Red to move — checkmate in 12, machine-verified. This is a long siege, not a lightning strike: Red has the larger force — two chariots, two knights, a full advisor–elephant set — but no cannon; Black has a cannon, two knights and a chariot, and a king with room to slip away. Twelve moves, each tightening the net a little more — exactly the strategy carried in the position's name.
The position is preserved in Thích Tình Nhã Thú (game 46). 'Viễn giao cận công' — befriend the distant, attack the near — was the maxim of Phạm Thư, a man beaten half to death on a false charge of treason, who fled into enemy country under a borrowed name and rose to become Qin's chancellor. His full saying and his road there are told in the anecdote below. On this board: do you have the patience to 'swallow it inch by inch' through all 12 moves?
