Benjamin Bok — Grandmaster, Streamer, Blitz Specialist

Benjamin Bok is a Dutch chess Grandmaster and charismatic streamer known online as GMBenjaminBok. A fixture of modern online chess, he blends elite OTB pedigree with the speed and swagger of top-tier blitz. Preferred time control appears to be Blitz, and his fans tune in to watch him juggle calculation with banter, punish LPDO, and launch the occasional Harry pawn for good measure.

As a content creator and chessfluencer, Bok brings kindness and clarity to tough positions, all while keeping an eye out for a cheeky Swindle or a clean, technical conversion. It’s part classroom, part arena, and frequently ends in a little Flagging.

Style and Approach

GMBenjaminBok’s games often reach deep endgames, showcasing patience, conversion technique, and a love of the grind. When the position calls for it, he flips the switch into full-on Blitzkrieg mode, cashing in initiative and momentum for practical chances.

  • Strategic core: sound structures, piece activity, and king safety before the fireworks.
  • Practical instincts: he squeezes small edges into a Technical win, then backflips into tactics if the position demands it.
  • Entertainment factor: playful jabs at the Botez Gambit and instant radar for Cheap shots.

Repertoire Highlights

Bok is versatile, but a few lines have become calling cards in his blitz streams and match play. Expect principled development with a healthy dose of ambushes.

  • London System: Poisoned Pawn — a comfort zone in online Blitz with an imposing score. It’s “London enjoyer,” but with venom.
  • Sicilian Defense: Najdorf Variation — razor-sharp counterplay, blending theory with on-the-fly ideas. Think initiative, activity, and the occasional thematic Pawn storm.
  • Amar Gambit and surprise systems — coffeehouse vibes when it’s time to unsettle and out-hustle.

Under the hood he’s as prepared as they come, but never allergic to a fresh Novelty if it boosts practical chances.

Notable Online Battles

As a streamer, Bok regularly queues into the elite. He has logged marathon clashes with players like hikaru, danielnaroditsky, and grinder-in-chief jospem. The result is a highlight reel of clutch defenses, clean attacks, and “how-did-he-find-that?” endgames—plus the occasional chat-approved Swindle.

Streamer Presence

On stream, Bok blends elite calculation with humor, explaining plans, trade-offs, and when to go full “pre-move wizard.” Viewers learn how to balance structure with aggression, when to trust a Human move over the cold “0.00,” and how to avoid a tilt-inducing Mouse Slip.

Milestones and Fun Facts

  • Title: Grandmaster (FIDE)
  • Streamer: consistent, instructive, and occasionally a certified Swindler.
  • Peak Blitz power: 3143 (2025-07-01) — backed by volume, quality, and relentless consistency.

Why Fans Love GMBenjaminBok

In short: a Dutch GM who makes high-level blitz feel both learnable and exhilarating.

Hi Ben, here is some quick, data-driven feedback from your latest blitz session.

What’s already working well

  • Opening breadth. You comfortably switch between the Nimzo-Indian (E36), QGD Exchange (D35) and the Najdorf/Dragadorf (B94/B90). This keeps opponents guessing and often earns you an early lead on the clock.
  • Practical decision-making. Your most recent win against Attack_156 showed excellent “keep the pieces on” technique: 18…Nd4! and 19…Rc2! converted pressure straight into material.
  • Creating counter-play when worse. Even in the loss to Daniel Naroditsky you found 42…Nh3! and set real mating tricks – good fighting spirit.

Recurring issues worth fixing

  1. Time-management. Four of the last six losses featured time forfeits or <3-second scrambles from equal positions.
    Action: Add 10-minute “clock-only” drills (move instantly when ≥30 s; think only when <30 s). After two weeks, splice in to verify improvement.
  2. London-system frustration. Your 0-1 loss (D02, 1 d4 Nf6 2 Nf3 d5 3 Bf4…) follows a pattern:
    • …c5/…Qb6 grabs a pawn but leaves …c4 + weak dark squares.
    • Missing the thematic break …e5 when White’s queen is still on c1/c2.
    Action: Prepare a cleaner antidote: 1…d5 2.Nf3 Nf6 3.Bf4 c5 4.e3 Nc6 5.Nbd2 g6. Aim for a King’s-Indian structure where …Nh5 immediately challenges the bishop. Annotate 15 model games and tag each with Prophylaxis ideas.
  3. Kingside pawn storms in the Dragadorf. In the defeat by The_Berserk_Musketeer you allowed 17.g4-h5-h4 with zero counter-punch on the queenside.
    Action: Adopt Najdorf main-line 6…e5 or, if you keep 6…g6, memorise the forcing sequence 11…b4 12.Nd5 Nxd5 13.exd5 Na5 14.Qxb4 Bd7! holding the dark squares.
  4. Endgame conversion vs. passed pawns. The London loss ended with 36…Rc8?! allowing the b-pawn to reach b6-b7-b8. Similar story in the A07 game (h-pawn break).
    Action: Daily 15-minute session on rook-and-pawn vs. passed pawn endings. Use the “side file passer” theme in 3-5 positions until you can win/draw under 20 seconds per attempt.

Illustrative Micro-Tactic


The engines suggest a quiet 20…a5! (freezing the pawn chain) instead of 20…Ne4?!. Worth adding to your rehearsal file.

Training dashboard

  • Peak blitz rating: – aim to beat it after the next Arena Kings.
  • Opening focus for June: Anti-London + Najdorf g6.
  • Weekly review target: 5 wins, 3 losses fully annotated with at least one highlighted Zwischenzug.

Motivation corner

You’re scoring 70 % in games that reach move 35+. Once the clock issue is under control, your overall win-rate should climb sharply. Keep the energy high and let’s make the late-game your signature strength!


Good luck in the next Arena Kings! – Your digital second
