Meet the Crazy Kid
Constantius Leonardo Pratama, better known online as bocah_gila, is a FIDE Master who lives for speed. His username suggests a wild streak, and his games deliver on that promise. He has spent more than a decade turning bullet chess into a personal laboratory of attacking ideas.
A Bullet Specialist
Constantius has made bullet his home. Starting near 1146 in 2012, he pushed his way past 2400 and later touched a bullet peak of 2701 (2023-06-17). His rating journey is a story of patience, chaos, and recovery.
His opening choices are as lively as his handle. As White, he frequently reaches for the Amar Gambit, and as Black he is comfortable in the deep waters of the Sicilian Defense, especially the Closed and Four Knights variations.
Style and Stamina
Constantius plays with remarkable energy. He has won 19 games in a row, but he has also lost 15 straight, which shows he is willing to keep battling through rough patches. He reaches the endgame in more than 82% of his games and posts a comeback rate near 86%. Losing a piece barely slows him down.
- Bullet win rate: roughly 50.6% against strength-adjusted opposition.
- Best hours: around 13:00, when his win rate approaches 70%.
- Frequent endgames and long fights, even in rapid time controls.
Rivalries
Every great speed chess player needs a great rival, and Constantius has two. He has played 64 games against junglemath, with junglemath holding a narrow edge. Even more intense is his series with Novendra Priasmoro, who has 37 wins in 44 meetings. These battles are a reminder that even a FIDE Master can meet a wall online.
The Whole Picture
Constantius is more than a bullet grinder. His Rapid record is quietly superb, with 29 wins against only 3 losses and 2 draws. Yet the clock always calls him back. Whether he is swindling a rook down or riding a 19 game heater, bocah_gila remains one of the most entertaining competitors on the board.
