Aleksandar (aka Aco30) - The Chess Virtuoso

Aleksandar, known in the chess world by his handle Aco30, is a formidable player who has been dancing with kings and queens since at least 2014. Aco30’s journey through the 64 squares is a tale of passion, perseverance, and a sprinkle of cunning cunningness.

Rating Rollercoaster & Style

Over the years, Aco30’s bullet rating has soared, dipped, and rocketed, reaching an impressive peak of 1801 in 2023, then steadily maintaining above 1700 in recent years. In blitz, he’s no less a warrior, reaching a max rating close to 1900, where speed and accuracy collide in dazzling fashion.

With a White win rate slightly edging out Black, Aleksandar likes to keep his options balanced but strikes hardest in blitz and bullet formats. Fun fact: his games feature an average of just over 62 moves, proving that Aco30 loves the long, thrilling battles.

Opening Repertoire

Aco30 is a master of several openings – the Scotch Game is a personal favorite in Bullet with over 600 games and a respectable 53%+ win rate. In Blitz, he absolutely shines with the King’s Fianchetto Opening and Owens Defense, boasting more than 65% wins – a true king of fianchetto flair!

But beware! His use of the Scandinavian Defense Mieses Kotrc Variation shows he’s not afraid to ruffle some feathers and catch opponents off guard.

Tactical Wizardry & Psychological Edge

Famed for a stunning 79.65% comeback rate and an eerie 100% win rate after losing a piece, Aleksandar channels the true spirit of a sacrificial strategist. His tilt factor is a modest 15, meaning even when things get rough, he keeps his head in the game—and his opponents sweating.

Trivia & Recent Adventures

  • Longest winning streak: A legendary 26 games in a row.
  • Current winning streak: Riding high with 3 straight wins.
  • Psychological quirks: Watch your time management; the last time Aleksandar won by checkmate was against Blacksray, showcasing a sharp finish under pressure.

Recent Games Highlight

In his most cinematic recent victory, Aleksandar broke minds and kings on May 21, 2025, with the Queen’s Pawn Opening, culminating in a stunning checkmate against a 1741-rated opponent here. His tactical sharpness left adversaries spellbound.

Play Style and Personality

Aleksandar has a reputation for patient, long games—he makes his wins count and keeps his losses tight, averaging almost equal moves in wins and losses (~62). When it’s time to fight, his endgame skills kick in (66.75% frequency), making him a tough nut to crack when the board empties.

Sometimes he’s a poker-faced magician, resigning early only ~1.2% of games, but don’t let that fool you – if a comeback is possible, his 100% success rate after losing a piece tells you he’s the phoenix of the pawns.

In a nutshell…

Aleksandar aka Aco30 is not just a chess player; he’s an arena tactician, a comeback king, and a master of fianchetto. Opponents beware, as his games are a complex dance of strategy, endurance, and a pinch of daring.

So next time you see Aco30 on the board, prepare for the unexpected—and remember: the chessboard is his playground, and checkmate is his signature move.

What you’re doing well

Your recent rapid results show a strong, hands-on style that puts pressure on your opponents early. You are comfortable choosing aggressive openings and getting your pieces out quickly to create activity and chances. Your performance in several sharp openings indicates you can handle dynamic positions and look for fast, practical solutions. A note on your trajectory: your rating trend slope has been consistently steady, suggesting solid, continuous improvement over time.

  • You perform particularly well in aggressive lines like the Amazon Attack and Amar Gambit, where you seize the initiative and push for quick activity.
  • You also show good results in other tactical setups, indicating solid tactical vision and the ability to spot dynamic chances when the position opens up.
  • When you gain activity, you coordinate pieces effectively to create threats and keep the opponent under pressure, which often leads to decisive tactics.

Areas to improve

  • Time management in rapid play: some games show long, complex sequences. Practice making confident, accurate decisions earlier in the game to avoid late-time pressure.
  • Endgame conversion: work on preserving and converting advantages in simplified endings. When ahead, consider simplifying only after strengthening your winning chances, and aim for clear plans rather than tactical improvisation.
  • Broaden your opening safety net: while aggressive lines serve you well, a few solid, less risky replies against less common defenses (for example against Barnes Opening and certain Queen’s Pawn setups) can help you avoid overextension and maintain a stable position.
  • Post-move discipline: after a tactic or a trade, quickly assess whether you still hold the initiative or if a safer, more positional route would be better. This reduces the risk of mis-evaluations in rapid time controls.

Opening trends to guide your study

Your results show strength in aggressive lines such as Amazon Attack and Amar Gambit, while a line like Barnes Opening: Walkerling has been less successful. To balance your repertoire, consider focusing study on a mix of lines that keep you active and a couple of solid replies to common defenses. For example, you can deepen the following areas:

  • Strengthen plans and typical middlegame ideas in Amazon Attack and Amar Gambit to convert initiative into clear advantages. Amazon Attack Amar Gambit
  • Develop a reliable, solid response against offbeat or less standard openings (e.g., Barnes Opening: Walkerling) so you’re comfortable returning to a sound structure when needed. Barnes Opening: Walkerling
  • Review common patterns arising in Philidor Defense Exchange Variation and Queen's Pawn Opening structures to improve transition from opening to middle game. Philidor Defense-Exchange Variation

Practice plan to implement improvements

To build on your current results, try a focused two-week plan that balances aggression with solid fundamentals:

  • Week 1: two openings per week—one aggressive (Amazon Attack or Amar Gambit) and one solid (Caro-Kann Defense or Czech Defense). Practice key lines and plan ideas until they feel natural.
  • Week 2: continue with the same approach, adding a short endgame drill (rook endings and basic king-pawn endings) to improve conversion when ahead.
  • Daily tactical warm-up (10–15 minutes) focused on motifs common in your openings (phones, forks, pins, discovered attacks) to sharpen calculation speed.
  • Post-game review: after each rapid game, jot down 2–3 takeaways (what worked, what didn’t, what you would do differently next time).

Sample practice material

Use the following placeholder to replay a quick opening-to-midgame transition in an aggressive line. Paste into your trainer or viewer as a practice exercise and work through the transitions at a comfortable tempo.
