                        CHECKMATE
<rooksac.jpg=>
    The object of chinese chess is to reduce the opponent to stasis.
The game is over when the enemy king is cptured, or there is no
legal move. Here the Red General is in dire straits, and Green has
already won the game. The coup-de-grace is administered by a rook
sacrifice.

    The positions show that red is losing, but 'che', the program
finds a rook sacrifice to take checkmate quickly.

     The red general may not take the rook because black has a cannon
behind the king's pawn. The advisor captures the rook.

    Now the game is over.
