Cross The Sea Under Camouflage
The perception of perfect preparation leads to relaxed vigilance. The sight of common occurrences leads to slackened suspicion. Therefore secret machinations are better concealed in the open than in the dark, and extreme public exposure often contains extreme secrecy.
In Go terms, concealment is possible even though the game is entirely open. One can misdirect the opponent by the way one plays; there may be a latent as well as an overt interpretation of anything happening on the goban.
The Ma book talks about Crossing the sea by treachery. The application to Go would be make extraordinary moves appear to be ordinary moves.
