OAM Chess Lab
OAM Leaderboard

Living leaderboard, populated by qualifying games

The public product loop is: analyse a game → find the Moment → qualify → players enter OAM Live. Player identity is derived from the PGN. No self-registration, no whitelist, no admission gate. OAM100 is a separate frozen historical reference and is shown below.

What is OAM Rating?

OAM Rating measures competitive alignment at OAM Moments. Closer to 0.0000 = closer competitive alignment. More negative values indicate greater measured deviation from the competitive reference.

OAM Rating and Elo ask different questions
Elo asks
How strong is this player's chess performance relative to other rated players?
OAM Rating asks
How closely did this player align with the competitive reference at the moments where OAM detected that the game changed?

OAM Live · Living leaderboard

Beta

A living leaderboard built from qualifying OAM game observations. Currently in testing as the live population grows. Player identity comes from the PGN. Both PGN-derived players — White and Black — contribute independently from a qualifying game. Ties share the same position label.

OAM Live is waiting for its first qualifying games

Bring a PGN in Game, identify the Moment where the game changed, and the PGN's White and Black players are the ones who enter the living leaderboard — never the analyst.
