Mauricio Arias Santana - International Master Extraordinaire

Known online as MauricioAriasCR, Mauricio Arias Santana is an International Master who has made the chessboard his personal playground. Sporting a rapid rating of 2000 in 2025 and a blitz peak soaring above 2500 in 2022, Mauricio's fingerprints are all over the fast-paced realms of blitz and bullet chess.

Mauricio's career is a thrilling rollercoaster of highs and lows, perfectly balanced like a well-planned endgame. With a longest winning streak of 10 games, he clearly knows how to ride momentum—though his current streak rests at a modest zero, because hey, even IMs need a coffee break.

Style & Strategy

With an impressive endgame frequency of over 83%, Mauricio is a master navigator in the final phases of the battle. He tends to keep games long and meaningful, averaging 72 moves per win and almost 80 moves for losses—proving he's in it for the long haul. Quick resignations? Hardly. His early resignation rate is under 1%, so he fights to the bitter end.

Mauricio also boasts a tactical comeback rate nearing 90% and an astonishing 100% win rate after losing a piece, which means never count him out—he thrives on turning adversity into victory.

Rating & Performance

  • Blitz: Climbed from 1746 in 2014 to a blistering 2524 in 2022.
  • Bullet: A peak rating of 2462 in 2020, a true test of lightning-fast reflexes.
  • Rapid: Holding steady at 2000 in 2025, with a solid 50% win rate in his signature "Top Secret" opening.

Personality & Fun Facts

Mauricio's tilt factor is remarkably low at 8, suggesting he’s cooler than a bishop lounging on a8. Interestingly, his win rate spikes dramatically around midnight and in the wee hours—perhaps his secret weapon is nocturnal brilliance or caffeine-fueled genius.

His opponents’ win rates vary wildly—from perfect 100% wins against 'chess_hide' to tougher struggles with 'jacosta7' at only 20%. Mauricio keeps everyone on their toes, never revealing all his secrets at once.

In short, Mauricio Arias Santana is a chess force to be reckoned with: patient, tactical, and always ready for the next duel, with a sly smile waiting after every well-played move.
