I don’t think its a bad move, if you are going KJF. I wouldn’t use it if I were going KGF though.
But in the case of a KJF I’d consider it, I probably wouldn’t go strafe though. I’d just stick it out to the end and wait on the trn move. Obviously you lose the option of getting the inf from Aus to Ind rd 1. But if you wait out the battle and it goes well, you’ll still be able to get the inf to India on rd 2 since the south Indian Ocean should be safe and if the battle goes poorly and the J BB (and possibly the AC too) survive you can still move the trn (possibly loaded) to sz 30 and try and bait Japan to either move the BB further out of position or if the AC survived I suppose J could use a ftr, but then the AC is out of position.
I’m not sure if this makes Pearl more or less likely, but if J still does Pearl they should lose their sub and the Cru (if not killed there) will be killed on a US counter. And if Japan foregoes Pearl the US might be able to stack its fleet At Solomon in rd 1 (certainly rd 2 with heavy rd 1 naval buy) and really start to mess with the south Pacific early.
Further if you want to be ultra aggressive and try to overload J with targets you can stack Bury with Russia (possibly bring over a ftr if you did Wrus only) and then follow up with UK buying 3 subs for India.
The subs can be insurance if the BB survives, it won’t want to linger all alone for too long.
You’ll be light on a couple of Indian troops but Japan should not be able to really threaten India much in the early game given the naval threats or possible bait of Russia stacked in Bury.
However, with all this said you could be telegraphing the move if you are all in with Russia, so maybe you lay back with them so you can make sure Germany doesn’t go heavy navy and threaten London or go into tank blitz mode, which would certainly change how you play UK 1 and possible force you to call off the Sz 37 attack.
And quickly back to the sub buy and transports. If you do move the loaded trn to Sz 30 the subs can certainly deter a lone BB from going after it. So you should be able to recoup 2 inf to India on rd 2. Now if J survived with a BB and AC and took out the loaded trn with them or brought in a fighter from SE Asia you could still take a shot, and hope after 2-3 rds of battle you can at least get two and sink the AC. Or finally if you landed your bomber in Per on UK 1, you can now threaten an attack of 3 subs, 1 bomber. Sometimes the threat is just enough.
I’m thinking at this point J probably sees the threats and pulls back to a safer spot like Sz 61 and UK can now focus on ground troops for India and let the US do the rest of the heavy lifting in the Pacific.
It’s an ALL-IN approach to a KJF in rd 1, but it can really work provided you have a real good Russian player and Germany opens with a “standard” opening (no ultra heavy naval buys and certainly no G1 Egy or Trj attack).
