# Chess Reasoning Traces (Streaming)

This dataset is uploaded incrementally while it is being generated.

## Columns

- `fen`: FEN string
- `valid_moves`: list of legal moves in UCI
- `reasoning_trace`: natural-language trace text
- `chosen_move`: Stockfish best move in UCI

## Usage

```python
from datasets import load_dataset

ds = load_dataset("amazingvince/chess-traces", split="train")
print(ds[0])

# Or stream while it's growing:
stream = load_dataset("amazingvince/chess-traces", split="train", streaming=True)
print(next(iter(stream)))
```

## Notes

- Data is stored as sharded JSONL files under `data/`.
- New shards are committed periodically; re-run `load_dataset` to pick up new shards.
