Siem van Dael (aka Siemba)
FIDE Master & Bullet Buff Extraordinaire
Meet Siem van Dael, better known in the online chess realms as Siemba, a FIDE Master whose bullet chess skills could probably make a superhero jealous. With a lightning-fast rating peak of 3006 in bullet chess—yes, you read that right—Siemba is living proof that speed and precision are not mutually exclusive.
Starting with humble beginnings around December 2017 with a bullet rating near 1670, Siemba has blitzed their way upward, crushing pieces and spirits alike, peaking spectacularly in 2023 with a bullet rating soaring past 2900. If bullet is the sprint, Siemba is Usain Bolt on the chessboard.
When it comes to openings, Siemba enjoys a good challenge. They seem to have a special relationship with the Caro-Kann Defense in bullet games, boasting a 69% win rate here – a cozy fortress where opponents often find themselves lost in the labyrinth. Meanwhile, the Classic Scandinavian and King's Indian Attack also feature prominently, proving versatility on the battlefield.
Playing Style & Psychology
With a penchant for endgames (played in over 71% of the games), Siemba is patient – they thrive in long duels where every pawn counts. Their average winning game clocks in around 68 moves, which suggests they are not just fast but also enjoy deep strategic tugs-of-war.
However, like all mortals, Siemba has a tilt factor of 15 – definitely someone who might grumble under their breath after a brutal loss. But fear not, their comeback rate is an impressive 78%, showing a fighter's heart that bounces back stronger than ever.

Recent Game Analysis
Siem, your recent blitz games show a solid understanding of openings but some opportunities for improvement in the midgame and endgame phases against strong opponents.
- In the game versus Daniel Yang with the Kings Indian Attack French Variation, you maintained good piece development and central control early, but the transition into the middle game saw you lose material after a critical exchange in the center. Improving calculation here can help avoid such losses.
- Against Miguel Lázaro Azcutia playing the Four Knights Game, you faced aggressive pawn advances and pressure on your kingside. Consider reacting more dynamically to opponent's aggressive moves and preparing for sharp pawn structures.
- The Van Geet Opening games indicate you are comfortable against uncommon openings but sometimes struggle with initiative and timely counterplay. Working on counter-attacking plans and king safety in unbalanced positions might boost your results.
- In general, your openings repertoire is well-rounded, and you often reach decent middlegame positions, but the losses suggest a need for sharpening tactical awareness and endgame precision.
Strengths
- Good knowledge and execution of a variety of openings including Sicilian Defense and Caro-Kann Defense.
- Solid positional understanding allowing you to reach balanced and playable middlegame positions frequently.
- Capability to contest complex positions and adapt against higher rated opponents.
- Consistent effort indicated by a near 49% strength adjusted win rate.
Areas for Improvement
- Tactical Calculation: Some recent losses involved material disadvantages from exchanges or tactical oversights. Training with puzzles focused on tactics under time pressure will help.
- Endgame Technique: Improving knowledge of basic endgames and practical conversion skills can turn close games in your favor.
- Midgame Planning: Develop plans to counter opponent aggression early, especially in openings like the Four Knights Game and Van Geet Opening where opponents tend to push aggressively.
- Time Management: Blitz games are fast-paced; balancing speed with accuracy is vital as some mistakes may stem from clock pressure.
- Mental Resilience: You have had a challenging rating trend recently, with a six-month dip. Staying focused and learning from mistakes will be key to reversing this trend.
Recommended Training Focus
- Daily tactical exercises emphasizing pattern recognition and calculation speed.
- Endgame study covering king and pawn endgames, basic rook endings, and common theoretical draws/wins.
- Analyze your recent losses to identify recurring themes or errors in calculation or strategy.
- Play slower time-control games where ideas can be tested more deeply and you can practice solid planning.
- Utilize game review tools and post-game analysis to deepen understanding and avoid repeated mistakes.
Encouragement
You have demonstrated strong opening preparation and have a solid base to build upon. Despite some recent setbacks, your ability to hold your own against tough opponents points to great potential. Keep focused on steady improvement by balancing tactical sharpening with strategic play, and the rating gains will follow.
Remember, every game is a learning opportunity–embrace the process, and progress will come.
