Jipsos: Caro-Kann and Amazon Attack Player with a Midnight Habit
Jipsos is an online chess player whose career spans from August 2018 to early 2025, peaking at a rapid rating of 1451 (2022-09-06) in September 2022. The player has competed across rapid, blitz, bullet, and daily time controls, with rapid clearly being the preferred arena. Total career record across all formats: 679 wins, 590 losses, and 41 draws.
The identity behind the username remains elusive, but the heavy Caro-Kann setup, Amazon Attack repertoire, and a statistically demonstrated affinity for playing at midnight strongly suggest a European nocturnal grinder. The current losing streak of seven games hints at a rough patch still in progress.
The Early Grind, 2018 to 2020
The record book opens in August 2018 with simultaneous blitz and bullet activity in the low 500s and rapid at roughly 918 before dropping to 610 within days. These were clearly exploratory games, sampling everything from the English Opening to the Scandinavian Defense to a single appearance of the Batavo Gambit.
2019 brought a slow rapid climb to around 746 by year's end. Blitz activity was heavier at roughly the 900-1000 level, and the peak blitz month reached 1114 in May. The Caro-Kann Defense started to make regular appearances as a Black defense, and the Australian Defense appeared for the first time.
2020 was quieter, with rapid in the 800-950 range and a January blitz peak of 1135. By the end of the year, Jipsos was sitting around 921 rapid, quietly accumulating the experience needed for what came next.
The 2021 Breakout: A 700-Point Rapid Leap
January 2021 changed everything. The rapid rating rocketed from 984 to 1265 in a single month, and 91 games were played with 55 wins. February added another 66 games and pushed the rapid mark to 1404. March 2021 brought a monthly peak of 1428 rapid, making Jipsos a fully fledged 1400-level player almost overnight.
Bullet also saw significant activity in February, reaching a career peak of 1233, while blitz topped out at 1153 in March. The annual average game length for 2021 was nearly 65 moves, and the median prep depth rose to 3, suggesting deeper preparation than in earlier years.
Peak, Slump, and a 2025 Comeback
The overall rapid peak of 1451 (2022-09-06) came on September 6, 2022, when Jipsos briefly touched 1451 before settling back around 1395. The year ended at roughly 1365.
2023 was sparse, with only a handful of games in the rapid and blitz formats. The rapid rating drifted between 1209 and 1402. 2024 was even quieter, with three rapid games total and a closing rating of 1239. But then, in December, daily chess made a surprise entrance with two games at the sub-650 level.
January 2025 roared to life. Twenty-two rapid games brought the rating to 1384. Blitz crossed above 1000 with seven games. Bullet played into January at over 900. Daily peaked at 914 on January 9. The trajectory is encouraging even if the seven-game losing streak currently in evidence suggests the engine is still turning over.
Playing Style, Openings, and Repertoire
Jipsos is a Caro-Kann specialist. The defense has been played in 59 rapid games at a 57.63% win rate, 38 bullet games, and 116 blitz games. The Caro-Kann Exchange Variation and Classical Variation also saw some play.
On White, the Amazon Attack is the anchor, appearing in every time control with a particularly strong rapid Siberian Attack line at 8 wins from 10 games. The London System Poisoned Pawn Variation rounds out the main White repertoire, alongside the Australian Defense and occasional Scotch Game forays.
The blitz repertoire is more eclectic, featuring the Elephant Gambit, the Amar Gambit, and the Scandinavian Defense with a solid 63.64% blitz record for the latter. The bullet Amar Gambit, however, is a genuine sore spot at just 3 wins from 14 games.
The daily repertoire, built on just 17 games, includes the Barnes Opening: Walkerling, Dresden Opening: The Goblin, Barnes Defense, Slav Defense, and a single Nimzo-Larsen Attack: Classical Variation.
- 55.34% endgame frequency, indicating a preference for grinding simplified positions to a conclusion.
- Average first capture at move 5.9, making Jipsos a fast developer.
- White win rate at 54.42% clearly beats Black at 49.24%.
- Comeback rate of 70.1%, which is genuinely elite and suggests a refusal to resign even in lost positions.
- Tilt factor of 8 and a best-play hour at midnight reinforce the nocturnal grinder image.
