The Long Climb

July 2014 set the tone: 104 blitz games in the very first month, rating up from 1355 to over 1800. By December 2014, after another 252-game month, the 2000 barrier was gone. Then came the honest, unglamorous years parked between 2000 and 2100, a 2019 surge past 2300, and a slow, stubborn grind from there. The 2025 campaign deserves its own museum wing: months of 800 or 900 blitz games, capped by a career-best 2641 (2025-12-19) in December 2025.

For perspective, the win rate against higher-rated opponents sits around 30%. That is why the climb took twelve years instead of twelve weeks. The ladder was not leapt; it was slowly, cheerfully devoured, one poisoned London at a time.

The Repertoire: Poisoned London and a Pterosaur Colle

With White, the law is simple: a pawn on d4 and a bishop eyeing the horizon. The signature dish is the Poisoned Pawn Variation of the London System, played 1,232 times in blitz alone at a 55% win rate. Around it lives a soft spot for openings with magnificent names: the Nimzo-Larsen Attack (1.b3, pure flair), the Döry Defense, a brief Amazon Attack era, and the Colle System's Rhamphorhynchus Variation, named after a flying reptile, presumably because opponents feel something prehistoric chewing on their position.

With Black, loyalty shifts to the sturdy Caro-Kann Defense, 746 blitz games of it, plus the Pirc Classical, the Alekhine and the occasional Closed Sicilian. The archives also reveal a genuine character arc: 341 first-move e4s in 2014, 2,142 first-move d4s in 2025. People change. Openings mature. The win rate stays suspiciously reliable.

The family blueprint, deployed since 2014:

Style: The Comeback Machine

The statistics describe someone who simply refuses to panic. Endgames appear in 78% of games, and the average win lasts about 77 moves: no cheap tricks, just slow, courteous suffocation. The comeback rate is a monstrous 85%, and even after dropping a whole piece, roughly half the games still flip into wins. The Queen is the favorite checking piece by a landslide, with more than 14,000 royal visits on record.

Then there is the clock: more than 2,500 wins by timeout, because in blitz the flag counts as a piece. And when a position is truly dead, resignation arrives promptly and without drama; a tilt factor of 10 confirms a practically monastic relationship with losing.

Rivals, a Nemesis, and the 8pm Curse

Every long career accumulates recurring characters. Via Lastiningtyas has met anak_kotabumi 63 times and lost 38 of those meetings, yet keeps returning, which is either friendship or an elaborate revenge plot. catur1123 owns the most balanced rivalry on file: 51 games, 25 wins to 26 losses, essentially a human coin flip. And then there is karenfrance, the certified nemesis, ahead 10 to 6 with 5 draws across 21 encounters.

Timing matters too. At 22:00 the win rate climbs to nearly 62%; at 20:00 it collapses to 33%. Tuesdays are the best weekday, Wednesdays the curse. Translation: do not trust this player with a chessboard straight after dinner, and maybe never on a Wednesday.

Quick Facts and Odd Numbers

• Career blitz record: 6,754 wins, 5,551 losses, and only 715 draws. Draws are technically legal, just rarely used.
• Longest winning streak: 18 games. Longest losing streak: a merciful 10.
• Bullet: 1,070 wins, with a peak of 2356 set in a month containing exactly one game. A flex so efficient it should be studied.
• Rapid: only about 100 games, yet the best strength-adjusted win rate of any format at 65%.
• Daily chess: exactly one game, one loss, one Catalan Opening. The experiment was concluded on the spot.
• August 2025: 920 blitz games, roughly 30 a day, every day, all month.

Final Word

Twelve years, 15,000 games, one solitary Catalan, and a name that already promises victory, since "jaya" means glorious in Indonesian. Meet anak_kotabumi at your own risk: ideally at 22:00, ideally on a Tuesday, and ideally not right after they have lost a piece, because that is exactly when the comeback begins.
