Tersee Ferdinand: The Grinding National Master
Tersee Ferdinand, better known on the platform as Firmtrain16, has earned the National Master title through a combination of volume, stubbornness, and sharp tactical instincts. They are at their best in rapid chess, where they have played thousands of games and won over 1,700 times in the recorded sample. What makes the achievement more impressive is the starting point: in July 2023, Tersee's rapid rating was 562. By June 2026, they had surged to a peak rapid rating of 2498 (2026-06-22). The steady upward march is best seen in the chart below.
Relentless Fighting Style
If there is one word to describe Tersee Ferdinand, it is resilient. Their early resignation rate is just 2.76 percent, and they reach an endgame in roughly 74 percent of their games. Even after losing a piece, they win 54.7 percent of the time, a number that frustrates opponents who expect an easy win. Their comeback rate sits at a remarkable 83.92 percent.
Tersee's games are marathons rather than sprints. They average more than 70 moves in both wins and losses, and they usually make their first capture around move 6. They also like to strike first in the attack: they are first to check in nearly 53 percent of games and convert those games at a 62.3 percent clip. This mix of patience and aggression makes them a nightmare to put away.
- White win rate: 58.65 percent
- Black win rate: 53.93 percent
- Longest winning streak: 19 games
- Longest losing streak: 17 games, followed by more wins
Opening Repertoire and Specialties
With the white pieces, Tersee is a devoted 1.e4 player. That single move has led them into fascinating battles across the Sicilian Defense, the French Defense, and the Caro-Kann Defense. Their rapid results are especially strong in the French Defense Exchange Variation, where they win 64.4 percent of games, and in the Caro-Kann, where they have collected 137 wins from 223 rapid games.
As Black, Tersee remains loyal to the same family of openings. They turn the Caro-Kann Defense into a fortress and have a soft spot for the cheerful chaos of the Blackburne Shilling Gambit, where they win over 60 percent of the time. In 2026, their Caro-Kann handling reached new heights, with a 72 percent win rate in those structures. A look at their opening performance chart highlights just how dangerous they are when play stays in familiar territory.
Rivalries and Night Owl Habits
No player builds a record like this without a few familiar rivals. Tersee's most frequent opponent is oleg Remarciuc, who has won 13 of their 18 meetings. Rather than avoid the matchup, Tersee kept coming back, a sign of genuine competitive spirit. Against other regular foes the story flips: they hold a 12 to 5 record against huzar2 and a 6 to 2 mark against yeti87.
Tersee also appears to be a creature of the night. Their best winning hour is 2 a.m., and their strongest day of the week is Saturday, when they win over 61 percent of games. Whether this is a schedule preference or a secret weapon is hard to say, but it adds another layer to the legend of Firmtrain16.
