Shubham Kumar (shubhu413) - The Chessboard Biologist
Shubham Kumar, known online as shubhu413, is quite the fascinating organism in the wild ecosystem of chess players. Having evolved through the seasons since 2021, Shubham’s Blitz ratings have been on a curious journey: from a robust peak of 732 to a recent sturdy recovery at 372 in 2025. His Rapid games, though fewer in number, demonstrate bursts of genetic brilliance with a peak rating near 1179 in 2021.
A Tactical Genome
Shubham exhibits an impressive comeback rate of 51.85%, showing his ability to regenerate and adapt even after losing key chess pieces – with a remarkable 100% win rate after such setbacks, like a biological phoenix rising from the ashes of a sacrificed pawn. This resilience counters his tilt factor of 11, meaning he keeps his cool most of the time without succumbing to the psychological viruses that plague many players.
Opening DNA and Style
His opening repertoire is diverse, with notable success in the Van t Kruijs Opening (winning over 60% of those encounters) and solid performances in classic defenses like the Caro Kann and Scandinavian. Shubham demonstrates a patient metabolism during wins and losses alike, averaging around 45 moves per game, showing a stamina worthy of a chess marathon runner.
Interestingly, Shubham tends to win more often with the white pieces (48.76%) than black (43.32%), perhaps suggesting a slight preference for Hox gene expression on the light squares of the board. His endgame frequency of nearly 40% reveals a fondness for the late-stage DNA replication of games, where precise moves decide the evolutionary fate of each match.
Behavioral Patterns & Psychology
Analysis of his activity shows he thrives during twilight hours, with peak win rates at 13:00 and impressive spikes late at night (22:00 boasts a flawless 100% win rate, though likely from a small data sample!). His win rates are reasonably stable throughout the week, proving that the circadian rhythms of chess metabolism keep him consistent, avoiding major fluctuations or "tilt mutations."
Opponent Ecosystem
Shubham’s opponent record is a mixed gene pool with some prey that always elude his clutch and others who fall victim to his strategic claws. His longest winning streak of 7 games is a testament to a period of rapid cell division – or in his case, rapid tactical domination! The diversity of opponents reveals a species comfortable adapting against various playing styles and opening habitats.
In Conclusion
To study Shubham Kumar's games is to witness an epic saga of evolutionary trials and tribulations, sprinkled with occasional humor and calculated risks. He truly proves that in the ecosystem of chess, persistence, adaptation, and a pinch of tactical cunning keep the organism thriving.
Keep an eye on shubhu413 — a player whose chess biology is anything but static.
