Marc Morgunov (aka Kolle05)
FIDE Master Extraordinaire
Meet Marc Morgunov, a formidable chess virtuoso armed with the prestigious FIDE Master title. Marc doesn’t just play chess — they dominate the 64 squares with a blend of tactical genius and stubborn resilience that can make even grandmasters sweat.
Marc's blitz rating has sprinted from humble beginnings around 1000 to an electrifying peak of 2668 in November 2023 — a number that demands both respect and at least a little fear from opponents. When playing bullet, Marc rockets to a stunning 2558, proving speed is no problem when every move counts.
Known affectionately online as Kolle05, Marc has racked up over 1100 wins in blitz chess alone, with a penchant for dissecting opponents using openings like the Sicilian Defense and the Caro-Kann Defense. Their rapid style is no slouch either, peaking over 2300, and the wins they gather in rapid games exhibit their deep understanding of strategy over time.
Marc's gameplay is like a thrilling novel — averaging more than 70 moves in victories, showcasing patience and steadfastness in endgame battles (endgame frequency near 80%). As if immune to discouragement, they boast a comeback rate over 83%, turning lost positions into wins with the grace of a phoenix rising from the ashes. Early resignation? Not their style; Marc sticks till the last piece drops.
The psychological trench warfare of chess reveals another charm: a “tilt factor” of 7. It means Marc might get a little squirrelly under pressure, but hey, nobody’s perfect. Interestingly, the best time to catch Marc’s genius is at the stroke of 3 AM, when the mind is at its most mysterious and the queen most dangerous.
Recent Highlights

So, whether you’re a casual player hoping to learn, or an opponent bracing for battle, Marc Morgunov (Kolle05) is a name that means serious chess. Approach with respect, and maybe some luck.
Blitz strengths you can build on
You show a strong willingness to enter sharp, tactical play and keep the pressure on opponents. In many games you spot forcing moves and create complications that test your opponent's nerves. Your ability to stay active with active piece play in dynamic positions often yields practical chances, especially when your opponent missteps under time pressure.
Key areas for improvement in blitz
- Time management: in blitz, misallocating time leads to late blunders. Practice a simple thinking routine: spend a fixed amount on the opening move choices, then switch to a clear plan for the middlegame, and reserve a portion of your clock for endgames.
- Blunder prevention: build a quick “blunder check” into your process. After choosing a candidate move, pause for a second to scan for tactical threats, hanging pieces, or obvious forks from the opponent.
- Endgame conversion: several games slip in the later phase. Strengthen basic king-and-pawn endings and small-piece endgames so you can convert which you’re winning, even when time is short.
- Middlegame planning under time pressure: cultivate a simple plan in typical structures (for example, target a weakness, open a file/bullet, or create a pawn break) rather than trying to calculate every branch.
- Consistency across longer horizons: the longer-term trend suggests there’s room to stabilize performance. Aim to translate short-term momentum into steady, repeatable decisions.
Opening strategy and repertoire (practical focus)
Blitz benefits from a compact, practical opening repertoire. Pick 2–3 White responses and 2–3 Black defenses that you understand well and where you know the typical middlegame plans. This reduces decision fatigue and helps you reach clean middlegames more often. Consider simplifying your choices to prioritize clear plans over deep, risky lines. Examples you may explore include a solid e4 setup and a robust d4 setup, with dependable replies as Black to those openings. Caro-Kann Defense and Sicilian Defense can serve as anchors in your study to reinforce solid, plan-oriented play.]]
Training plan to elevate blitz results
- Daily tactical practice: 10–15 minutes of timed puzzles to sharpen calculation under time pressure.
- Post-game reviews: after blitz sessions, identify 2–3 critical moments where a small improvement could have avoided a loss or blunder.
- Endgame basics: dedicate 15 minutes a week to simple endgames (king and pawn against king, or rook endings) to boost conversion in tight clocks.
- Blitz-specific routines: simulate 3+2 or 2+1 blitz sessions with a quick self-check to reinforce your opening plan and early middlegame strategy.
- Opening refinement: adhere to a focused short repertoire and add 1 or 2 typical middlegame plans for each line so you can execute faster in real games.
Progress tracking and concrete next steps
Set a two-week target to implement the above routines. Track three metrics each session: average time spent in the opening, number of blunders per game, and success rate in the middlegame conversion. After two weeks, review which openings consistently reach solid middlegame positions and which endings you convert most reliably, then adjust your repertoire accordingly.
Optional practice enrichment
If you want a ready-made example for focused study, you can explore a compact opening line set such as a simplified Caro-Kann or a controlled Sicilian line. See placeholder resources for targeted opening concepts: Caro-Kann Defense and Sicilian Defense.
