Sơn Đặng (aka NTBT_DHS) - International Master Extraordinaire
Sơn Đặng is an International Master who dances with pieces on the chessboard like an artist with a paintbrush — only the canvas is 64 squares, and the stakes are usually “checkmate or bust.” Known in the chess community as NTBT_DHS, Sơn has a knack for blitz and bullet chess, accumulating thousands of games over years with a win rate that would make a grandmaster nod in approval.
With a career spanning several years, Sơn’s blitz rating once peeked at a sizzling 2853 in early 2019, while his bullet prowess topped out at an astonishing 2906 in 2021 — numbers so high they’d make even the mighty Hikaru pause for a second. Rapid also isn’t to be forgotten, with a peak of 2274, proving that whether it’s lightning-fast bullet or the slightly more “thinky” rapid, Sơn brings the heat.
Playing Style & Stats
- Extremely resilient, boasting a comeback rate of nearly 86% after losing pieces.
- Prefers the complexity of the middle and endgame, pushing average moves per win to nearly 78.
- Favors playing the secret openings and unorthodox lines — opponents never quite know what to expect.
- Psychological insights: Known for a low tilt factor (only 17%), showing nerves of steel during heated matches.
Career Highlights & Anecdotes
Over thousands of games, Sơn Đặng has achieved breathtaking winning streaks (up to 22 wins in a row) that mystify viewers and opponents alike. Not one to resign easily, Sơn’s eagerness to fight back is legendary, with only about 2.2% early resignation rate — which means they play until the very last pawn is trembling.
Just recently in 2025, Sơn executed a clean victory against phanhoangtuananh with a precise checkmate in a well-fought Indian Game, Knights Variation — a real treat for students of finesse and timing. But even champions stumble, as a loss occurred shortly before against vasileiosfamtsakaloglou, reminding us all that chess is both art and battle.
Fun Fact
Despite the intense focus required, Sơn seems to play best around 1 PM, the “magic hour” with a peak win rate — the perfect time for coffee and crushing your opponent!
Whether blitzing through games or calculating deep endgame strategies, Sơn Đặng continues to be a formidable figure in the chess world — a player with both the tactical bite of a seasoned predator and the psychological stamina of a marathoner. Keep your kings guarded, because when NTBT_DHS is on the board, surprises are always just a move away.

Positives in Your Recent Bullet Games
Great job on several important aspects during your recent games:
- Aggressive and Tactical Play: In your wins, you effectively launched attacks targeting your opponent’s king, often resulting in decisive advantages or checkmate threats.
- Opening Preparation: You demonstrated strong familiarity with openings like the Trompowsky Attack and Queen's Gambit Accepted, helping you to rapidly develop pressure early in your games.
- Time Management: Despite the bullet time controls, you managed to play solid moves quickly, maintaining time to calculate critical tactics and endgame maneuvers.
- Endgame Technique: In your victories, you skillfully converted advantages into wins, showing good understanding of king and pawn endgames or material imbalances.
Areas for Improvement
While your play is strong, focusing on these areas can help improve consistency and results further:
- Decision Making Under Pressure: In losses, there were some moments of positional concessions or tactical oversights. Try to slow down even for a split second on critical moves to avoid unnecessary mistakes.
- Handling Pawn Structure Challenges: Several games showed you facing pressure from advanced pawns or isolated pawns. Reviewing pawn structure strategies and typical plans in your chosen openings can bolster your defensive skills.
- Opening Diversity: You have good strength in openings like the Modern Defense and Benoni Gambit, but diversifying your repertoire could reduce predictability and increase your chances against varied opponents.
- Endgame Precision: While your endgames are generally good, tightening calculation and avoiding small inaccuracies can help convert more games rather than letting win chances slip.
Long Term Development Insights
Your rating history and performance statistics reveal some key patterns:
- Your current strength adjusted win rate is slightly above 50%, indicating solid play against similarly rated opponents, but also room to increase that margin.
- Recent monthly ratings show a slight decline but the positive trend slope suggests an upward trajectory in skill over time — keep training and analyzing mistakes.
- Your best win rates are in openings like the Amazon Attack: Siberian Attack, with win rates above 52%. Consider deepening your knowledge in these lines to maximize your chances.
- Be cautious in defenses like the Modern and Australian Defense where you have slightly below 50% win rate — review typical traps and plans in these openings.
Continued focused study on positional understanding, tactical alertness, and sharpening your endgame technique will help you regain and surpass your peak ratings.
Next Steps for Improvement
- Study typical pawn structures and plans in your key openings to avoid getting into unfavorable middlegame positions.
- Use slow rapid or classical games occasionally to practice deeper calculation and decision making without extreme time pressure.
- Review your recent losses with a chess engine and identify recurring mistakes or missed opportunities.
- In bullet sessions, practice mindfulness about time management—try to avoid hasty moves especially when down on time.
- Incorporate endgame training puzzles to convert material advantages cleaner under time pressure.
Remember, consistent practice and reflection on your games, combined with expanding your opening repertoire and endgame knowledge, will bring steady gains over time.
