Some people say, that China and Pearl II are “must do” attacks in J1.
I think that depends on the board situation. Now if the Uk fleet retreated out of sight in UK1, then yes lets kill China and Pearl fleet. Obviously the allies play KGF, so take Pearl heavy, they wont counter it, their ships are bound for Atlantic now. Next turn place 3 trannies in sea zone 45 and threaten Hawaii and West coast and Australia and NZ.
But some times the Uk play really aggressive. The brit DD sink your Kwan-tranny, the brit sub sink your only sub, the brit fighter land on the US carrier, the brits now occupie both Borneo and New Guinea (5 IPC) or FIC (3 IPC) and the brit CV and two trannies block your freedom of movement, making it freekin impossible to do Pearl heavy. In this situation I would prioritize to retake Borneo/NG/FIC and kill as many UK units as possible. If you dont, then Uk will use the high income to crush Germany.
