Update main network to nn-f68ec79f0fe3.nnue Trained with the following yaml definition https://github.com/Disservin/nettest/blob/8da0a21503adb341bc89ca20b4e2f166c7c9720d/threats.yaml and the following trainer change https://github.com/official-stockfish/nnue-pytorch/commit/d87c248fbed584d08df59820ae0dd309e9b35c85 Initially I saw a lot of weird 0 scores in the binpack, since then @linrock has explained to me/us their meaning and mentioned that they are actually mostly skipped.. except a very small percentage, however it seems this change was still beneficial.
