David Kjartansson: The International Master with a Persistent Flair
David Kjartansson, known online as Yuwono, is no ordinary chess player. Holding the esteemed title of International Master from FIDE, David's chess journey is nothing short of inspiring, and occasionally sprinkled with the unpredictability that only true warriors of the 64 squares can experience.
Rating and Performance Highlights
From humble beginnings, with blitz ratings just shy of 1500 in 2013, David steadily climbed the ranks, eventually peaking at a blistering 2719 in blitz (August 2022) and an impressive 2771 in bullet (June 2023). Rapid play isn't left out of the glory either, with a peak rating soaring to 2631 late in 2022.
Playing Style & Personality
His games often stretch into the deep complexities of endgames, boasting an endgame frequency over 80%, proving he relishes the challenge when others might throw in the towel. David’s average game length for wins? A marathon-like 78 moves, showing remarkable patience.
Not one to surrender easily, this player exhibits a remarkable comeback rate of 84.5% and tends to keep calm even after losing a piece—winning 43% of those tense scenarios. Truly a fighter who believes every piece matters until the bitter end.
The Psychological Edge
With a tilt factor of just 14, David manages to keep his cool better than most when the pressure mounts. His preferred hour to test his mettle on the chessboard? Surprisingly, the wee hours at 5:00 AM—obviously when the real magic happens!
Recent Battles from the Battlefield
In his latest triumph, David showcased a strategic masterpiece in the Queen's Gambit Declined, patiently forcing resignation from his opponent with precise rook maneuvers and a knight strike.
On the flip side, even masters stumble. His recent losses include gripping encounters like the English Opening Two Knights Variation and Philidor Defense battles, demonstrating that even International Masters respect the unpredictability of chess and the cruelty of time scrambles.

Hi David, here’s some constructive feedback based on your recent games.
What you are doing well
- Energetic attacking play. With White you often seize the initiative early (e.g. the h-pawn storm in your blitz win) and keep your opponent on the back foot. Your tactical eye is sharp – you spot mating nets quickly when the king is drafty.
- Piece activity over material. In several victories you returned material to keep pieces active and the enemy king uncomfortable. That willingness to sacrifice for activity is a hallmark of strong practical play.
- Mixing time controls. You play both Daily and Live games. The extra calculation practice from correspondence is clearly helping your OTB/blitz tactical vision.
Key areas to improve
-
Time management – your #1 leak
Six of your last seven losses were on time in positions that were still very playable (or even better for you).
- Enter every game with a realistic plan for how much time you want left by move 20.
- When it is your opponent’s move, force yourself to rest the mouse and look at the board – do not check messages or other tabs.
- If Daily games are timing out, enable move reminders or reduce the number of concurrent boards.
-
Early‐middlegame plans as Black
In several lost Daily games you played …Bb4–Bf8 vs the English or the Philidor and ended up behind in development. Ask “What is my long-term pawn break?” before choosing piece squares. A sample improvement line:
Study model games in the Reversed Sicilian and the Lion to see how strong players coordinate their pieces. -
Converting technical positions
Even when clearly better (e.g. your Philidor game after 25…Nf4) you sometimes drift. Adopt a “triple-check” habit before every move:
- What is my opponent threatening?
- How do I improve my worst piece?
- Can I simplify to a winning endgame?
