Velislav Kukov (aka Velis23)
International Master | Blitz Maestro Extraordinaire
Meet Velislav Kukov, a chess warrior with the prestigious title of International Master bestowed by FIDE. Known in the chess realm as Velis23, Velislav has over the years turned countless blitz battles into stunning victories, proving that lightning-fast moves and deep strategic insight are not mutually exclusive.
With a blitz peak rating soaring to an impressive 2651 in January 2025, Velislav has mastered the art of thinking several moves ahead even when the clock ticks away mercilessly. His gameplay is a beautiful dance between patience and aggression, averaging nearly 77 moves per win, showing endurance alongside speed.
His rapid chess skills are no joke either — peaking at 2508 — and while bullet games might be his occasional playground, his blitz performances are what truly make him a formidable force. Having played over 7,926 blitz games with a solid win rate around 50.66%, Velislav clearly enjoys the thrill of quick calculations and sharp tactics.
Playing Style & Mental Toughness
- Excellent at endgames, appearing in 85% of his matches — a true grinder until the very end.
- Prepared to make a comeback, boasting a comeback rate of nearly 87% — never counts himself out.
- Known for his cool-headed approach, with a tilt factor of just 8, Velislav rarely lets emotions cloud his judgment.
- Prefers to reserve early resignation for truly hopeless situations — only 0.37% of games.
Fun Fact
If you think chess players only get better with age, Velislav is a shining example: starting with a blitz rating of 1374 in 2014, he steadily climbed the ranks to a sharp 2600+ rating, all while adeptly handling time pressure and threatening his opponents’ kings from all angles. He even sports a secret weapon opening aptly nicknamed "Top Secret," which has netted him thousands of games, wins, and a reputation for keeping opponents guessing!
Recent Highlights
Just in May 2025, Velislav secured a thrilling blitz victory in a Caro-Kann Defense battle against Nemus7, winning by time with some precision moves — demonstrating that even when the clock is the enemy, it’s still all about the moves on the board.
Sure, like any grandmaster, he has his share of losses, but Velislav's strategic resilience and fast reflexes keep him bouncing back stronger and faster. Whether it’s a checkmate or a crafty time win, this International Master plays to win, making every game a story worth telling.
Hi Velislav! 🎯 Quick snapshot
• Current personal best: 2651 (2025-01-14)
• Preferred defences: Caro-Kann, solid Queen’s-pawn lines
• Typical game length: 45-55 moves • Average time spent per move: 2-3 s
What you’re already doing well
- Opening variety inside a single structure. You switch between 3…Bf5 and 3…c5 in the Caro-Kann and already know the modern …h5 idea (seen versus Denis Trifonov). This keeps opponents guessing while staying in your comfort zone.
- Early queen exchanges to reach favourable endgames. Your wins against FizzyBand and Salimskyi show clean conversions once queens come off.
- Active rook play. You rarely leave rooks passive; the double-rook pressure on the d-file in the Nemus7 game is textbook.
Key areas to polish
-
Clock management – the recurring nemesis.
Five of your last seven losses were decided only by the flag. Consider:
- Using premoves in forced recaptures when the position is stable.
- Setting a mental “5-second rule”: if nothing tactical is hanging, move and keep 5 s in reserve.
- Practising increment drills (30 s vs engine) so you feel how little time is really needed to maintain quality.
-
Over-extension of flank pawns.
The early …h5 versus everything sometimes hands White a ready-made hook (see your loss to harrisonchess21 where 16.g4! undermined the entire kingside). Ask yourself: “Does pushing this pawn improve a piece right now? If not, keep it.” -
Handling queen-side space grabs as White.
In the Benoni loss to KarlOnegin you played 20.Nc5?! and soon allowed …b4; the knight looked pretty but achieved little. When you seize space withb4 / c4, follow up witha4or rook lifts so the pawns don’t become static targets. -
Technical rook-pawn endings.
Games against SchroedingersTiger and harrisonchess21 reached drawable rook-vs-pawn or king-and-pawn endings but slipped away. Spend a session on the “Philidor” and “Vancura” draws; they appear often at your level.
Middlegame pattern to replicate
Note how you first fixed Black’s structure with 5…h5, then out-posted the knight on e5 and finally used gxf3 to open files. Aim to recreate this “induce-fix-break” sequence more often.
Action plan for the next 4 weeks
| Week | Main focus | Micro-goals |
|---|---|---|
| 1 | Clock discipline | Play 20 blitz games limiting yourself to <5 s on any single move. |
| 2 | Rook endings | Solve 30 studies featuring Vancura & Philidor setups. |
| 3 | Anti-g4 systems vs Caro-Kann | Build a mini-repertoire with …h6/…g5 lines; annotate three model games. |
| 4 | Queen-side space as White | Review your own Benoni & KID structures, create 5-move plans after b4/c4. |
Final encouragement
Your tactical alertness is already 2600-level; smoothing the non-chess factors (time, routine endgames) will push your rating ceiling higher than your current 2651 (2025-01-14). Keep the fighting spirit, and see you soon on the board!
