Sergiy Kryvosheya – The Chess Grandmaster Known as "skzt"

Sergiy Kryvosheya, better known in the chess world as skzt, holds the prestigious title of Grandmaster awarded by FIDE. A cunning tactician and fierce competitor, Sergiy has battled thousands of blitz games, achieving a peak blitz rating of 2580 in May 2020 and a bullet peak of 2588, making him a formidable opponent in fast-paced arenas.

Armed with a razor-sharp mind and an affinity for the “Top Secret” openings (really, the strategy is so classified even the opponents get confused!), Sergiy boasts a blitz win rate north of 62% across over 400 games. Whether it’s blitz, bullet, or rapid, his playstyle is aggressive yet calculated, with a remarkable comeback rate of 88.57% — so don’t be surprised if he turns a losing position around quicker than you can say "checkmate".

Often found online grinding ranked games, Sergiy shines brightest on Saturdays and at the early dawn hour of 7 AM (maybe fueled by some extra caffeine), winning over 71% of his games on Saturday and boasting over 81% win rate at 7 AM. If you catch him playing at that time, consider your king warned...

Despite the serious accolades, Sergiy has his fair share of ups and downs: a longest winning streak of 11 games and a darkest quintet of losses in a row—but hey, what grandmaster hasn’t had a nightmare streak where pawns just refuse to cooperate? His average game length hovers around 67 moves for wins, proving that this isn't a player who rushes to quick victories; every move is sifted through the mental sieve of strategy and patience.

Fans love his resilience, especially when he loses material — his win rate after losing a piece is an impressive 61.39%. That's right: take a piece from Sergiy, and you might as well brace for a fierce comeback. He’s known as the “tilt-resistant” player too, with a low tilt factor of 5, meaning he stays cool, calm, and calculating when the chips are down.

Some highlights from recent battles include...

  • A stunning victory in March 2025 over MateoVader2 using the Alekhine’s Defense Scandinavian Variation, sealed elegantly by resignation after relentless pressure.
  • A flawless checkmate in February 2025 against hrundel24, where Sergiy's tactic precision and timing turned the tides dramatically.
  • A nerve-wracking time victory in December 2024 against EdmundPlayer, proving sometimes the clock is as much a weapon as the queen.

Beyond the board, Sergiy’s expansive online opponent list and overwhelmingly positive win ratios against many players show a competitive spirit combined with an unwavering dedication to the art of chess.

If you ever see "skzt" blinking an extra time before making a move, don’t be fooled—that’s just Sergiy mentally setting the trap you’re about to fall into. Challenge him if you dare, but remember: in the world of chess, Sergiy Kryvosheya is a tactical storm wrapped in a grandmaster’s cloak.

Hi Sergiy (skzt)!

Congratulations on the steady climb to 2580 (2020-05-26) and a nice recent win in the Alekhine/Scandinavian hybrid (see the tactic below). Your games show a clear attacking flair and willingness to enter sharp positions, but there are a few recurring themes that—if polished—can push you to the next bracket.

What you’re doing well

  • Initiative-driven opening play. You frequently seize space with early ...c5/...c4 or Qh5/Bc4, forcing opponents to solve problems from move 1.
  • Tactical alertness. The exchange-sac in your latest game was timed perfectly:

  • Broad opening repertoire. With White you alternate between the Bishop’s, Queen’s-Pawn Zukertort and English setups; with Black you employ the Alekhine's Defense and Scandinavian, keeping opponents off balance.

Key areas to focus on next

  • Respect the “rating gap.” Both of your February games versus 596-rated hrundel24 illustrate a tendency to gamble against lower-rated players, leading to an unnecessary 1-1 split. Play the board, not the rating—convert cleanly instead of experimenting.
  • King safety in the middlegame. Early queen sorties (e.g., Qh5 on move 3) often leave you behind in development. Against stronger opposition (see losses to 2300-2600 range) you were punished by central counterplay. Consider delaying the queen until minor pieces are out.
  • Time management. Several losses were on the clock (e.g., vs. Tash_Boy). Try a discipline rule: reach move 20 with at least 40% of your starting time.
  • Endgame conversion. You generally reach winning endings but occasionally let activity slip (see 11/26 game vs. swop1107). A weekly diet of classical endgames (Capablanca, Karpov) plus practical rook-pawn drills will pay off quickly.
  • Defensive technique. When your attack is parried you sometimes overextend (loss to Euphonics2). Practice “best-defense” exercises: set up inferior positions vs. an engine and hold.

Action plan for the next 4 weeks

  1. Opening maintenance: pick two mainlines (one for each color) and review 15-move depth with a cloud engine. Add one completely new solid line to force yourself to play quieter positions.
  2. Tactics quota: 25–30 mixed-difficulty puzzles per day with 5-minute cap each. Focus on “defensive” tags, not just mating nets.
  3. Endgame Monday: each Monday watch one annotated model game that ends in a technical win; then reproduce the final position vs. engine until you can convert under 60 seconds.
  4. Sparring: play two 10|5 games daily using a strict “no pre-moves before move 15” rule to ingrain thoughtful pace.
  5. Self-review: after every session tag one critical mistake and one highlight. Build a mini database of “my recurring errors.”

Stick to the structure above, and your attacking style will be supported by reliable technique and clock control. I’m looking forward to seeing you cross 2600 soon—good luck!
