Marcos Duarte - The Relentless Combatant of the Chessboard
Known online as MarcosDB, Marcos Duarte is a chess player who approaches the game like a fearless gladiator in the arena—sometimes triumphant, sometimes bruised, but always fiercely committed.
Rating Journey & Style
Marcos’s best rapid rating peaked at a respectable 1091 in early 2021, a milestone achieved after many battles fought on the 64 squares. Although his rapid rating has seen some dips, his fighting spirit remains unbroken.
His bullet and blitz ratings, while modest (max 695 and 456 respectively), show his love for fast, adrenaline-pumping games. In daily chess, he stuck to a solid 800 rating, showing he can hold his ground when given more thinking time.
Opening Repertoire
Marcos’s favorite playground is the King’s Pawn Opening and its many variations, contributing to 151 rapid games alone—worth noting is his notable success with less-cultivated sidelines like the Scandinavian Defense Mieses Kotrc Variation where he boasts an impressive 61.5% win rate. When feeling adventurous, he occasionally ventures into the Alekhine’s Defense, though its 19% success rate might make him think twice next time.
Record & Opponents
With an overall rapid record of 340 wins, 355 losses, and 52 draws, Marcos exemplifies the classic underdog—always in the trenches and never backing down. His longest winning streak was an admirable 8, but beware his 14-game losing streaks; they remind us even heroes have their off days.
He has faced many opponents repeatedly, with mrtonchy appearing 18 times and a mixed success rate against other frequent foes.
Playing Characteristics
Marcos’s games rarely end quickly—his average moves per game hover around 60, whether winning or losing, portraying a patient and resilient style. Early resignations are rare (just 4.4%), proving that giving up is never on his agenda.
His tactical awareness shines with a 69.6% comeback rate, showing that even when the chips are down, Marcos fights back with grit and guile.
Psychological Quirks
Beware the tilt factor! Standing at 14%, Marcos sometimes lets nerves get the better of him but balances that with a remarkable 100% win rate at midnight games—apparently, the witching hour is when the king awakens.
