Update default net to nn-26abeed38351.nnue SPSA: https://tests.stockfishchess.org/tests/view/60fba335d8a6b65b2f3a7891 New best values: Half of the changes from the tuning run. Setting: nodestime=300 with 10+0.1 (approximate real TC is 2.5 seconds) The rest is the same as described in #3593 The change from nodestime=600 to 300 was suggested by gekkehenker to prevent time losses for some slow workers SFisGOD@94cd757#commitcomment-53324840 STC: LLR: 2.96 (-2.94,2.94) <-0.50,2.50> Total: 67448 W: 5241 L: 5036 D: 57171 Ptnml(0-2): 151, 4198, 24827, 4391, 157 https://tests.stockfishchess.org/tests/view/60fd50f2d8a6b65b2f3a798e LTC: LLR: 2.93 (-2.94,2.94) <0.50,3.50> Total: 48752 W: 1504 L: 1358 D: 45890 Ptnml(0-2): 13, 1226, 21754, 1368, 15 https://tests.stockfishchess.org/tests/view/60fd7bb2d8a6b65b2f3a79a9 Closes https://github.com/official-stockfish/Stockfish/pull/3630 Bench: 5124774
