Maciej Czopor - International Master

Known on the chessboard and the internet as mac0504, Maciej Czopor is an International Master whose chess journey has been nothing short of a rollercoaster thriller—except without the cotton candy and loops.

Rising Through the Ranks

Maciej's path from a modest bullet rating of 1400 in early 2018 to a blistering peak of 2738 in Bullet and 2790 in Blitz by mid-2024 is an epic saga. If chess ratings were horsepower, Maciej would be a fire-breathing dragon revving up with every game. His rapid rise and aggressive style are evident in a remarkable longest winning streak of 16 games, proving that when he’s rolling, few can stop him.

Style & Strengths

Known for conciseness in the endgame (72% endgame frequency), Maciej embraces complexity with an average of roughly 69 moves per win, not afraid to delve deep into strategic melee. His comeback rate after setbacks is an awe-inspiring 78.7%—so if you think he's down and out, beware, the comeback kid has already plotted your downfall!

Despite a tilt factor of 9 (because who doesn’t occasionally want to flip the board?), his psychological resilience often shines in crunch time, especially in blitz and bullet, where fast thinking and nerves of steel are necessities, not options.

Notable Statistics & Trivia

  • Overall Blitz Win Rate: 53.6% (over 4,000 games)
  • Bullet Win Rate: 57% (consistently outsmarting opponents in lightning-fast games)
  • Favorite Playing Hours: Turns out early mornings and late nights are prime Maciej times (ironic for a chess player!)
  • Opponent Nemeses Include Michal Fiedorek and Matek18, against whom Maciej holds a solid winning record.

Recent Battles

In December 2024, Maciej demonstrated tactical wizardry with victories in classic openings like the Kings-Indian Attack and the Nimzowitsch-Larsen Attack, besting notable opponents on Chess.com with a combination of patience and opportunistic timing. His losses? Well, even the best have their off days — or as Maciej might say, “experimental games for learning purposes.”

Off the Board

While not officially a comedian, Maciej’s playful handle and spirited gameplay hint at a personality that enjoys both the battle and the banter. His aura suggests he might chuckle nervously during a losing streak and laugh hysterically when he’s on a winning one. But don’t let that fool you—behind the smiles is a fierce competitor honed by thousands of blitz duels.

Follow Maciej Czopor's games to witness a master balancing speed, strategy, and a good dose of chess mischief.

Your Competitive Strengths

  1. Tactical Awareness in Dynamic Positions
    Games such as the win against Arystanbek Urazayev show fearless piece activity and accurate mating nets (30.Rh5#). You spot forcing lines quickly and capitalise when the initiative is yours.
  2. Central Pawn Levers
    Timely thrusts with f4–f5 or d4–d5 consistently unbalance the position and create practical chances in short time-controls.
  3. Adaptability Against Higher-Rated Opponents
    Multiple upset wins versus 2700+ blitz players demonstrate healthy self-confidence and opening variety.

Main Improvement Themes

  1. Time Management in Bullet
    Four of your last six losses were on time in roughly equal or winning positions. Adopt a “moved-on-every-beat” rule: if your clock shows <25 s, play a safe half-move every heartbeat, relying on your tactical instincts.
  2. King Safety During Pawn Storms
    In the loss to PhysioTherapist (A07) the move 10.Be3 neglected Black’s …h5–h4 idea. When you push wing pawns (g4/h4 structures) scan for counter-punches like …h5 or …Ng4. Insert a prophylactic move or adopt a safer king route.
  3. Conversion Technique in Simplified Endgames
    The marathon versus SpeedofLight0 featured a two-pawn edge that dissolved into resignation. Practise technical endings (rook + pawn, opposite-colour bishops) 10 min daily on a drill site or with table-base quizzes.
  4. Handling the Nimzo-Larsen as Black
    You mirror 1.b3 with …a5/a4 but often cede the centre. Consider the modern antidote 1…d5 2.Bb2 Nc6 3.Nf3 Nf6 followed by …Bf5 or …Bg4, claiming space and faster development.

Opening Benchmarks

ColourCurrent ApproachSuggested Add-On
WhiteKIA & English move-order tricksAdd one main-line weapon (e.g. 1.e4 with Scotch), analyse 5 model games weekly
Black vs 1.e4Nimzowitsch-Scandinavian hybrid (…Nc6 & …d5)Develop a classical back-up (e.g. French or Najdorf) to avoid being move-ordered

Tactical Exercise from Your Play

Try to find the winning continuation before revealing the PGN (theme: Zwischenzug):

Action Plan for the Next 4 Weeks

  • Daily: 15 bullet games focusing on clock discipline; annotate 2 of them immediately.
  • 3× per week: Endgame drill set (20 positions) with a 30-second think limit.
  • Weekly: Deep-dive one recent loss; recreate the critical position on a board and ask “what would fear make me overlook here?”
  • Bi-weekly: Play one rapid game (15 + 10) using your secondary openings to broaden strategic understanding.

Keep in Mind

“Fast hands are great, but fast & correct hands win tournaments.” — Your future self after shaving 20% flag-outs.

Good luck, Maciej! Keep the energy, refine the structure, and the next peak rating will follow.
