Overview
Mauricio Ramirez, better known on the board as CMmauricio, is a FIDE Master who treats online bullet chess like a competitive sport, a science, and occasionally a roller coaster. With a peak bullet rating that has crossed the 3100 mark, he operates in a world where mice clicks are faster than deep calculation and the clock is always the real opponent.
Playing Style
Ramirez is not afraid to embrace the unconventional. His most played weapons include the Amazon Attack and the French Defense, sometimes in the same week. He reaches the endgame in roughly 77 percent of his games and averages about 78 moves per win, which suggests he is equally happy outplaying opponents in a marathon or blowing them off the board in a sprint.
His resilience is remarkable. He has won 43 games in a row and also survived a 21 game losing streak, which is the kind of emotional range only a true bullet specialist can appreciate. When he falls behind, he still wins about 85 percent of those games, making him a nightmare to close out.
Favorite Territory
Ramirez plays his best chess in the late afternoon, with his highest win rate around 17:00. As White he scores just under 53 percent, while as Black he remains dangerous at nearly 50 percent. He delivers checks early and often, and his first capture typically arrives by move eight, meaning he is looking for contact immediately.
