chorcat/rukh-games-elite
Games from the Lichess Elite Database (2500+ against 2300+, no bullet), converted to legal UCI with the same schema as rukh-games-1800. Used for supervised fine-tuning on strong play.
Part of Rukh, a chess language model built from scratch
as a course on generative and agentic AI. Every derived dataset ships with the exact filters and
counts of its manifest.json, so it can be regenerated with rukh data elite.

Preference pairs from the multi-PV Stockfish lines of rukh-positions-eval: the best first move against a legal move at least 100 centipawns worse for the side to move (mates count as 10000). One pair per position, balanced by phase.

chorcat/rukh-puzzles-split
Lichess puzzles with rating deviation <= 100 and at least 100 plays, banded by difficulty (1000-1500, 1500-2000, 2000+) and split into test and train by a seeded hash of the puzzle id, each with the moves of the game it came from, for tactical evaluation and fine-tuning.

A balanced sample of rukh-games-1800: up to n_per_bin games per 100-Elo bin of the average rating of both players, for Elo conditioning experiments.

chorcat/rukh-pairs-onpolicy
Preference pairs built from the moves the model itself proposes. The positions are exactly those of rukh-pairs-dpo, so the only thing that differs between the two datasets is where the two moves came from -- which is what makes a DPO run on each of them a comparison. Four moves sampled per position at temperature 1.0, scored by Stockfish at a fixed depth of 10, keeping the best and the worst when they are at least 100 centipawns apart.
