Hristo Ivelinov: The Midnight Marathoner
Some people play chess. Hristo Ivelinov, known on the board as hristoivelinov, is in a long-term relationship with it. Since arriving on the online chess scene in May 2017, he has played more than 7,000 blitz games, climbed from a humble sub-1000 debut to a career-best blitz rating of 2403 (2025-04-25), and proved that persistence, a well-worn Scandinavian Defense, and a suspicious fondness for 11 PM can carry a player a very long way.
Technically, his listed weapon of choice is bullet chess, and with a bullet record of 10 wins, 1 loss, and 1 draw you can see why. But the blitz catalog is where the biography lives. The arc is pure grind: over 2000 within weeks of his first game, parked lovingly in the 2100 to 2300 corridor for half a decade, then a breakout run in 2025 that pushed him past 2400. Eight years of momentum, zero shortcuts.
The Opening Repertoire: Old Friends and One Giant Prank
Ask Hristo for a surprise and you will not get one. You will get the Scandinavian Defense, his most played opening by a country mile, or the Czech Defense against 1.d4, a setup as sturdy as it is unglamorous. When he is feeling spicy, the Sicilian Defense comes out to play.
- Scandinavian Defense: nearly 480 blitz games of daily bread, steady wins, zero apologies.
- Nimzo-Indian Leningrad Variation: his best friend as White, winning over 61 percent of the time.
- King's Indian Defense: Averbakh Variation: close to 63 percent wins. At this point the Averbakh Variation is basically Hristo with a different name.
- Gruenfeld Exchange Variation: his sharpest White weapon at 65 percent. This is where the scalpel comes out.
- London Poisoned Pawn Variation: he lets you build your dream setup, then calmly eats the pawn. Over 55 percent wins doing it.
- Amar Gambit: as Black, 82 games at a 65 percent win rate with an opening most theory books treat as a punchline. Hristo does not read the punchline. Hristo wins.
Rivalries and Rituals
Every grinder has a recurring cast, and Hristo's is colorful. His record against D3rm0chelys across 30 games reads 28 wins, 1 loss, and 1 draw, which is less a rivalry and more a subscription service. faresbylka provides honest fights at 12 wins to 5 losses, while ferrooo10 leads their head-to-head 11 to 7, living proof that even a blitz shark has someone who bites back.
And then there is moazim: 15 meetings, only 3 Hristo wins. Every hero needs a kryptonite, and Hristo's apparently walks around rated blitz with a username.
Style: The Comeback Clock
The numbers paint a very specific portrait. Over 77 percent of his games reach an endgame, his average win runs about 65 moves, and after dropping a piece he still wins roughly half the time. If Hristo is down material, the game has not gone wrong. The game has simply started.
- Comeback rate: 84 percent. Losing a piece is a rounding error to this man.
- One-sided loss rate: under 1 percent. He does not do blowouts in either direction.
- Early resignation rate: 62 percent. When it is over, he lets you go home. A gentleman.
- Longest winning streak: 12 games. Longest losing streak: 10. The tide always turns.
- Favorite checking piece: the queen, with nearly 7,000 royal inspections delivered.
One confession: the clock has beaten him more often than any human ever has, with nearly 1,400 defeats on time. The flag is his true nemesis, and unlike his other rivals, it never needs a break.
Circadian Chess Science
Here is the part that should genuinely worry his opponents. Hristo's best hour is 11 PM, where he wins over 62 percent of his games. The hours on either side of midnight crater into the low 40s. Devastating right before bed, pumpkin shortly after. Mondays are his strongest weekday, and weekends are reserved for, presumably, anything but sharp opening preparation.
There is also exactly one rapid chess footnote: a single loss to the Amar Gambit. The blitz version of that same opening has healed that wound many times over, which is the most Hristo sentence in this entire profile.
