Hello Dan, First, thank you for taking the time to do the Zillions implementation. I'll start with your first question: 'It seems to me that if the second King can be checkmated, it can never be captured. Are there circumstances in which the remaining King can be captured?' If a single king is checkmated, it means that there is no legal move to take it out of check, however 'The king is the standard chess king, with the exception that it may be moved into check, and it may be captured.' It's ok for the checkmated player to make another move that will leave the king in check, and then the king will be captured on the next turn. At first it might not seem to make sense to allow a king to move into check, and if you have just one left, it doesn't. Even if you have both of them it's still not a great move, unless it happens to be a winning move - a move that checkmates the other player. With two kings vs. one, the situation could arise. So capturing one king and checkmating the other is really the same as capturing both kings, checkmating the second just means the second capture is inevitable. If it's easy to code this, fine, if not, then that's fine too, because it amounts to the same thing. As for the third win condition, I haven't done any Zillions programming, although I've read the manual and some code. Without seeing the code it's difficult to answer. Perhaps the best answer I can give is that I prefer people to playtest the game as it was submitted, but if you think it would impact the AI, you can implement it one way, and then add the other implementation as a variant. Then even if the AI in the 'official' version is weakened, people can still playtest that version playing one another on-line.
