I thought you should have attacked W India the turn before. I also think you could have lost a bomber in the attack on India but then I would have just been able to retake it.
Anyway, I’m not really sure why I haven’t had more success with this plan. I think I just haven’t sorted out the nuances. The naval base on Iceland allows you to sail around a blocker in SZ124, but two blockers can still stop the advance. You also need to be careful that they can’t sink your fleet in SZ123. Besides those two problems, I think the plan is great!
Happy to play again when you’re up for it.
