From 521 to 2839: A Career in Overdrive
Bojun (Bryan) Yang, known online as BYB1112345, did not start as a Candidate Master. In April 2023 his Bullet rating was 521 and his Blitz rating hovered near 1473, ordinary numbers for an enthusiastic newcomer. Three years later he had climbed to a Bullet peak of 2839 (2026-06-14), a Blitz peak of 2722, and a Rapid peak of 2604, a transformation that speaks to relentless studying and an unusual capacity for growth.
The Blitz chart captures the arc perfectly: slow and steady gains in 2023, a strong breakout in late 2024, and a sustained push into elite territory through 2025 and 2026. Along the way, Yang produced a 27-game winning streak and survived an 11-game losing streak, proving that even future Candidates can have rough weeks.
Style, Openings, and a Love for the Endgame
Yang refuses to be boring. His repertoire leans heavily on offbeat weapons such as the Amar Gambit, the Australian Defense, and the Amazon Attack, yet he is equally at home in classical battlegrounds like the Caro-Kann Defense and the Sicilian Defense.
The underlying numbers paint a picture of a fighter who thrives on chaos. He wins 83.78% of games after falling behind, wins 51.52% of games even after losing a piece, and reaches the endgame in 77.41% of his games, where his patience usually tells. His wins average over 78 moves, a sign that he never shortcuts the hard part of chess.
A quick sketch of his kind of opening adventure:
Few players would open a serious game with 1.Nh3. Yang would, and then he would probably win the ending.
A Rivalry for the Ages
No profile of Yang is complete without mentioning his most frequent rival, rayden_tiong. The two have collided 232 times, with Yang winning 166 of those encounters. The head-to-head record includes 9 draws, but the real story is the constant pressure both players put on each other across hundreds of games. Other regular opponents such as edwinchoi111 and ichi1ni2san3 have also felt his wrath, but rayden_tiong remains the measuring stick.
Daily Brain, Bullet Heart
Yang's preferred time control is Daily chess, and the data backs that up: his strength-adjusted win rate in Daily games is a monstrous 74.43%. At the other extreme, he has played thousands of Bullet games and still maintains a strength-adjusted win rate above 50%, proof that his instincts work even at lightning speed. His best results arrive on Fridays, and he is scary at 15:00, when his win rate touches 100%.
His resilience stats are just as impressive. The early resignation rate is only 1.51%, the one-sided loss rate is just 2.76%, and he crushes lower-rated opposition with a 68.42% win rate. Add it all together and you get a Candidate Master who punishes mistakes, outlasts threats, and never stops pushing.
