Eyal Grinberg – International Master, Chess Dynamo

Meet Eyal Grinberg, a chess warrior who holds the coveted title of International Master granted by FIDE. Known in the chess world as rubhani, Eyal combines the precision of a surgeon with the tactical flair of a grandmaster in the making.

Starting from a modest 1370 Blitz rating in 2016, Eyal soared to an impressive peak of 2653 in 2018. That's a leap that would make even the most seasoned chess engines blink twice! Despite a few rating dips (because who doesn't have an off day?), this player’s average Blitz rating consistently hovered around the 2400 mark—enough to make opponents sweat bullets.

Eyal’s prowess isn’t limited to Blitz alone; they’ve dazzled in Bullet and Rapid too. With a Bullet max rating smashing well past 2800 in 2022, they're certainly not just fast on the clock but also sharp on the board. Their Rapid play saw a peak near 2570, proving adaptability across time controls.

Fun fact: Eyal can boast an 86% after almost losing – talk about fighting spirit! And if they lose a piece, watch out – they win nearly 95% of those games anyway. Clearly, Eyal doesn't just play chess, they wrestle it to the ground.

Eyal’s longest winning streak is 16 games, and currently, they're on a sizzling 3-game roll. Opponents beware: this master plays the game like it’s a thriller novel—full of twists and dramatic finishes that make every match a nail-biter.

As for style? Don’t expect quick quits – Eyal resigns early in only about 3% of games and loves the grind with an enviable endgame frequency above 75%. They average around 71 moves per win, so be ready to settle in for a marathon battle rather than a quick puzzle.

Off the clock, Eyal’s most frequent rivals include aliencowboy and johnathan113. Against some foes, Eyal’s near-perfect win rates (looking at you, toligor and friends with a 100% score!) suggest that these matchups are less battles and more performances of chess mastery.

When asked how Eyal spends their chess hours? Between 6 AM and 11 AM are their golden hours with win rates hitting the 50-55% mark, but a nocturnal guru they are not – the midnight hour is their least friendly zone.

Whether in Bullet, Blitz, or Rapid, Eyal Grinberg plays with a smile, a smirk, and a surprising amount of grit. If you're lucky, you might catch them online under their username, but if you’re unlucky? Well, prepare to be outplayed, outwitted, and outclassed.

Hi Eyal, great to see your recent games!

Snapshot

  • Current time-control focus: 3-minute blitz.
  • Your best blitz rating so far: 2653 (2018-12-23).

    to notice when your performance peaks.

Your strengths

  • Sharp tactical eye: In your Vienna Defence win versus Toligor you converted after 7…Rxh4! and 11…Nxc2!, seizing every tempo-gaining capture.
  • Flexible piece play: You switch smoothly between King’s Indian, Pirc-type pawn structures and English/Réti setups, keeping opponents guessing.
  • Practical mindset in complications: You tend to choose forcing continuations that put the clock pressure on the opponent—very useful in fast time controls.

Biggest improvement themes

  1. King safety after pawn thrusts.
    In several losses (e.g. vs arceusisthebest and pingpong2k) the sequence …b5-b4 or h-pawn storms created lasting dark-square holes around your king. Develop before you launch flank pawns and keep a minor piece near the castle.
  2. Conversion in favourable positions.
    Against fermatslastblunder you were a pawn up but drifted and resigned once the rook invaded. Add 10 minutes of end-game drill to each study session (rook vs pawn endings, opposite-coloured bishops). It will pay dividends.
  3. Clock management.
    Two defeats were on the clock or with <5 seconds while still equal on the board. Try the “10-second rule”: if you haven’t moved for 10 seconds in blitz, play the most forcing move available—even a small inaccuracy beats a timeout.
  4. Forcing sequences & calculation depth.
    Versus Jpablit you overlooked 28…Be4+!—a classic zwischenzug. Daily puzzle rush or one game of 5+5 where you verbally calculate lines will sharpen this skill.

Opening guide (next 2 weeks)

  • With White: Your Réti/English positions are solid, but sometimes the early b-pawn push costs time. Mix in 1.d4 Nf6 2.c4 to learn classical queen’s-pawn structures and reduce early pawn commitments.
  • With Black: Instead of the risky 1…a6/…b5 systems, test a reliable setup: 1.e4 e5 → 2.Nf3 Nc6 3.Bc4 Bc5 (you showed comfort here)
    1.d4 → …d5 and meet c4 with …e6 heading for an improved Queen’s Gambit Declined you can memorise in an evening.
  • Add one new mini-line each study day; annotate your blitz games afterwards to see if you followed the plan.

Illustrative moment

A single tactic decided your loss to Jpablit. Play through moves 22-31—can you spot Black’s winning idea sooner?


Action plan

  • Daily: 20 tactical puzzles + 10 min end-game drill.
  • Every other day: Review one of your own blitz games without an engine for 15 min, then with an engine for 5 min to confirm.
  • Weekly: Play two 15+10 games focusing on opening discipline; annotate them fully.
  • Track progress using the charts above and aim for a 5 % increase in win-rate during your best performing hour.

Keep the energy and creativity, Eyal, and blend it with a little more structure—your next rating jump is around the corner. Enjoy the journey!
