Phileas Mathieu: The SandwichOSaumon Story

Some chess players are named after legendary fictional explorers. Some have usernames that translate roughly to "Salmon Sandwich." Phileas Mathieu is both, and somehow that combination perfectly describes an International Master who grinds out wins at 1 a.m. while presumably munching on a baguette-based snack. His blitz record speaks for itself: over 1,300 wins, a peak blitz rating touching the stratosphere, and an endgame frequency north of 80 percent, meaning most of his games last longer than the sandwich line at a Parisian deli.

The Opening Repertoire: Closed Sicilians and Curious Gambits

Phileas is a devoted apostle of the Sicilian Defense: Closed, having played it hundreds of times with a healthy win rate to show for it. But the real plot twist is his love affair with the Amar Gambit, an opening so eccentric that playing it at a high level is essentially a psychological operation. He also scores a startling near-70 percent with the French Defense, and has a curious soft spot for the Scandinavian Defense, where his results border on disrespectful.

His first move, predictably, is e4 almost every single time. If you queue up against him, save yourself the suspense: the pawn is going to e4, and the rook is probably going to deliver a check somewhere around move 20, because rooks are, statistically speaking, his favorite checking piece by a landslide.

Nemesis Watch

Every great player has a rival, and Phileas has a most-played-opponent leaderboard that reads like a soap opera. Against notzachm, he has assembled a frankly absurd record of 79 wins, 6 losses, and 7 draws across 92 meetings, which suggests one of two things: either he knows that opponent's soul, or they simply refuse to learn. His battles with elliotaldersontwitch are far more balanced, while bpm_90 remains the thorn in his salmon, holding a winning record over him.

Other frequent dance partners include thefrenchfighter and db-banana, both of whom have been subjected to the full Mathieu experience more times than they can probably count.

Style and Quirks

  • Average winning game length is over 80 moves. He does not do quick knockouts; he does slow-cooked roasts.
  • His comeback rate sits near 88 percent, meaning that dropping a piece barely registers as an inconvenience.
  • One-sided losses are almost statistically nonexistent for him, which is a polite way of saying he loses with dignity.
  • His longest winning streak ran 14 games. His longest losing streak was 9, which he presumably answered with a sandwich.
  • Statistically, his best hour to play is 1 a.m., which raises questions about his sleep schedule that we will not press further.
  • Saturdays are his strongest day of the week. Weekends are for crushing dreams, apparently.

The Legacy

From a modest blitz rating in mid-2022 to peak ratings flirting with the upper 2900s in blitz and bullet, Phileas Mathieu's trajectory has been anything but a straight line, and that is precisely the charm. A titled master who plays offbeat gambits, refuses to resign early, checks with rooks like it is a personality trait, and logs onto the board at 1 a.m.: chess needs more characters like this. Keep the sandwiches coming, keep the Sicilian Defense: Closed flowing, and long may the e4 pawn march.
