Who Is PapaieDudu?
Eduardo Barbosa Mesquita, known across the virtual board as PapaieDudu, is a National Master who treats online chess like a full contact sport. He has played more than 20,000 rated games, with Blitz as his true competitive home. His rating story is one of relentless climbing, and his 2538 (2026-07-06) of 2538 proves that persistence pays off, one game at a time.
The Long Climb
PapaieDudu started his Blitz journey in late 2019 in the 1200s and kept pushing until he reached the 2500s. Along the way he once rattled off 72 consecutive wins, and even a 20 game losing streak could not break his spirit. His comeback rate sits at an absurd 84 percent, so opponents should never celebrate too early.
Signature Openings
PapaieDudu has a deep and sometimes chaotic opening repertoire. He has played the Sicilian Defense more than 700 times in Blitz, often diving into the sharp Najdorf Variation. He also has a soft spot for the Caro-Kann Defense and the Scandinavian Defense, and he is not afraid to reach for the King's Gambit when the mood strikes.
His numbers reveal a player who feasts on lower rated opponents, winning 73 percent of those games, while still holding his own against tougher competition.
Rivalries
No biography of PapaieDudu would be complete without his rivals. His favorite on board sparring partner is Raul Mesquita, who faced him 173 times and lost 155 of those battles. The reverse dynamic applies to yeahboiyyyy, the rare opponent who holds a winning record against him. And then there is whtghost, who managed only 2 wins in 97 attempts. If you get paired against PapaieDudu, good luck.
Quirks and Habits
- He plays best at 10:00 AM, with a 56 percent win rate at that hour.
- Thursday is his lucky day, while Saturday is apparently a trap.
- His white pieces win slightly more often than his black pieces.
- He delivers most of his checks with the queen, which is both stylish and menacing.
- He almost never resigns early, so the game is never over until the king falls.
