New default net nn-3b20abec10c1.nnue This net was created by @pleomati, who manually edited with an hex editor 10 values randomly chosen in the LCSFNet10 net (nn-6ad41a9207d0.nnue) to create this one. The LCSFNet10 net was trained by Joost VandeVondele from a dataset combining Stockfish games and Leela games (16x10^9 positions from SF self-play at depth 9, and 6.3x10^9 positions from Leela games, so overall 72% of Stockfish positions and 28% of Leela positions). passed STC 10+0.1: LLR: 2.94 (-2.94,2.94) <-0.50,2.50> Total: 50888 W: 5881 L: 5654 D: 39353 Ptnml(0-2): 281, 4290, 16085, 4497, 291 https://tests.stockfishchess.org/tests/view/60cbfa68457376eb8bcab49a passed LTC 60+0.6: LLR: 2.94 (-2.94,2.94) <0.50,3.50> Total: 25480 W: 1498 L: 1338 D: 22644 Ptnml(0-2): 36, 1155, 10193, 1325, 31 https://tests.stockfishchess.org/tests/view/60cc4af8457376eb8bcab4d4 closes https://github.com/official-stockfish/Stockfish/pull/3564 Bench: 4904930
