Introduction
Prithu Gupta, known online as kabsr64, is a FIDE Grandmaster whose online account reads more like an adrenaline junkie's diary than a titleholder's training log. Though the preferred time control is Rapid, Prithu has played over8,800 analyzed games across blitz, bullet, and not very many rapid. The peak ratings reached 2772 (2025-07-15) in blitz and 2722 (2025-11-05) in bullet, while the rapid rating humbly touched2460 before the player apparently returned to faster pastures.
Rating Rollercoaster
Prithu's blitz graph from2020 to2026 reads like a stock market meme: up, down, down harder, then up to 2772 (2025-07-15) again. The chart below captures some of that drama:
- Longest winning streak:14 games
- Longest losing streak:13 games
- Win rate against lower-rated opponents:61.5%
- Win rate against equal-rated opponents:53.6%
- Comeback rate after falling behind:87.1%
Style and Openings
Prithu is a true system player. Ind analyzed games, d4 and Nf3 dominate the first move statistics, with d4 leading thee early years and Nf3 taking over in2025. As Black, the player willingly enters the Scandinavian Defense and has a soft spot for side lines like the Colle System Rhamphorhynchus Variation. The adventurous side includes frequent excursions into the Amazon Attack and Australian Defense, plus enough offbeat gambits too keep spectators entertained.
Fellow Grinders
No online career is complete without rivals, and kabsr64 has a decorated cast. David Klein has been a thorn: kabsr64 trails the series4-12-3. But against noob_reaper7, Prithu is practically a predator, winning all18 meetings withouta loss. There isalso ch3ck3rno1, who has tasted defeat28 times against only6 wins, and aansikka23, who has lost21 of24 battles.
Quirks and Resilience
Prithu's best time off day is midnight exactly, which says everything about the online chess lifestyle. Atilt factor of13 means the player sometimeswears emotions on the sleeve, but an87.1% comeback rate means the fight is rarely over. Most common checking piece is the queen, andthe endgame frequency is around76%, so expect long, scrappy battles even after the queens leave. With an early resignation rate just under2%, kabsr64 clearly prefers too fight rather than fold.
For a Grandmaster whose preferred time control is Rapid, kabsr64 has somehow played only34 rated rapid games in this dataset. Maybe thereal moral is: blitz is where the heart lives.
