The Man Behind the Alias
Jesus Vallejo Diaz, better known online as Chichin_chao, is a FIDE Master with a serious passion for speed. While his official title comes from FIDE, his true kingdom is blitz chess, where he has played more than 1,600 games and collected 858 victories. His preferred time control is blitz, and his relationship with longer formats can best be described as "polite avoidance."
A Decade of Blitz Chaos
If you look at his blitz journey from 2019 through 2026, you will see a chess player who refuses to do anything by halves.
The line goes up, down, sideways, and then up again like a rally car driver navigating a mountain road.At one point Chichin_chao reached 2662 (2026-08-11), which is impressive by any standard. He has a 12-game winning streak on his resume, and also a 7-game losing streak, because balance is important.
Openings and Other Adventures
Jesus is not afraid of unusual positions. He has played the Alekhine Defense with black, the Sicilian Defense with both colors, and a suspicious amount of the Bird Opening with white. The Bird Opening, especially the Dutch Variation, has been very good to him, with a win rate above 60 percent in blitz.
He also loves the Amazon Attack, Siberian Attack as black in bullet, a line that has rewarded him with a 72 percent win rate. His record with the Döry Defense is less kind, but he still plays it, which is either courage or extremely specific taste.
If you want a flavor of his Sicilian world, here is a classic little dance:

Resilience, Tilt, and the 1 AM Club
