# avewright/chess-soft-multipv-lichess

Soft MultiPV policy targets for chess transformers (compact move vocab).

Built from Lichess cloud evaluations + local harvests. Each row is a position with
an 8-wide soft move distribution (`soft_indices` / `soft_probs`) plus hard best move.

## Fields
- `board_array` (64): piece encoding
- `turn`, `castling`, `ep_square`
- `move_idx`, `cp`, `mate`
- `soft_indices[8]`, `soft_probs[8]`
- `label_depth`, `phase`, `source`, `cache_name`
