Meet George Stoleriu
George Stoleriu, known online as stoleriu, is a FIDE Master who treats the chess server like a 24-hour gym. His preferred time control is blitz, but he spends plenty of time in bullet, where his peak rating of 2999 (2026-05-24) proves he can think at the speed of a hummingbird with a caffeine habit. His blitz peak of 2900 (2026-05-31) is nothing to sneeze at either, though he would probably prefer you call it a "personal best" rather than a rating.
The long climb
From his early days as a 1300-ish daily player to the dizzying heights of online bullet, Stoleriu has spent more than a decade grinding ratings, collecting rematches, and refining his unconventional repertoire. The chart below shows his blitz journey from 2012 through 2026, and yes, it goes up.
The opening laboratory
Stoleriu's opening choices are both practical and stubborn. As White he loves the Nimzo-Larsen Attack, playing 1.b3 more often than most people play their favorite song on repeat. Against 1.e4 he regularly reaches for the French Defense, with especially good results in the Exchange Variation. He also has a soft spot for the Sicilian Defense: Closed, the Döry Defense, and a number of offbeat systems that make opponents spend their clock time wondering what hit them.
His win rate by opening is a museum of informed stubbornness. He wins more than he loses in many of his pet lines, and even when the opening looks unusual, the follow-up is usually sharp.
Rivalries and marathons
If there were a trophy for "most games against the same username," Stoleriu would have a crowded shelf. His most played opponent is SintMaartenCB, against whom he has crossed swords over 200 times and won nearly three quarters of those meetings. He also has lengthy feuds with Demolatorul99, Adham Fawzy, and Vladescu Alin-Cristian. These rivalries are not just numbers; they are proof that online chess can build bonds, or at least a very specific kind of mutual respect.
Resilience and chaos
Stoleriu's numbers tell a story of someone who never quietly goes away. He has an 80% comeback rate, wins almost half his games after losing a piece, and almost never loses a one-sided game. His longest winning streak hit 51 games, which is impressive. His longest losing streak hit 39, which is a different kind of impressive. His tilt factor sits at 39, meaning he is generally steady but has been known to press the "rematch" button with anger in his heart. His best time of day to play is 4 a.m., which explains a lot about his opening prep and his sleep schedule.
