Meet Mistheoretical
David Balogh, better known to the internet as Mistheoretical, is a FIDE Candidate Master who has played enough online chess to fill several theory notebooks. The dataset shows a player who lives across rapid, blitz, bullet, and daily games, with more than 15,000 tracked battles in total. His profile says his true preferred time control is Rapid, and the numbers back it up: in Rapid he has 104 wins, only 11 losses, and 6 draws.
The d4 Factory
Give David the white pieces and the first move comes fast: 1.d4. He has used it so often that it is less an opening choice and more a lifestyle. His main system is the Amazon Attack, especially its sharp cousin the Siberian Attack, which appears in thousands of games. As Black, the French Defense is a reliable anchor, and his rapid results in the French Exchange line are especially clean.
If you want to see where the wins pile up by opening, the chart says it better than any theorem:
.Victory in the Long Game
Numbers can be dry, so here is the fun part. David once won 62 games in a row. His longest losing streak was only 9, which for a player with that many games is a gentle bump in the road. He loves endgames, is comfortable when games go long, and his comeback rate sits in the very fancy neighborhood: over 82%. Even after losing a piece, he finds a way to win more than half the time. That is not theory, that is stubborn excellence.
Rivalry Report
No real chess profile is complete without a worthy rival. For David, the most recurring opponent was luciiddream. They met 173 times, and it was visibly a war: David took 77 wins, luciiddream took 93, and the remaining 3 games were draws. It is an old rivalry, a difficult ledger, and the kind of rivalry that gives a Player a real story to tell.
