# Self-play refresh, round 1
**Observed match:** 12/32 points, W/D/L 9–6–17, against Stockfish set to Elo 2000.
**Evaluation block:** Initial opening block (openings 0–15).
**Descriptive logistic estimate:** ~1911 Elo; this small match is not a precise rating.
## Method
Fine-tuned after one self-play data-refresh round, mixing student-reached positions labeled by Stockfish with original training examples.
## Interpretation
Released reference scored 15/32 in this block. This result is not directly comparable with the later-block evaluations.
This checkpoint uses the ChessLFM chess-specific tokenizer. For legal move masking, board prompt construction, and search, see the project implementation at https://github.com/0xrushi/ChessLFM.
## Model lineage
Direct starting checkpoint: [mlabonne/LFM2.5-230M-Chess](https://huggingface.co/mlabonne/LFM2.5-230M-Chess). That upstream checkpoint was itself built from [LiquidAI/LFM2.5-230M-Base](https://huggingface.co/LiquidAI/LFM2.5-230M-Base). This experiment therefore descends from LiquidAI's pretrained base through ChessLFM; it did not start directly from the LiquidAI base weights or from random initialization.
