The Battle of the Bismarck Sea is a battle in which the United States and Japan participated in naval battles during World War II. In 1943, the Japanese admiral was ordered to move the transport fleet to New Guinea. He had to choose between the rainy northern route and the sunny southern route. Both took 3 days to sail. The U.S. military knew it was going to sail and wanted to pursue it with a bomber, but didn't know which route to take. Therefore, the US military had to launch a reconnaissance plane to reconnaissance of the Japanese convoy, but the reconnaissance plane could only explore one route per sortie. Both the Japanese and the US forces had to make decisions without information about the other's plans. If the Japanese convoy is on the route that the US military has reconnaissed, the US military can send bombers right away. Otherwise, the US military loses one day from the date it can bombard. Even on northern routes in bad weather, the bombing will be impeded (i.e. you lose a day on the date you can bomb). The US military's pay is the number of bombing days, and Japan's pay is minus the number of bombing days. (a) Get a regular game. (b) Check if there is a superior strategy and find the Nash Equilibrium.
