120000 @ 30+0.3 th 1 After my failed series about weighting with king file occupation i try a more general approach by extending shelterWeakness and stormDanger by an extra dimension notKingFile vs kingFile. Because of tc dependency of king safety i tune at intermediate tc 30+0.3 (176 parameters, ck=10, Low throughput).
