HG says: "if a virgin King is on h1, a black Bishop on h2, and a black Knight on g4, the King can move to h3. If his own Bishop was on h2 instead, he could not. "
>>As Fergus said, in both cases, the Bishop on h2 being black or white, the King cannot jump on h3 because h3 is a square under threat.
For several reasons, I wanted to put in Metamachy the original rule of the old medieval King's leap (although they had no real standards in those times) which preceded the modern castling in chess. This is why I kept the rule that he can jump over a threatened square, although it is a bit weird, I agree.
There is the same relic in modern castling. We don't see it because when we mechanically castle, we first move the King two steps, he is not jumping. But the castling's root was a particular case of the King's jump, where the Rook was coming close to the King and the King jumping over. We still have the rule that the square d1 or f1 shall be not attacked.

Zanzibar follows Metamachy, that's right.
