So here’s where my numbers stand right now on J4 land defense.
I’m basing this on USA collect 17, 17, then 57.
Assuming no Japanese air casualties, Japs bring 18 inf 5 art 1 arm 11 fig 8 tac 2 bmb plus 2 bb 2 cru
Allies defend with 17 inf, 1 art, 1 mech, 9 armor, 8 fig, 1 tac, 1 bmb, 3 aa
I get 87% odds without bombardment. With bb/cru bombardment, Japanese odds increase to 94%
Substituting aas for tanks in the last USA buy only seems to increase Japanese odds, but if one was in this situation it would probably be worth the risk to buy 4 aa instead of 4 armor on USA3, providing for 21 aa shots.
Of course, if USA uses blockers or conducts naval resistance somehow on USA1-2, the Japanese could lose 1-2 planes or more.
Here are some odds with bombardment
minus 1 fighter=89%
minus 2 fighters=81%
minus 3 planes=71%
minus 4 planes=59%
The only silver lining for the game itself is that given how unbalanced Pacific is, it’s questionable whether a Hollywood tactic with as much as 20% to fail is better than a mainland tactic that might offer more favorable odds. Any attrition of Japanese fighters seems to dramatically increase Allied odds of success…AND it is heavily dependent on average AA rolls—this might make a conservative player like me somewhat wary of this strategy.
Of course, in a f2f game the Allies can’t be expected to play perfectly unless they’ve read this entire thread. But not every Japanese player will execute perfectly either.
I suspect a straight bid in this game should be at least 12 anyway–that would be sufficient to try a more ambitious blocker strategy on USA1 where you block all of Hawaii, Alaska, and Aleutians. Or you could just bid 4 inf to WUSA–not terribly strategically useful off the bat but USA would use them to fill transports soon enough.
The defensive challenge for Allies looks to be forcing the Japanese to sacrifice as many planes as possible. My impression is this doesn’t look easy and the Japanese shouldn’t have to sacrifice more then 1 fighter to accomplish their objectives on J2-J3.
Still gotta look into naval strats but there doesn’t seem to be enough time for Allies to accomplish anything via naval consolidation. As early as J2 the Japanese can consolidate into a blob fleet which means they need to be drawn out to suffer losses.
