Oleg Vastrukhin
Profile
Oleg Vastrukhin, known on the board as demon64fields, is a FIDE International Master with a serious addiction to the Blitz clock. His favorite battlefield is Blitz, where he reached a peak rating of 3147 (2026-06-07). The username says it all: 64 fields of pure chaos.
Style of play
If you face Oleg, expect knights. Lots of knights. His first move is almost always Nf3, setting up a King's Indian Attack with g3 and Bg2. He rarely opens with e4 right away, but he loves striking with e4 later, leaving opponents guessing between the King's Indian Attack and a reversed French Defense.
His games are marathon battles. He averages over 86 moves per win and nearly 90 moves per loss, with a comeback rate of 88.35%. Even after losing a piece, he still wins around 41% of the time. He only resigns 14% of the time, and he plays his best chess at 9 in the morning, long before most rivals have finished their coffee.
A typical Oleg setup looks like this:
Favorite openings
His repertoire reads like a museum of rare and spicy lines. As White, he leans on the Hungarian Opening: Wiedenhagen-Beta Gambit and the Indian Defense: Przepiorka Variation. As Black, he stays loyal to the Modern Defense and the Caro-Kann Defense, and he scores a solid 51.5% in the French Winawer Advance when he wants to get serious.
Rivalries
Oleg plays everyone, and he plays everyone a lot. His most frequent foe is Igor Kovalenko, who has faced him 214 times. The record is one-sided: igorkovalenko leads 113 to 84. The same story repeats against Aleksandr Shimanov (141 games), Rudik Makarian (138 games), and Michael Roiz (127 games), all of whom hold winning records over him.
But against tapuah, Oleg finally gets revenge, leading 53 to 52. It is a small victory, but he will take it.
A grinder's journey
Volume is the real story. Oleg has more than 13,000 analyzed games on record, and his Blitz rating climbed from the 2800s in early 2023 into the 3100s by mid 2026. The path was never smooth. He once won 13 games in a row, then later lost 12 in a row, proving that even a demon can tilt.
