Jingjie: Probability Cloud - Nagumo's Dilemma is a Pacific carrier command simulation set against the carrier battles of World War II. "Nagumo" refers to Chuichi Nagumo, the Japanese admiral who commanded the First Air Fleet during the opening Pacific War operations and the Battle of Midway. The game is not a biography or a celebration of any wartime regime; it uses this historical command problem as a frame for uncertainty, delayed reports, deck pressure, and decisions made before the truth is fully known.

You are not piloting aircraft or clicking through a fully revealed map. You are reading contact reports, judging confidence, managing a flight deck, and deciding when an uncertain position is good enough to risk a strike.

Every report has age, error, and consequence. A scout can find a possible enemy carrier, lose the trail, return low on fuel, or feed the command chain with information that is already going stale.

The opponent is built for fair adaptation, not omniscience. It can react to visible exposure, learn pressure patterns from after-action evidence, and test repeated habits without reading hidden player intent.

- Imperfect intelligence instead of an omniscient map.

- Carrier command built around time, deck space, CAP, scouts, and strike windows.

- A fairness-bounded adaptive opponent that acts on its own belief picture, not hidden omniscience.

- Evidence-based tactical wagers with visible causes and consequences.

- Compact scenarios built for replayable command problems.
