Oleg Kozlov (VAT55)
International Master of Chess
Meet Oleg Kozlov, an International Master whose blitz skills light up the board and give grandmasters a run for their money. Known in the digital chess realm as VAT55, Oleg is a fierce tactician with a penchant for endurance and a strategic mind sharper than a knight’s fork.
Over the years, Oleg's blitz rating has soared to a mighty peak of 2737 in April 2025—enough to scare even the most hardened bullet specialists. Speaking of bullet, he also hit a blistering top score of 2737, proving he's just as comfortable playing at lightning speed as he is in tactically complex positions. And let's not forget his rapid peak of 2224, making him a well-rounded threat across all fast time controls.
Oleg is fond of the mysterious "Top Secret" opening—perhaps because he likes to keep opponents guessing until it's too late! Despite his playful style, his average game length hovers around 76 moves, showing that he loves a good fight to the very end, often exhausting his foes by outmaneuvering them in the endgame with notable frequency (78.24% of his games).
Psychological resilience? Check! Oleg has an impressive 82.15% comeback rate after setbacks, clearly embodying the spirit of a chess warrior who never gives up—even when the odds are stacked. His tilt factor of 10 means he occasionally gets frustrated, but hey, who doesn't when your opponent pulls out a sneaky sacrifice?
His preferred battlegrounds are when the clock reads "early morning" – around 4 AM – a time when many mere mortals sleep, but Oleg sharpens his wits and polishes his openings. His win rates peak at unusual hours and days, defying the typical "office hours" stereotype.
A look at his recent encounters reveals exciting victories, such as a brilliant blitz win against NMBraveheart0820, where he executed a precise kingside attack culminating in a clean finish on time. Losses? Only a few, often to highly rated adversaries—not enough to dampen his fighting spirit.
Stats at a Glance:
- Blitz Record: 1606 wins, 1758 losses, 190 draws
- Bullet Record: 91 wins, 61 losses, 6 draws
- Rapid Record: 12 wins, 8 losses
- Longest Winning Streak: 12 games
Whether it’s wielding the King's Indian Defense with the flair of a grandmaster or surprising opponents with a Top Secret line, Oleg Kozlov’s games blend tenacity, creativity, and endurance. Don’t be fooled by the calm exterior – behind those calculated moves is a player ready to laugh in the face of checkmate… just before delivering one of his own.
“Chess isn't just a game; it's a battlefield where wit meets willpower, and Oleg Kozlov is a general who knows how to make every pawn count.”
Oleg, great fighting spirit!
You have been hovering around 2737 (2025-04-29) with a very respectable tactical awareness. Your recent victories show both creativity (the g3–Bg2 double-fianchetto setups) and excellent conversion technique in technical endings. Below are a few focused remarks to help you climb to the next tier.
What you already do well
- Opening variety & understanding. You comfortably switch between the King’s Indian Fianchetto and Closed/Grand Prix Sicilians, often steering play into middlegames you understand better than your opponents.
- Counter-punching under pressure. In your win over NMBraveheart0820 you calmly absorbed Black’s queenside play and then seized the initiative with 24.Nxb5! and 28.b5!, taking over the c-file.
- End-game persistence. The game against Mikhal867 shows solid technique: you activated the king early and kept the passed pawn rolling until the flag fell.
Key areas for growth
1. Time management
Five of your last seven losses featured <10 seconds on your clock by move 35. Even when you are slightly better you slip into “panic-pre-move” mode and accuracy drops.
- Use the first 10–15 moves to bank time, not to spend it. If you know the position, move instantly.
- Adopt a “minimum 15 seconds” rule: when the clock first dips under 15 s, liquidate tension or simplify.
- Train in 5 | 5 or 10 | 0 sessions to practise calculating without perpetual time trouble.
2. Pawn-storm discipline when behind in development
Your loss to Hans_L4145 began with the enthusiastic 5.h4 6.g4 7.g5—but the queen-side pieces were still asleep. Once Black broke with …c5 you had no king safety.
Guideline: “Three minor pieces developed before launching a flank pawn storm.”
3. Dutch/Leningrad structures as Black
The defeat against DvaHrasta revealed hesitation in typical Leningrad plans. You played the correct thematic …f5 and …d6, but missed:
- …e5 break after …Re8 instead of the slow …Qe8–c8 maneuver;
- timely queenside counterplay with …c6–d5, freeing the dark-square bishop.
Suggested drill: annotate 3–5 games by established Leningrad specialists (e.g. Malaniuk, Kramnik) and identify recurring move orders.
4. Tactical clean-up
A handful of tactical oversights still creep in, often connected to loose pieces on opposite wings. Adding 20–30 puzzles/day filtered for “very hard” motifs (double attack, deflection) will reinforce pattern recognition.
Quick homework plan
- Re-play move 20 onward of the Hans_L4145 game and note every move that gave your opponent an uncontested tempo (tempo).
- Solve 50 end-game studies this week; focus on king activity.
- Build a mini-repertoire file of 10 critical Dutch/Leningrad tabiyas with best plans on both sides.
- Play a 10-game set of 10 | 0 to practise staying above 60 seconds by move 25.

Keep the momentum!
You are already on the cusp of master strength. Polishing time usage and tightening early-pawn adventures will add 50–70 rating points quickly. Stay confident and keep analysing your own games—especially the losses.
Good luck in your next Titled Tuesday run, and remember: “Solid first, creative later.” I’m here whenever you need another review.
