Step 1: Find nearest teammate, stay behind him equal to the difference in minimum surface detection so that he will always be detected first and shot at before you
Step 2: Head toward the flanks and away from islands as much as possible
Step 3: Find target of opportunity, fire and wait for reaction
If he turns turrets and reacts, you stop shooting and go dark wasting his entire effort
If he doesn't react toward you, free farm
USN cruisers are lone wolfs as they can hunt down ships 1 by 1 from the flanks, stay in open water as much as possible and use your teammates as disposable decoys.
