Slaven Pastar - International Master Extraordinaire

Meet Slaven Pastar, proudly holding the prestigious title of International Master bestowed by FIDE – a badge of honor earned not by luck, but by sheer dedication, cunning strategies, and a hefty dose of pawns sacrificed in the name of glory.

Rating and Style

Slaven's chess ratings tell a tale of a fierce competitor across all time controls. With a peak blitz rating soaring to an impressive 2777 in May 2025 and a bullet peak of 2750 reached in October 2023, Slaven has shown remarkable ability to think quickly and decisively. Their rapid play peak of 2641 and steady daily ratings round out a versatile and formidable player.

Known for a profound fondness for the Unknown Opening in rapid chess (boasting an 81.11% win rate!), and a top-secret strategy that’s equally mysterious and effective (an 83.33% win rate), Slaven truly keeps opponents guessing. Whether executing a sneaky Queens Indian Defense or the tricky Panov Attack, this player’s opening repertoire is a chess buffet of surprises.

Playing Personality & Stats

With a staggering 3158 wins in blitz games, against 2958 losses and 497 draws, Slaven dances on the edge of victory and defeat, thriving in high-tempo confrontations. Their bullet battles showcase similar tenacity with nearly 1500 wins. Indeed, these numbers prove that they don’t shy away from chaotic scrambles or intense time-pressured puzzles.

Tactical awareness? Check – a comeback rate of 78.23% means Slaven is the kind of player who turns a disaster into a masterstroke. With a tilt factor of only 12, this player maintains composure even when the coffee runs out and the clock ticks mercilessly.

Favorite Time to Play & Quirks

Legend has it Slaven’s brain operates at its sharpest around 1 AM, when most mortals have surrendered to dreams of checkmates past. Whether it's the witching hour or any other, their winning streaks have been as long as 19 games – a night owl indeed!

Recent Battles

In their most recent games, Slaven has demonstrated precise positional insight and tactical brilliance. For example, a June 2025 blitz game against TenienteDan15 ended with Slaven flawlessly handling the Tarrasch Defense, Two Knights Rubinstein Prague Main Line– wrapping up the duel by resignation in just 22 moves. Clearly, Slaven doesn’t waste time in administering checkmate or making opponents admit defeat!

Opponent and Opening Playstyle

Slaven has squared off most frequently against players like cugimura (137 games) and ronartest77 (121 games), proving sturdy nerves and consistent performance. Their preferred openings include the classic English and Queen’s Indian varieties often peppered with some unpredictability that keeps adversaries on their toes.

Fun Fact

Despite the intensity of competitive chess, Slaven’s games average around 77 moves when winning – long, thoughtful battles where each piece feels its weight in the strategic dance. On the flip side, losses linger around 82 moves, showing that this player fights bravely to the end, never conceding without a fight.

"Slaven Pastar - proving that behind every great chess player is a legend armed with pawns, knights, and a touch of mystery."

What You're Doing Well

Slaven, your recent games demonstrate several strong attributes that contribute to your continued success:

  • Opening Preparation: You show confidence and good results with less common openings such as the English Opening: Agincourt Defense and solid systems like the Nimzo-Larsen Attack. Your win rate in these openings is above 50%, indicating good familiarity and comfort.
  • Endgame Technique: Your games often reach complex endgames where you demonstrate patience and precision, converting material and positional advantages into wins.
  • Consistent Rating Improvement: Your rating trend slopes suggest steady improvement over the last 6 months, with a notable 118 point gain and a strong slope in the shorter term. This reflects your ability to learn and adapt.
  • Time Management: In bullet format, you maintain solid time usage, keeping calm under pressure which is crucial in fast games.

Areas for Improvement

To continue your growth and improve your bullet games, consider focusing on these aspects:

  • Handling Tactical Pressure: Some recent losses result from tactical oversights or miscalculations under time pressure. Improving your pattern recognition and quick calculation accuracy will help reduce blunders.
  • Defense in Difficult Positions: In a few losses, you found yourself in tough defending scenarios where passivity allowed your opponent to take the initiative. Work on holding difficult positions and counterplay techniques.
  • Opening Diversification: While your current opening repertoire is effective, adding one or two more aggressive or surprise weapons could increase your chances against well-prepared opponents.
  • Drawing Conversion: Your draw count is modest compared to wins and losses. Improving your ability to hold and convert draws could stabilize your results, especially in tight games.

Next Steps for Training

  • Practice Tactical Drills: Incorporate daily short tactical puzzles focusing on common bullet tactics and checkmating patterns to sharpen quick tactical vision.
  • Analyze Your Losses: Review games where you were checkmated or lost on time to identify recurring mistakes or time management issues.
  • Endgame Study: Deepen your knowledge of key endgame positions so you can confidently convert advantageous endgames even in fast time controls.
  • Opening Review: Refresh your current openings and explore alternative lines to add variety and surprise value.
  • Play Slow Time Controls Occasionally: Mix in rapid or classical games to build longer-term strategic understanding which will benefit your bullet decision-making.

Summary

Overall, your bullet chess performance shows impressive strength and steady improvement. Your solid opening play, good endgame technique, and rating growth are commendable. By focusing on tactical speed, better defense under pressure, and diversifying your openings, you can take your bullet game to the next level. Keep training consistently and leveraging your strong points!
