Sebastián Terán - The Persistent Pawn Pusher

Meet Sebastián Terán, known in the chess world as SebastinTern, a rapid chess enthusiast who has embarked on a long and winding journey through the 64 squares. From a humble 786 rapid rating in 2019, Sebastián climbed the ranks to reach a peak rapid rating of 1252 in April 2023 — proving that persistence really is the mother of skill!

Chess Journey

Sebastián’s style could be described as a resilient fighter: with a remarkable comeback rate of almost 89%, he's the kind of player who doesn’t give up after losing a piece or two. His endgame is a frequent battlefield — 53% of his games venture that far — often turning into a tug-of-war of strategic mastery.

Despite some setbacks (he's seen both a 12-game winning streak and a 12-game losing streak), Sebastián keeps his cool with a tilt factor of 12, meaning he’s less likely to throw his knight across the room after a tough loss than most.

Opening Repertoire & Performance

A true fan of the classics, Sebastián often dances around the Philidor Defense, playing it in over 800 games with an almost even record, slightly tipping the scale with a 47.57% win rate — not bad when you consider the thousands of pawn structures and sacrifices involved. He also wields the King’s Gambit family with considerable flair, sporting win rates above 53%, especially shining in the King’s Gambit Accepted Fischer Defense with over 57% wins. Clearly, Sebastián likes to keep his opponents on their toes with aggressive, tactical openings that promise fireworks (and sometimes explosions).

Playing Habits & Style

Sebastián prefers to end his battles early sometimes, evidenced by an early resignation rate of 5.39% — perhaps a strategic admission when the king is inevitably cornered. However, when victorious, his games tend to be marathon affairs, averaging around 57 moves per win, indicating his love for complex, drawn-out tactical fights.

When playing White, he boasts a slightly better success rate (52.3%) compared to Black (45.72%), suggesting that he enjoys a bit more initiative when he starts first. Expect him to capitalize on his pawns and bishops and steer the game into positions where his tenacity and tactical awareness shine.

Favorite Battles

Sebastián’s recent games reveal clashes dominated by the Philidor Defense and Queen’s Gambit Accepted lines, showing his comfort with these time-tested battlegrounds. In an epic recent match on June 4, 2025, he claimed victory on time against YOYSSEF27, wielding the Philidor like a maestro conducting a symphony (or perhaps a thunderstorm). However, even the best stumble — he experienced a heartbreaking resignation against natsuken333 the same day, reminding us all that chess is as humbling as it is thrilling.

Overall Record & Fun Facts

• Total Rapid Wins: 3,238
• Total Rapid Losses: 3,223 (talk about close battles!)
• Blitz games? A modest dabble with 1 win and 3 losses, because rapid is where the heart is.
• Longest winning streak: an impressive 12 games — clearly when he’s on fire, it’s blazing hot.

Outside the chessboard, Sebastián might very well be plotting his next pawn storm — or just wondering why his knight always ends up in funny spots. Whatever the case, his love for the game, his resilience, and his strategic mind make him an inspiring player. Whether you face him online or ponder his games, expect determination, tactics, and maybe a cheeky gambit or two.
