Sergio Markeluk (aka aspaclaria)

FIDE Master & Chess Aficionado

Sergio Markeluk, proudly holding the title of FIDE Master, is a chess player who approaches the 64 squares with a mixture of strategic prowess and a dash of mischievous charm. Known in chess circles as aspaclaria, Sergio’s journey through the ranks is nothing short of a roller coaster—full of ups, downs, and a few unexpected twisty turns on the chessboard.

Starting from modest beginnings with a bullet rating hovering around 1591 back in 2014, Sergio has steadily improved, hitting a blistering peak bullet rating of 2088 and an even loftier blitz peak of 2121. Although sometimes the losses outweigh the wins, Sergio’s resilience is legendary: a comeback rate surpassing 81% means few setbacks are ever permanent. After losing a piece, Sergio still manages to snatch victory nearly 43% of the time—proving that giving up early is just not in their DNA.

Known for a patient endgame style (engaged in nearly 74% of their games), Sergio isn’t just about flashy openings or quick gimmicks. There's a mix of solid openings, such as the Sicilian Defense (where the Mengarini Variation is a personal favorite boasting an 83% win rate in bullet), the Closed Sicilian, and an intriguingly classified "Top Secret" opening that seems to baffle opponents and fans alike. Despite dabbling in some sharp lines, Sergio exhibits a playful yet calculated style, averaging around 60 moves per win—yes, the marathon chess battles are the most fun.

Psychologically, Sergio is as stable as the rook on its corner square, with a tilt factor of just 14 and an unparalleled best time to play being 11 AM (chess and coffee, anyone?). Those who play against Sergio know that the marathon session of patient grinding can outlast many, and with long winning streaks peaking at 16 games, momentum is never underestimated.

Notable Games & Recent Highlights

Recently, Sergio clinched victory against mafopcom in a 120+1 classical time control game, showcasing deep opening knowledge of the English Opening—Symmetrical Fianchetto Rubinstein Variation. This game demonstrated Sergio’s ability to capitalize on minor positional nuances and force the opponent’s resignation in a tense endgame.

On the flip side, even a FIDE Master faces tough opponents; Sergio’s recent losses include battles against sharp tactical players. But win or lose, every game adds to the rich tapestry of experience that makes Sergio aspaclaria a respected and formidable figure in online chess communities.

When not analyzing the board, Sergio can be found enhancing their repertoire, practicing tricky endgame techniques, or just plotting the next sneaky pawn break. Whether in bullet, blitz, or classical, Sergio Markeluk reminds us all that chess is a test of patience, wit, and a good sense of humor when faced with unexpected forks!
