Congratulation,

You have set a new record to beat.

I have experienced the same problem. The AI is not aggresive enough about the protection of its sea lane. Though in one early game it did try to take tarrawa to isolate Espiritu Santo, but it never tried to take Espiritu Santo which result in a a victory as even an isolated base will count.

I don't know how to realy improve the AI. The game is quite complexe to analyze in term of game theory.
