Rise of a Blitz Specialist
Lev Fainveits, known online as RezPlus, is a quintessential blitz warrior. From his first recorded games in 2013 at a modest 1366 rating to crossing the 2600 mark by March 2026, his journey is a marathon of rapid-fire chess. Lev's preferred battleground is unambiguously blitz, where he has amassed over 4,900 rated games and a career win rate hovering around 46%. His rating graph reads like a mountain range, with steep ascents and occasional valleys, but the overall trend is unmistakable: relentless improvement.
His blitz peak of 2620 (reached in March 2026) places him in the elite ranks of online blitz players. That peak came after a particularly explosive 2026, when he logged over 1,000 blitz games in a single year and pushed his rating through the 2500 ceiling repeatedly. While his bullet play is a side hobby (peak 1681), Lev clearly reserves his sharpest focus for the 3–5 minute arena.
Opening Repertoire: A Study in Variety
Lev is not a one-trick pony. His openings data reveals a deep and eclectic repertoire. As White, he favors 1.d4 with a strong affinity for the Queen's Gambit Declined and its many variations, particularly the 4.Bg5 Be7 5.cxd5 Nxd5 line, which he has played 158 times with a nearly even score. He also shows surprising comfort in the Benko Gambit, where his 57.8% win rate over 102 games indicates he enjoys dynamic compensation. As Black, he regularly meets 1.e4 with the Ruy Lopez: Brix Variation (221 games, 45.7% wins) and shows no fear of the Blackburne Shilling Gambit, a tricky line often seen in blitz. His deep preparation is evident in his median prep depth, which grew from 1 move in 2013 to 6 moves in recent years, allowing him to navigate complex middlegames with confidence.
A curious quirk: when facing the Döry Defense (typically an irregular Indian setup), Lev scores 100% in bullet but only 47.5% in blitz, suggesting he saves his best ideas for slower time controls. His most successful blitz opening overall is the Grünfeld Exchange, where he wins 57.8% of the time, often transposing from 1.d4 Nf6 lines.
The Grinder's Mentality
Lev's playing style is defined by relentless pressure rather than flashy sacrifices. He rarely resigns early (early resignation rate just 1.01%) and is a ferocious comeback artist, converting 86.6% of games where he falls behind. Even after losing a piece, he still wins 44.7% of the time, a testament to his resourcefulness and endgame skill. His average decisive game stretches to 78 moves, indicating that he grinds out victories in long, tense battles.
Notably, Lev's record against higher-rated opponents is respectable (26% wins, 62% losses), but he absolutely feasts on lower-rated players, winning 61.4% of such games. This makes him a feared opponent in open blitz pools, where he can rack up points relentlessly. His strength-adjusted win rate of 0.5004 in blitz suggests that he consistently performs at or slightly above his rating, a hallmark of a seasoned competitor.
Rivalries and Rivalries
Like any prolific online player, Lev has his share of frequent foes. His most-played opponent is edrocha10, against whom he has battled 14 times, holding a narrow 5–6–3 record. Another long-running rivalry is with zelimirjno (12 games, with Lev leading 6–3–3), while magicaaalz has felt Lev's sting in 7 of 11 encounters. He also has a perfect 5–0 record against westhercegovina, a friendly but one-sided series. These recurring duels add a personal layer to the rating grind, turning anonymous queues into familiar battlegrounds.
Lev's performance varies by day of week, with his best win rate on Fridays (47.6%) and Saturdays (47.7%), while Sundays are clearly his danger zone (44.7%). He seems to hit his stride in the early morning hours: his 53.3% win rate at 5 AM suggests that a cup of coffee and a silent house produce his sharpest calculations.
Rain or Shine
Lev's career has its share of turbulence. A brutal losing streak of 9 games in 2024 and a 2025 slump saw his rating dip to 2263, but he always clawed back. His longest winning streak is 8 games, which seems short given his overall volume, but this speaks to his consistency rather than volatility. He plays in streaks, often grinding hundreds of games in a month, with November 2025 being his most prolific month (123 games) and also the month he crossed the 2500 mark for the first time.
Off the board, Lev is clearly a lifetime learner. His early games from 2013 show a raw tactical player, but by 2026 his opening preparation is deep and his endgame technique is rock solid. He checks his opponent early (44.65% of the time) and uses that initiative to steer games into structures where he thrives.
The Bottom Line
Lev Fainveits may not be a household name in classical chess, but in the fast-paced world of online blitz, he's a force to be reckoned with. With over 4,900 blitz games played since 2013 and a peak rating of 2620, he embodies the modern chess enthusiast: dedicated, data-driven, and ever-improving. Whether you meet him as edrocha10 or any of his other rivals, expect a fight to the last move. As the saying goes, "Blitz is just chess with less time to overthink." Lev seems to have found the perfect balance.
