Enep, that's right! I'm very sorry.

The huygens will add more trouble if anyone wants to make a chess engine that uses it. For one thing, the list of all prime numbers is hard to describe (they aren't even all known). But if played in a normal game, it should not be hard to use as long as it doesn't move far.

The largest known prime number is [2^(74,207,281) − 1] which has 22,338,618 digits. If anyone wants to move a hugens farther than that, first they will have to prove the number is prime. I won't wait for any player who wants to make such a move!:)

For Enep, I'll remember "Enhanced knight - extra pawn"!
