The I-Boat Raid and CPO Withdrawal adjustments are in play.
USN Endgame Report: I have defeated Larry Meyers on Board 1 of the KOTH Ladder. He resigned after 6 Turns, at which point I was -10 POC. As the IJN, Larry tried to put maximum pressure on me by going for both HI and USM on Turn 3, and I was able to hold HI. It was an uphill struggle for him from that point forward, especially since I had protected most of my key bases. He did convert Samoa, but was unable to hold onto it.
On Turn 5 I made the mistake of slightly under-protecting HI, and he responded with a good move by trying to control HI again. I avoided that, but lost most of my BBs in the process. Turn 6 was decisive as my suicide carrier stopped his SNLF in SPO, allowing my 3 LBA in Indo to hold the area.
