I agree that tactics is not only sacrifices. Therefor I base my claim on test
suites of two types:

(1) Tactical test suites such as ECP-GCP and IQ2.
(2) The king attack part of the WM-test.

These are totally different in nature (first for sacrifices, second for
intuition) and Gothmog excels in both.
