It’s not exactly related to any strafe, but a move I sometimes enjoy is to hit sz61 and sink the destroyer there, then send your Aussie sub to sz37 and dive immediately (no combat). This can be annoying for Japan, especially if you put your bomber in range, and kept your fighters at the ready for a UK2 attack.
It’s not as painful as trying to kill a Japanese carrier in the first round, and it gives you some naval flexibility against the IJN in the second round, without requiring you to risk the destruction your own navy in the process. If no good attacks vs Japan present themselves, then your sub can bounce towards Suez and just hang out there until more British aircraft arrive to make it effective.
If the Japanese destroyer in sz61 is sunk on UK1, there is no way for Japan to attack this sub, so it’s safe camped out in sz37 by the Japanese battleship/carrier group (going anywhere the Japanese can go) at least until J2, when it can either attack a target of opportunity or withdraw towards Africa.
I’m very wary of an opening move that leaves the second Japanese transport alive, because it allows Japan to bring their ground units into the fray much sooner. Not attacking sz61 would seem to be a requirement of the sz37 attack, whether you’re going all out or just trying some kind of strafe move. A British bid can change my outlook, another sub or destroyer or fighter bid to UK can make the sz37 trade much better, but OOB it still seems real dicey to me.
