You bump off their orca (is it theirs?) in a stabber, tornado or machariel, they rely on it, so you just move it off the field. bumping the orbitting ships can be frustrating, but missing the orca is much harder.
Or, alternatively: You outmine the rocks they mine. I’m not willing to sub for this, but if you can get three or four max yield covetors and an orca there, properly paying attention, you can literally steal money from under his nose, which will piss him off soon enough.
When he then switches to max yield ships, you call the gank squad.
It’s perfectly doable to mine safely in max yield covetors with an orca. higgs rigs, shield links, webs. spiderweb the whole fleet, move towards celestials for fleetwarps while passing the rock.
