Starving the japanese out of oil

[jmw]

I've been able to beat the AI several times by starving Japan of oil. Basically try to harass Japan when they take the Phillipines and Borneo, then pile everything into Singapore and hold on for dear life. Sent all supply convoys to Singapore also. One time I didn't have enough surface vessels patrolling Singapore and the IJN sunk most of my carriers, but the AI wasn't very aggressive subsequently and I was able to hold Singapore, but had to wait for the Essex carriers to finish Japan off.
