I've noted that this form of play was presented by R. Wayne Schmittberger.

The Emperor King Chess Zillions implementation fails to 'see' the potential mating position stated in previous postings. So it actually needed a re-write.

And I've worked up an implementation which does. Hacked out a sub-routine which specifically looked for those potential defenders. Since this checked for sliders, I only let the engine check for Knights and Pawns with the 'attacked?' command. This greatly improved the performance of the implementation, increasing the Strength level to over 6 at 3 minutes. And this is best because the AI tends to go for the draw by stalemate(Q-c8) if run at Strength 2 or less.

The implementation includes both Emperor- and Amazon-style Mad King games.
