Dusean Mandick

Dusean Mandick (aka ks12190)

Meet Dusean Mandick, a chess player whose rapid rating has been riding a rollercoaster worthy of a Grand Prix track. With a peak rapid rating of 574 in April 2025, Dusean climbed high but also knows what it’s like to slide down to 148 before bouncing back with a fighting spirit.

Known affectionately on the digital chess battleground as ks12190, Dusean fights his battles mainly in rapid and blitz formats, accumulating nearly 220 rapid wins over his career and showing an admirable resilience. His comeback rate is an impressive 65%, proving that even if you knock him down, he’ll be plotting your checkmate while dusting off his pieces.

Dusean’s style is an intriguing mix: he tends to finish his games with an average of around 53 moves when winning, showing patience and strategic depth. However, losses can stretch beyond 56 moves, hinting at a stubborn streak that refuses to quit early. True to the name of a chess detective, he frequently crosses swords with the Kings Pawn Opening variations, where he maintains a solid 50-52% win rate – a battlefield where he’s both noble knight and crafty tactician.

His opening repertoire is a curious blend, dabbling from the aggressive French Defense (which he wins more than half the time) to the less generous Sicilian Defense, where his win rate dips but his fighting spirit never falters. Expect surprises when he’s on the board: he’s equally happy striking promptly at 13:00, his “best time of day,” as he is grinding out those long, twisty fights.

Dusean has the temperament of a chess boxer with a tilt factor of 6 – calm enough to avoid throwing the board, but fiery enough to keep opponents guessing. Whether battling under the clock or plotting a quiet squeeze on his opponents, he embraces every challenge head-on, although he admits to an early resignation rate of about 6.5%, so don't be surprised if he knows when to fold 'em.

Among his most memorable moments? Delivering a classy victory against opponents like silly-gang and adbaaww12a, where his cunning led to resignation and even time wins. On rare occasions, he's been on the receiving end of sharper tactics, such as a game lost by checkmate, but that only builds the legend.

Beyond numbers and moves, Dusean is that player who makes you question if chess is just a game or an epic saga of strategy, nerve, and a dash of humor. If you ever meet him on the board, beware: his seemingly modest rating masks a dogged competitor who refuses to let the pieces rest until the last move is made.

“Life may be unpredictable, but on the chessboard, every move tells a story... and Dusean’s story is far from over.”
