Meet Gudmundur Kjartansson, a grandmaster whose chess skills have evolved like a well-adapted species in the wild ecosystem of the 64 squares. With a FIDE Grandmaster title under his belt, Gudmundur thrives in the high-paced environments of Blitz and Rapid chess, wielding his opening repertoire—top secret, naturally—like a masterful predator stalking its prey.
Over the years, Gudmundur’s rating has blossomed spectacularly, hitting a peak Blitz rating near 2674 and a Rapid zenith of 2676, showing impressive endurance and tactical prowess. His "endgame frequency" is a staggering 87%, proving that when it’s time to strip down to bare bones and close out the match, he pounces with precision and patience. His average moves per win clock in around 77, demonstrating a game plan built on calculated growth rather than rash gambits.
Gudmundur exhibits an evolutionary advantage in psychological resilience with a tilt factor as low as 5, and a comeback rate close to 92% — he bounces back like a hardy species recovering from ecological stress. Even after losing a piece, his 100% win rate says he’s got the cellular regeneration of a starfish when it comes to turning disadvantage into opportunity.
On the battlefield of Blitz, he’s racked up over 300 wins with a win rate over 53%, and across all time controls, his tactical awareness and consistency ensure he rarely succumbs to 'one-sided losses.' He’s the kind of player who refuses to be a sitting duck—chess instincts finely tuned, possibly influenced by a hidden neural network in his brain growing at a logarithmic rate.
Facing a variety of opponents, Gudmundur has built relationships akin to ecological niches: some adversaries he dominates with a flawless 100% win rate, while others provide more challenging encounters that keep his strategies constantly adapting and evolving. This dynamic is part of what keeps his game from becoming extinct or stagnant.

Gudmundur Kjartansson – Blitz Coaching Feedback
Quick Snapshot
- Current format: Blitz (3 + 1)
- Highest recorded blitz rating: 2681 (2023-09-07)
- Typical style: Dynamic, pawn-storms on the wings, enjoys open tactical fights.
What You’re Doing Well
- Opening Initiative
Consistently seizing space with g-pawn thrusts (e.g. 7.g5 in your Philidor win). You understand when a pawn storm will drive the opponent’s pieces back. - Piece Activity
Games show early Qg4/Qg5 ideas, rapid long-castle, and rook lifts (Rg1, Rh1, etc.). You rarely leave pieces undeveloped. - Tactical Awareness
Attractive combinations such as 22.Bxf7+ Kd8 23.Qc7# against Raul Adrian Habiaga demonstrate sharp calculation.
Key Areas to Improve
- Clock Management (5 of your last 6 losses were on time)
• Enter critical middlegame positions with >40 s whenever possible.
• Practise “move-now-think-on-opponent’s-time” drills; aim for ½ second pre-move decisions in familiar structures. - King Safety While Attacking
• Loss vs Yidong Chen shows queenside castling followed by a5/b5 pawn breaks left your king exposed.
• When you castle long, do a quick “pawn shield audit” before pushing flank pawns. - Conversion Technique in Simplified Positions
• Timeout vs Viktor Neustroev after reaching a pleasant position proves you spend too long finding “best” moves.
• Rehearse basic rook endgames and two-result positions; play the first safe winning line, not the prettiest.
Training Plan (2-Week Cycle)
| Focus | Tool / Drill | Goal |
|---|---|---|
| Time-Pressure Habits | 1-minute “Blitz Finish” sparring from move 25 | Average decision time < 2 s |
| King Safety | Annotate 10 own games where you castled long | Create a castle-long checklist |
| Endgame Conversion | 30 rook-v-rook puzzles (Lichess Drill IDs 1900-2200) | 90 % success rate in <30 s each |

Action-Item Checklist
- ⏱️ Start every blitz session with a 3-minute bullet warm-up to switch on fast calculation.
- 🛡️ Before aggressive pawn pushes, ask: “How many moves until my king has zero cover?”
- 🏁 Practise forcing sequences in won endgames; avoid “paralysis by analysis.”
- 📒 Keep a one-page “blitz heuristics” sheet (critical squares, safe pre-moves, endgame motifs).
Glossary
You may hear me reference Zugzwang, triangulation, and prophylaxis in future notes—feel free to ask for deeper dives.
Keep the momentum, Gudmundur!
