## Features
### NNUE Evaluation:
Version 10.3 uses a (768 -> 1536)x2 -> 1 neural network to evaluate positions, which was trained on 2 billion positions of [an Lc0 dataset](https://drive.google.com/file/d/1RFkQES3DpsiJqsOtUshENtzPfFgUmEff/view) using [Bullet](https://github.com/jw1912/bullet).
Version 10.5 uses a (768x5 -> 1536)x2 -> 8 neural network to evaluate positions, which was trained on ~8 billion positions from a collection of Lc0 datasets using [Bullet](https://github.com/jw1912/bullet).

In addition, this engine can use [Stockfish neural networks](https://tests.stockfishchess.org/nns) created for their [SFNNv6/7/8 architectures](https://github.com/official-stockfish/Stockfish/commit/c1fff71650e2f8bf5a2d63bdc043161cdfe8e460), a diagram of which is available [here](https://raw.githubusercontent.com/official-stockfish/nnue-pytorch/master/docs/img/SFNNv6_architecture_detailed.svg).
For the sake of simplicity, this functionality is only possible on the [the HalfKA-HalfKP branch](../../tree/HalfKA-HalfKP).
