Karl Thorsteins - International Master Extraordinaire
Title: International Master (FIDE)
Karl Thorsteins, known in the chess community as hakki1, is a formidable chess talent who has steadily climbed the ranks to earn their well-deserved International Master title. With a blitz rating peaking at an impressive 2553 in 2023, Karl is a thunderbolt on the board, especially when the clock ticks down.
Rating and Performance
- Blitz Peak Rating: 2553 (2023)
- Rapid Peak Rating: 1573 (2022)
- Blitz Win Rate: About 52.4% over 1482 games with their secret weapon opening (quite literally labelled "Top Secret").
- Rapid Win Rate: About 54.5% in a handful of 11 rapid battles.
Style of Play
Karl's approach to chess is marked by resilience and patience. Famous for their no early resignations policy and a monstrous 82.25% endgame frequency, they prove that they prefer grinding down opponents in long, dramatic battles rather than quick tricks. True to their tactical prowess, Karl boasts an astounding 88.38% comeback rate — losing a piece? No problem! They win 100% of such games, showing nerves of steel matched by few.
Chess Personality
With a longest winning streak of 11 consecutive games and a respectable tilt factor of 6, Karl manages to keep their cool more often than not — but hey, who doesn't get a little fiery when the rook goes missing?
Fun fact: Karl's best days to strike are Sundays and Mondays, where their win rates rocket over 53%, and their favorite hours stretch from 9 AM to late at night, peaking at a perfect 100% win rate at the mysterious 6 AM hour (early bird or sleep-deprived genius?).
Rivalries and Opponents
Karl has faced hundreds of opponents, with “michael124667” being a frequent adversary, though with only a 40.74% win rate against them, proving even titans meet their challenges. Notable wins include perfect records against “sainasalonika” and “chessultramb,” who clearly didn't see Karl’s top-secret openings coming.
In Summary
Karl Thorsteins is the quintessential International Master: tough, relentless, and secretly scheming to pull off that improbable comeback every time the board looks bleak. Amid a sea of ratings and statistics, one thing is clear – when Karl sits down at the chessboard, every game is an epic in the making.
Hi Karl, here is your personalised feedback
Your current strengths
- Dynamic feel for double-fianchetto and Modern structures; you willingly fight for the initiative.
- Sharp tactical eye – e.g. the resourceful …Qxb3!! in your recent win over masteronfire4.
- Fast conversions when you seize a lead; most victories finish before move 30.
- Consistent practice – your activity curve () shows healthy volume.
Key areas to improve
- Opening hygiene
• Against 1.e4 you trust the early …Bf5 Caro-Kann Advance, but the 4.h4/4.g4 “Bayonet” lines leave your king exposed. Explore the quieter 4…e6 or 4…h6 branches.
• Versus 1.d4 your Modern/Pirc setup is fine, yet you sometimes postpone …c5/…e5 too long (loss on 04-May). Aim to challenge the centre by move 8, or add a Nimzo-Indian to diversify.
• Build a 10-move “menu” for each colour; revisit it quickly before each session. - Pawn-storm discretion
Premature …g5/…h5/…a5 thrusts (see defeat vs lordpyrrhicvictory) arrive while pieces lag. Before pushing a wing pawn ask:
Is my king safe? Are all minors developed? Do I control the centre? - Endgame conversion
Two losses (e.g. vs Spiderman-83) came from drawable rook-and-pawn endings. Spend 15 min/day on basic rook-endgame drills; “100 Endgames You Must Know” covers 90 % of what you need. - Time management
Even with a 2-second increment you drop below 2 s/move after move 25 ( shows the spikes). Adopt the “make a move only after you rebuild 5 s” rule. - Defensive calculation
In the 22…Nb3⁺? game you missed White’s exchange sac. Add 5 defensive puzzles to every tactics set and calculate three ply deeper than your own threat.
4-week micro-plan
| Week | Focus | Daily micro-task |
|---|---|---|
| 1 | Clean Caro-Kann lines | Review 10 master games & create flashcards |

| 3 | Endgame technique | 10 positions from “100 Endgames…” played vs engine |
| 4 | Clock discipline & tactics | 30 timed puzzles (3 min) + five 5|5 games |
Your milestones
• Personal best: 2553 (2023-05-29)
• Short-term target: 2550 by July with a +5 % late-game save rate.
Illustrative moment
Freeze the board before revealing the continuation; try to calculate for both sides:
Stay disciplined, keep the king safe, and your attacking flair will shine even brighter. Good luck, Karl!
