Meet Alexander Katz, the International Master whose chessboard wizardry has dazzled fans on and off the digital battlefield. More than just a titleholder, Alexander is also a dedicated streamer, bringing the thrill of the game to audiences worldwide while juggling kings, queens, and the occasional streaming technical glitch.
Chess Journey & Rating Highlights
Starting modestly at a Daily rating of 1357 back in 2012, Alexander’s journey has been nothing short of exhilarating. Climbing steadily through the ranks, they peaked at an impressive 2212 in classical chess by mid-2016. However, the real fireworks come in Blitz and Bullet formats, with peak ratings soaring to 2851 in Blitz (early 2025) and a lightning-fast 2953 in Bullet (early 2023). For those who count every second, Alexander is a force to be reckoned with.
Style & Strengths
Alexander’s playing style is a curious concoction of resilience and tactical awareness. With an astounding 87.6% comeback rate, they tend to laugh in the face of adversity, often turning positions around after losing a piece with a steady win rate exceeding 52%. For fans who enjoy a nail-biting finish, their games average over 78 moves per win, proving patience can indeed be a virtue on the 64 squares.
Stream viewers know that resignations are rare; the Early Resignation Rate is a humble 1.8%, meaning Alexander fights on until even the last pawn is hanging by a thread. A true gladiator of the game!
Opening Repertoire
While the chess library is vast, Alexander loves to cozy up with the Pirc Defense and the Giuoco Piano, boasting win rates between 57% to 80% depending on the line and format. Modern and Sicilian defenses also pepper their playbook, hinting at an adaptable player who enjoys mixing classical chess theory with spicy tactical battles.

With over 4,900 wins combined across Daily, Blitz, Bullet, and Rapid time controls, Alexander maintains a hefty leaderboard presence. Their fiercest opponents include familiar faces like “eilyisum” and the formidable “danielnaroditsky,” against whom the battles have been epic and intense, albeit with some tilt-worthy moments (a tilt factor of 41 – shows Alexander’s human side!).

Performance snapshot for Alexander Katz
This feedback focuses on practical improvements you can apply to your blitz play. It uses your recent openings results and rating trends to highlight where you can tighten your game and build a more stable, repeatable approach under time pressure.
What you're doing well
- You demonstrate a solid understanding across a diverse set of openings, including modern and classic defenses. This breadth helps you adapt to opponents’ choices in blitz and keep your opponent guessing.
- Several openings you use show strong practical results, indicating you handle typical middlegame plans well and can convert advantages in many standard structures.
- Your ability to navigate sharp, tactical lines in blitz shows good calculation and pattern recognition under time pressure, especially in well-trodden lines where you know typical motifs.
- Consistent handling of dynamic positions with active piece play suggests you’re comfortable creating pressure and posing practical problems for your opponents.
Opportunities to improve
- Stabilize your blitz results under time pressure. The recent downward rating trend suggests you’re occasionally overextending in the heat of battle. Develop a clear, repeatable thought process to reduce risky decisions late in games.
- Time management during the opening and early middlegame. Build a plan for the first ten moves of your chosen openings and stick to a reasonable thinking budget before transitions to the middlegame.
- Blunder reduction in critical moments. Create a simple pre-move check: “What is my opponent threatening now? Am I leaving a minor piece or a tactical motif hanging?”
- Endgame conversion. Blitz games often reach simplified endgames where technique matters. Practice short endgames (king and pawn endings, rook endings) to improve conversion rates in tight time scenarios.
- Pattern-based study of top performing openings. While breadth is good, deepen your understanding of a smaller set of lines that fit your style so you can recall plans quickly when under pressure.
Opening performance highlights
- Najdorf Variation of the Sicilian and Scandinavian Defense show particularly strong performance, indicating you are comfortable in dynamic, imbalance-rich positions. Sicilian Defense: Najdorf Variation
- Caro-Kann Defense and Czech Defense also surface as reliable options in your blitz toolkit, suggesting solid, resilient structures you can rely on under pressure. Caro-Kann Defense Czech Defense
- Italian Game: Two Knights Defense and related lines demonstrate good practical play in early middlegame fights. Italian Game: Two Knights Defense
- Other openings like the Scandinavian Defense and Queen’s Gambit Declined family show you can switch to solid, plan-focused play when needed. Scandinavian Defense
Practical next steps
- Create a 2-week blitz plan: pick 2–3 openings you want to deepen, and build a simple move-by-move outline of typical middlegame plans in those lines. Then practice sticking to the plan within a fixed thinking time.
- Implement a daily 15–20 minute tactics routine focusing on common blitz motifs (forks, pins, discovered attacks) to sharpen quick recognition under time pressure.
- Run post-game reviews: for your last 5–10 blitz games, identify positions where you hesitated or blundered. Note what you missed and create a short checklist to avoid repeating those mistakes.
- Endgame drills: practice rook endings and simple king-pawn endings to improve conversion in time pressure scenarios.
- Time-management drills: in every game, set a small budget of time for the first 12 moves, then reassess. If you’re falling behind on the clock, switch to a safer, simpler plan to secure a usable position.
Starter study plan (optional)
If you’d like, I can tailor a one-week study plan with daily targets and quick practice tasks. It can include a short opening guide, tactical drills, and endgame exercises that align with your current openings and rating trend goals.
