Mark Timmermans - International Master

Meet Mark Timmermans, or as the internet chess community fondly calls him, DeTimmerman. This chess maestro has earned the prestigious title of International Master from FIDE, proving that blundering pieces like pawns only happens to the amateurs—Mark blunders less than a ninja in a night fight!

From humble beginnings in 2013, where his Blitz rating tiptoed in at a modest 1312, Mark's journey looks more like a rocket launch than a slow climb. By 2014, he smashed through to a stunning 2412 in Blitz, and kept flexing those brain muscles to hit an even blistering 2835 by 2025 in Blitz. He’s the kind of player who plays so fast and strong, even time feels threatened.

Mark’s Bullet chess stats paint him as a speed demon — with peak ratings of nearly 2900! It’s said that Mark’s fingers have their own Wi-Fi connection, as those quick moves dazzle opponents before they’ve even realized the game started.

Not just a quickshot, Mark enjoys the thoughtful pace of Daily and Rapid chess, with a consistent win rate above 70% in Rapid and nearly 90% in Daily games. His strategic prowess and calm under pressure mean he often wins without even breaking a sweat.

Playing Style & Personality

Legend has it that Mark once resigned early in a game... just as a joke. His Early Resignation Rate is a humble 0.12%, and his games typically span over 80 moves per win, showing that he enjoys to milk every positional squeeze and tactical nuance. His endgame frequency (85.88%) would make any rook or bishop blush with pride. A true chess marathoner!

Tactically, Mark is nothing short of Houdini: his Comeback Rate is a jaw-dropping 90.44%, and if he loses a piece, you better run for cover — his win rate after losing a piece is an incredible 100%. Talk about turning disasters into delights!

The Opponent Whisperer

Mark has faced a legion of chess combatants, including stalwarts like chessshop (75 games) and khatanbaatarbazar (37 games). His record shows a ruthless streak and uncanny opponent-reading abilities, with several 100% win rates against tricky rivals like sadykov_ramil, gmfrankenstein-dracula, and jessekraai. You’d think he’s got a crystal ball hidden behind those glasses.

Fun Fact

Mark’s current winning streak stands at zero — but don't be fooled: his longest winning streak is a magnificent 20 games in a row. That’s basically like winning every chess match at your local cafe while casually sipping a coffee. Coffee by day, chess by night!

His favorite time to play? When most are busy eating lunch or winding down before bed — hours like 6 AM (77.78% win rate) and 2 to 5 AM (some hours at 83% to 100% win rates!). Clearly, Mark is a night owl who breeds brilliance in the quietest hours.

Summary

With a brutal combination of tactical wizardry, sharp intuition, and a deadly fast mouse-hand, Mark Timmermans embodies the spirit of competitive chess. Whether blasting through Bullet games or squeezing out wins in marathon Daily battles, this International Master’s journey is far from over. Opponents beware: DeTimmerman comes to play, and sometimes he even lets you think you have a chance!

Hi Mark, here’s some targeted feedback based on your recent games.

What you’re doing well

  • Consistent Opening Repertoire – Polish / Larsen-type systems. Your familiarity lets you blitz out the first 10-12 moves quickly and reach middlegames you understand.
  • Piece Activity. In your wins you repeatedly seize space with pawn levers (a4, c4, d4) and place knights on outposts (Nd4, Nc6, etc.). The diagram below from your latest victory shows excellent piece harmony:

  • Practical End-game Technique. Several wins were converted in low time vs strong opposition – good “flag-hunting” instincts.

Patterns holding you back

  • Sensitive King Safety as Black. In the loss to Matvey Galchenko the g- and h-files collapsed after 13.g4. Your …g6/…Bg7 setup invites pawn storms; consider mixing in …e5 lines or earlier …h6 to blunt Bg5/Bh4 ideas.
  • Tendency to Over-press with Pawns in the Polish. In several defeats (e.g. vs “0817chess”) the early b4-b5, a4, g4 thrusts left weaknesses on c4 & e4 that opponents exploited. Aim to develop before pushing all the flank pawns.
  • Conversion against stubborn defence. When an edge fizzles you often drift into worse rook endings (see loss vs KRAT0S_GOW). Technique drills on Lucena and Philidor positions will pay dividends.
  • Clock Management in unclear positions. Your average remaining time at move 25 in losses was 0:45 vs 1:25 in wins (sample of last 10 games). Slow down when the position first leaves book.

Quick Wins for the next 2 weeks

  1. Add one mainline response as Black. vs 1.e4 try the solid …e5 Italian/Two-Knights you already use, but study the critical 9.Nd5 line (your game vs KRAT0S_GOW). A single evening with an engine will plug that hole.
  2. Daily 10-minute tactics set. Focus on forcing sequences & the concept of the Zwischenzug which cost you material in multiple games.
  3. End-game flashcards. Alternate rook+pawn vs rook endings every other day. Reproduce the key setups from memory.
  4. Play two games per day in a slower pool (5|5 or 10|0). For each, annotate one critical moment where you spent <10 seconds but should have paused.

Medium-term Study Plan (1–2 months)

WeekMain FocusMetric
1–2King-side Fortress drills (castle-side pawn structures)Save 2/3 games where you’d previously been mated
3–4Semi-open pawn breaks in Polish (…e5 vs b4)+10% score with White vs 2200–2400

Motivation Corner

Your current peak is 2907 (2020-10-28). The data shows you win most between 19:00–21:00 local. Use the dashboard below to track performance and schedule sessions in that window:

If you rematch francyIM, revisit the Bxa6 exchange sacrifice idea – it scored brilliantly (see diagram earlier). A direct link to their profile for scouting:

Final Thought

“Good positions don’t win games – good moves do.” Keep converting your dynamic setups into concrete advantages, and that 2800 blitz ceiling will fall.

Good luck with your training – looking forward to seeing the progress in your next set of games!
