.

Rating & Style Highlights

  • Peak blitz rating: 2742 (Feb 2025)
  • Peak bullet rating: 2759 (Dec 2023)
  • Peak rapid rating: 2424 (Nov 2023)

Aleksandr is a lightning-fast thinker with remarkable tactical awareness – sporting an impressive 87.67% comeback rate and a knack for clawing victory even after losing pieces. Endgames are their playground, appearing in over 82% of games and often extending into long, tense struggles averaging nearly 84 moves per win. They currently hold a slight edge when playing white, boasting a 52.58% win rate as White.

The Openings Enigma

Fair warning: Aleksandr’s favorite opening is classified as Top Secret – guess they like to keep opponents guessing! Outside of top secret sauce, they have some love for the English Opening Reversed Sicilian Kramnik-Shirov Counterattack, scoring 50% wins, and their native mastery of the Indian Game Knights Variation East Indian Defense with a flawless 100% win record in limited plays. Slav Defense fans, beware – this is not their favorite dance, with a 0% win rate from a couple of games.

Game Rhythm and Psychological Quirks

Aleksandr plays best in the early morning at 7:00 AM sharp (yes, chess before coffee!), with the highest win rates during daytime hours like 11 AM and 3 PM. Their tilt factor is a modest 8 out of 100, which means they keep cool even when things get tricky – but don’t get complacent because their longest losing streak hit 8 games.

Recent Adventures on the Board

Among the many battles fought, a recent sharp encounter against misa_savic showed Aleksandr’s resourcefulness – clinching victory on time after an intense positional fight in the English Opening Reversed Sicilian. Games involving famous opponents like thefrenchraclette and x4md40 have delivered both hard-fought losses and sparkling wins, each refining the skill and resolve of this IM.

Chess Personality

When Aleksandr steps to the board, expect a blend of daring and patience, a player who will not surrender easily (early resignation rate under 1%) and who gleefully drags opponents through complex endgame labyrinths. With nearly a thousand blitz wins under their belt, they clearly thrive in rapid-fire, high-stakes scenarios.

For fans of lightning chess and mind-boggling strategy, Aleksandr Domalchuk-Jonasson is a thrilling player to watch – whether they’re unraveling a “Top Secret” gambit or sneaking in a quiet King march to clinch the game at move 84.

Positive Highlights

Aleksandr, your recent rapid games show several encouraging signs of progress:

  • Consistent Rating Improvement: Your rating trend is steadily climbing, with a 41-point increase over the past month and a positive trend slope exceeding 40 points, indicating solid and sustainable growth.
  • Strong Opening Repertoire: You have a 100% win rate with the Nimzo-Larsen Attack: Classical Variation and the English Opening: Anglo-Indian Defense, alongside very strong results in the Barnes Defense and London System variations. This shows good preparation and understanding in these lines.
  • Effective Attack and Tactical Play: Your wins display active piece play and tactical awareness, such as capitalizing on opponent weaknesses and initiating dynamic moves like early knight maneuvers and pawn structure pressure.
  • Resilience and Conversion: A near 60% strength-adjusted win rate and your current undefeated stretch over the last 6 rapid games in December demonstrates your increasing ability to convert advantages and hold composure under time pressure.

Areas for Improvement

To continue your upward trajectory, focusing on the following areas could be beneficial:

  • Opening Consistency: While some openings yield excellent results, revisit lines such as the English Opening: Symmetrical Variation and the Nimzo-Larsen Attack (general), where you have faced losses. Deepening your understanding here will reduce vulnerability to surprise or discomfort positions.
  • Middle Game Strategy: In your recent loss versus HotGrainOfRice, challenges arose from structural difficulties and response to central pawn tension. Consider practicing strategic plans around pawn breaks and piece coordination in closed or semi-closed positions.
  • Time Management: While active use of time is good, ensure critical moves aren't rushed especially when transitioning from opening to middle game, to reduce tactical oversights. Your clock usage shows you sometimes have less than ideal time remaining in later moves.
  • Endgame Technique: Although your recent games showed good finishing, refining understanding of common endgame motifs especially in pawn endgames or minor piece endings will enhance your ability to convert small advantages consistently.

Practical Suggestions

To capitalize on your strengths and address development points, try the following:

  • Review and expand key opening lines with engine assistance or training videos focused on your less consistent openings.
  • Analyze losses to identify decision moments where alternative strategic choices could improve position — focus on pawn structure dynamics and piece activity.
  • In training, simulate rapid time controls to improve calculation speed under pressure, especially in tactically sharp positions.
  • Practice endgame puzzles regularly and study model endgames to build confidence in conversion techniques.

Summary

Aleksandr, your recent results and rating gains highlight strong improvement and growing mastery of key openings. Focus now on leveling up your middle and endgame technique and fine-tuning your opening consistency to break into even higher performance levels. Your dedication is paying off — keep up the hard work and thoughtful study!
