Revert "Further increase safe checks bonus" This reverts commit 4bc2374450e30101392 for two reasons. First regression testing shows almost equal score: Before the patch: ELO: 49.75 +-2.5 (95%) LOS: 100.0% Total: 27205 W: 7113 L: 3244 D: 16848 After the patch: ELO: 48.87 +-2.9 (95%) LOS: 100.0% Total: 20860 W: 5478 L: 2563 D: 12819 Second, and more sensible to me, this patch increases safe check bonuses to 4 times their original value (!) and considering: - Values were already well tuned - Values are highly critical - King safety is highly critical, very TC dependent and very difficult to test - Our testing coverage is partial (self-testing, blitz times) I think is better to be safe than sorry and so I revert the patch. bench: 8440524
