Grandmaster Ori Kobo (aka OK97)

Ori Kobo, proudly bearing the title of Grandmaster bestowed by FIDE, is a formidable force in the world of chess. Known to most by the enigmatic username OK97, Ori is a master tactician with a penchant for blitz battles and rapid-fire decisions that leave opponents scrambling.

Rise Through the Ranks

Ori's journey began with a modest blitz rating around 1600 in 2017, but it was clear this was just a warm-up. Over the years, Ori's rating soared to an astonishing peak of 2946 in blitz (April 2024) and an even more jaw-dropping 2979 in bullet (June 2024). Talk about speed chess domination!

Playing Style and Statistics

The secret of Ori's success? A blend of relentless tactical awareness, remarkable comeback skills (an 87% comeback rate!), and an average of 84 moves even in wins and losses — meaning Ori fights hard for every point. Always wary of psychological ups and downs, Ori’s famous tilt factor is a mere 9, proving resilience is as important as any opening theory.

White pieces tend to bring out the best with a 58% win rate, while black holds strong as well, winning more than half the matches. Ori also has a peculiar habit of shining brightest early in the morning—3 AM seems to be prime time for checkmating brilliance!

Openings? Classified!

With over 11,700 blitz games played under the cloak of "Top Secret" openings, Ori keeps rivals guessing. Highlights include a 100% win rate in rare but effective plays like the Caro-Kann Defense Exchange Variation and the Reti Opening Nimzowitsch Larsen Attack.

Recent Battles

Ori’s recent victories often ended by resignation—a gentle way of saying "I’m just too good for you." Among the impressive games is a complex 2025 win against Marcus_Harvey using the Reti Opening Nimzowitsch Larsen Attack, showcasing brilliant positional play and tactical sharpness. Losses are rare but fiercely fought, reminding everyone that even the best can stumble—but only briefly.

Record and Rivalries

Beyond numbers, Ori has faced thousands of opponents, developing rivalries with notable names like maitreia and alexrustemov. Win rates vary, but the fight is always intense. With thousands of wins to the credit and an uncanny ability to pressure opponents into submission or blunders, Ori’s games are as thrilling as a rollercoaster — with less screaming, more checkmates.

Fun Fact

When not dazzling on the digital board, Ori’s blitz games have an early resignation rate of just 0.4%, which means: they rarely leave opponents hanging too long before delivering the knockout punch. Efficiency is key — because who has time for drawn-out suffering?

Ori Kobo, the stereotypical speed chess ninja, reminds the world that while the game is centuries old, the warriors keep getting sharper, faster, and a touch cheekier.

Overview of your recent blitz play

Your recent blitz activity shows you can swing between sharp, tactical play and solid defense. You won a dynamic game by converting initiative into material and a decisive endgame, lost a tense middlegame where Black counterplay proved too strong, and drew a complex rook ending where accuracy mattered. The pattern suggests you handle sharp, attacking ideas well, but there are moments where quick, calm calculation and cleaner trade decisions could help you convert more often in blitz.

What you’re doing well

  • You stay active and create practical chances in sharp positions, especially when your opponent’s king is exposed. This helps you seize the initiative and pressure the defenses.
  • You convert strong middlegame activity into tangible edges, often transforming pressure into material gains or decisive endgames.
  • You fight to the end in tough positions, keeping your opponent on the back foot with energetic piece activity and timely pawn advances.
  • Endgame awareness shows in several games where you pursued passed pawns and used king activity to press for a win or hold a difficult endgame.
  • You use practical safety checks in a blitz setting, avoiding some trivial blunders and keeping the game within a fighting margin.

Areas to improve

  • Reduce unforced errors by adding a quick safety check after every candidate move: confirm what your opponent threatens, what trades simplify the position, and whether your king or important pieces become exposed after trades.
  • Improve time management by setting a mental 2-3 move plan before each move, especially in the middlegame, so you don’t end up in rushed decisions near the time control.
  • In openings, pick 1-2 ideas to play with both colors and study the typical middlegame plans and typical pawn structures. This helps you recognize key plans quickly in blitz.
  • When you feel pressure, prioritize simplifying to a clean endgame rather than seeking complicated tactical shots that may backfire under time pressure.
  • Strengthen endgame technique, particularly rook endings and pawn endgames, so you can convert more wins from favorable positions that you reach in blitz.

Openings and practical plan

Your mixed openings show you’re comfortable in flexible systems, but a focused plan can boost your consistency. Consider choosing 1 black and 1 white opening to deep dive this month, so you know the typical plans and endgames you’ll reach in blitz. For example:

  • For black, sharpen the Pirc/Modern-type setups you’ve been using, focusing on the key ideas behind the pawn breaks and piece activity in the middlegame.
  • For white, pick a reliable system such as a solid queen’s pawn setup or a flexible English/Borg. study the main middlegame themes and typical piece maneuvers.

Additionally, practice quick pattern recognition in common blitz structures (rook endings with exposed kings, or minor-piece endgames with pawns) so you can transition to confident endgames faster.

Training plan for the next two weeks

  • Daily puzzles: 5–10 minutes focusing on tactics that appear in your recent losses and near-misses.
  • Post-game review: after each blitz session, spend 5 minutes reviewing one win, one loss, and one draw to extract a concrete lesson from each.
  • Endgame practice: 10 minutes of rook endgame drills (rook vs rook with one or two pawns) to improve conversion and defense in blitz.
  • 2-mly two-minute drills: play short, two-minute games and deliberately practice the quick plan-and-trade approach—identify a plan within the first 4 moves and stick to it.
  • Time-check habit: use a simple 10-second pause before finalizing a move when in time trouble, to catch obvious blunders or threats you might have missed.

Notes on your rating trend and what it means for you

Your long-term trend shows steady improvement, with short-term fluctuations typical for blitz activity. The current one-month drop alongside a longer positive trajectory suggests you’re capable of bouncing back quickly, especially when you lock in consistent practice and a reliable endgame routine. Use the upcoming sessions to build a repeatable pre-move routine and a robust endgame plan, so you can translate your initiative into more clean conversions under time pressure.

Quick coaching ideas you can start today

  • Before every move in a sharp position, state your plan aloud in your head for 5–7 seconds: what is my aim this move, what does my opponent threaten, and what trades help or hurt me?
  • Pick 1 opening idea to master this week and rehearse the standard middlegame plans so you recognize them instantly in blitz.
  • During endgames, force yourself to count a few moves ahead in terms of who can threaten which pawns, and keep your king active—this often decides the result in blitz.
