Every battle is won before it is ever fought.
Sun Tzu's The Art of War, dealt as a deck of 52 cards. Four cards for each of the thirteen chapters: the principles to use, the warnings to heed, and the ground to read. Study the deck, march the chapters, drill yourself, or bring a real situation to the war room.
Verses are from Lionel Giles' 1910 translation, now in the public domain, with chapter and verse cited on every card. A learning tool, not professional advice. War Room mode sends your text to an AI model to generate the counsel; nothing is stored on this site's server.
Sun Tzu's Art of War. Fifty-two cards. Win before the battle.
Thirteen chapters, marched in order. Open a chapter, learn its four cards, watch the episode if you want the full story. A card counts as taken once you mark it known here or in the Deck.
Ten questions. Name the teaching from the verse, and call the bluff on quotes the internet puts in Sun Tzu's mouth. The general who wins makes many calculations before the battle.
Describe the campaign you are actually in. A negotiation, a rival, a launch, a fight you are not sure you should have. The machine reads it as Sun Tzu would and deals the cards that apply.
A reflection, not orders. Tap a card for the verse and the full story. For anything with real stakes, a qualified human beats a card deck.
