VVLTC search tune This set of parameters was derived from 3 tuning attempts: https://tests.stockfishchess.org/tests/view/65d19ab61d8e83c78bfd8436 (80+0.8 x8, ~40k games) Then tuned with one of linrock's early L1-3072 nets: https://tests.stockfishchess.org/tests/view/65def7b04b19edc854ebdec8 (VVLTC, ~36k games) Starting from the result of this tuning, the parameters were then tuned with the current master net: https://tests.stockfishchess.org/tests/view/65f11c420ec64f0526c46fc4 (VVLTC, ~45k games) Additionally, at the start of the third tuning phase, 2 parameters were manually changed: Notably, the triple extension margin was decreased from 78 to 22. This idea was given by Vizvezdenec: https://tests.stockfishchess.org/tests/view/65f0a2360ec64f0526c46752. The PvNode extension margin was also adjusted from 50 to 40. This tune also differs from previous tuning attempts by tuning the evaluation thresholds for smallnet and psqt-only. The former was increased through the tuning, and this is hypothesized to scale better at VVLTC, although there is not much evidence of it.
