When my friends and I play India always turtles on the Burma Road and in their capitol, the only time to break through is in the beginning before they’ve amassed a huge stack of infantry. That’s why I suggested turn three–one turn to consolidate the navy and build transports around Japan, another turn to move three spaces towards India, and entering their sea zone on turn three. After the third turn war is declared automatically, so hitting one of the Allies with a huge attack on turn three is about the best thing to do–they haven’t had a lot of time to build up and it doesn’t bring the US in any sooner than it would otherwise.
Plus, going for India will prevent them from liberating China later, which has always proven a problem for me. Mid-game, the US is pressuring Japan on the sea, and India is coming up through the Burma Road with infantry and artillery. The way I see it, it’s better to get one out of the way quickly so I only have to deal with one of them later.
The problem is, this strategy leaves Japan wide open for about a turn. If the American navy is anywhere near Japan in that time, I’m screwed.
