Rudolf Sertic (aka Rudus) - International Master
Meet Rudolf Sertic, an International Master who dances across the 64 squares with a blend of tenacity, strategy, and a dash of mystery—just enough to keep his opponents guessing (and occasionally running for coffee). Known in the chess world as "Rudus," Rudolf has crafted an impressive blitz career with a peak rating of 2471 in 2019, proving he's no stranger to lightning-fast decisions and razor-sharp tactics.
Chess Journey & Style
Rudolf's chess timeline is a thrilling rollercoaster: starting with daily games in 2008 with a near-perfect unbeaten streak, soaring through blitz battles where he notched a staggering 1694 wins out of 2899 games using his "Top Secret" openings (we suspect some secret sauce is involved). His endgame prowess is serious business — with nearly 80% endgame frequency, he grinds down opponents into submission with an almost philosophical patience.
Not one to surrender early (only 0.45% early resignations), Rudolf prefers the long haul—average games span over 73 moves, whether in victory or defeat, showcasing his tenacity and love for the deep strategic dance. Oh, and when life gives him a losing piece? He turns it around 100% of the time. Talk about turning lemons into castles!
Competitive Highlights
- Longest Winning Streak: 35 games. Yes, you read that right. The guy just doesn't stop.
- Current Winning Streak: 4 games and counting, presumably while writing this profile.
- Win Rates: Holds a phenomenal 58% win rate in blitz and a clean sweep in daily games at 100%.
- Psychological Edge: His comeback rate clocks in at over 90%, which might just mean never count Rudus out—even if you're up a piece.
Quirks & Trivia
Rudolf's favorite hours for crushing opponents? Early mornings where his win rate skyrockets to over 80% and evenings clocking in a solid mid-60s percent—proving he's equally deadly awake at dawn or dusk.
Warning to opponents: Rudus's tilt factor is 43, so if you catch him on a bad day, just don't. Unless you enjoy watching a firestorm on the chessboard.
Opponent Relations
Having tangled with “computer4-impossible” more than 100 times (and multiple human sparring partners as well), Rudolf boasts a mixed bag of win rates—some rivals get the full treat of his dominance, others slip away with a lucky draw or two. But make no mistake, Rudus is a formidable foe who respects no stale openings and treats every match like a grand finale.
Legacy
Rudolf Sertic isn't just a player; he's a chess connoisseur whose story is told through moves and matches, wins and woes, late nights analyzing and early mornings gaming. Whether you’re a fan or foe, his games offer a masterclass in grit, genius, and a little bit of that friendly madness that makes chess endlessly fascinating.
Hi Rudolf!
Congratulations on maintaining a high-2300 blitz level (2471 (2019-02-02)) and on a very healthy overall win-rate (
, ). Below is some personalised feedback based on your last few sessions.What you already do very well
- Opening depth as Black. Your French Defence (both the Tarrasch and Exchange setups) scores excellently. In the win against hannibal4 you followed main-line ideas (…c5, …e5, …Rad8) and obtained an ideal French dream-bishop on d6. Keep that repertoire—it clearly suits your style.
- Dynamic pawn breaks. The d4-d5 thrust in your King’s Indian–structure win versus andkul showcased good timing: you opened files only after your pieces were ready to occupy them.
- Converting long endgames. The 78-move rook-and-pawn ending you converted demonstrates patient technique—especially the switch between pushing outside passers and creating a mating net with Ra8#.
Primary improvement themes
- Clock management. Four of the last six losses were on time in roughly equal or slightly better positions. You often spend 25–30 seconds in familiar openings, then rush in critical middlegame moments.
Training plan:- Play a daily set of 1–2 games with an
increment(e.g. 3 + 2) and force yourself to stay above 1 min at all times. - During review, mark the first move where you dipped below the opponent’s time—what decision could have been made earlier?
- Play a daily set of 1–2 games with an
- King safety after pawn storms. In the French Exchange win you launched …h5/…g5 successfully, yet similar pawn pushes backfired in the Nimzo-Indian time-loss. The common thread: loosening squares f6 & h6 without a clear follow-up.
Checklist before advancing flank pawns:- Can the opponent open the same file first?
- Is my minor piece ready to occupy the square I am weakening?
- What is my worst-placed piece? Improve it before the pawn leaves home.
- Simplification when ahead on material. In several wins you kept extra material on the board and still played beautifully, but the clock sometimes caught you. When two pawns up, consider exchanging a set of pieces even if it feels “slow.” Remember the classic principle of two weaknesses.
Actionable drills for the coming week
| Day | Exercise | Time |
|---|---|---|
| Mon-Tue | Play 10 blitz games only with the White side of the French Exchange to practise handling symmetrical positions fast. | 30 min/day |
| Wed-Thu | Endgame sparring: rook + four vs. rook + three pawns. Focus on building bridges and cutting the king. | 20 min/day |
| Fri | Annotate your Nimzo-Indian loss (below) and write one alternative move for moves 18-25. | 45 min |
| Weekend | Tactics ladder; stop when you hit three consecutive wrong answers. | Until error |

Final thoughts
Your tactical vision and feel for dynamic play are already master-level. By shaving 10-15 % of think-time in the opening and tidying up pawn-shield discipline, you’ll convert even more of those slightly-better positions into effortless wins. Keep up the excellent work, and let me know how next week’s drills go!
