Meet Dmitry Semenenko
Dmitry Semenenko, known online as semchik90, is a National Master who has turned online chess into a marathon of creative aggression. He has played tens of thousands of rated games, amassed more than 11,000 bullet wins, and once ripped off a 42-game winning streak that sounds like a typo.
Behind the username semchik90 is a player who never seems to run out of ideas. His journey from casual online play to a feared National Master profile is written in long winning streaks, improbable comebacks, and an enormous opening book.
A Bullet Machine
Dmitry is at his most dangerous when the clock is screaming. His bullet games are pure adrenaline, with a huge volume of wins and a peak rating that reached elite territory. He does not just survive in time scrambles, he hunts.
Opening Repertoire and Style
With White, Dmitry almost always reaches for 1.Nf3, the starting point of the flexible Réti Opening. He has faced the King's Indian Defense thousands of times from the White side and knows its typical plans by heart. As Black, his trusted weapon is the Alekhine Defense, a provocative opening that invites opponents to overextend and then punishes them for it.
Dmitry is a long-game player at heart. His wins average around 69 moves, and he reaches the endgame more than 80% of the time. In Rapid chess, his Réti Opening has produced a scary score above 96%, showing that he can be just as clinical when the clock is generous.
Daily Chess and Slow Precision
Even though he shines in bullet, his preferred time control is Daily. The numbers explain why. His strength-adjusted win rate in Daily chess is nearly 65%, and his Daily record is a tidy 85 wins against only 7 losses. He is the kind of player who keeps calculating even when he has a full day to think.
Rivalries and Resilience
Dmitry has built a collection of long-running online rivalries. He has faced nkitanas an incredible 154 times, winning 149 of those meetings. Other frequent opponents like Biculi have managed a more competitive record, but even they spend most of their evenings staring at a losing position.
His comeback rate of 78.56% means opponents can never relax. Even after losing a piece, he still wins roughly half of his games, a statistic that must haunt anyone who thinks they have outplayed him.
The Human Side of semchik90
Nobody is a machine, though. Dmitry has a longest losing streak of 10 games, proof that even National Masters have rough nights. He also plays best in the small hours, with win rates above 65% between midnight and 3 AM.
The overall picture is clear. Dmitry Semenenko is a relentless, tricky, and wildly prolific online competitor. He gives check over three times per game, is first to deliver check in 58% of his games, and converts those games at a 60% rate. Combine that with a 42-game winning streak and a nearly spotless Rapid record, and you have one of the most entertaining profiles on the platform.
