The question is not only about big king safety scores but also about knowledge when to do them big and when to do them small. I do not know if you have the same knowledge about king safety as rebel. If you have more knowledge about king safety in the evaluation then it is more safe to eval trading a piece for 2-3 pawns because the evaluation is less often wrong. Uri
