We have good rules here - simple and short. But in this case, unfortunately, they can be misinterpreted.
I have found a systematic bug in Russian Checkers (bugs 1582, 1898, 2001 and 2014).
In our rules there is written: "Unlike International Checkers, it is not mandatory to make the longest possible jump."
It is right, but there is not written an important nuance.
In GoldToken Russian Checkers rules we can read, how King (or Queen) must jump:
"If there is more than one unoccupied square beyond the jumped piece, the king must land on a square from which it is possible to continue jumping, if such a square exists in the chosen direction."
The same it is in Ludoteka Russian Checkers rules , in rules of gambler.ru - the greatest Russian gamesite - and in all Checkers textbooks, published in Russia and previous USSR.
In the situation Russian Checkers (Priidik vs. Edem das Seine) it was necessary to capture 37. ... g1xd4xf6 (or g7) but our program allowed to capture g1xa7.
Then I wrote in BrainKing.ru http://brainking.com/en/Board?bc=110&plla=1041732 , but after that Edem das Seine made 2nd illegale capture 38. ... a7xg1, it was necessary 38. ... a7xd4xf6 (or g7).
Many people believe here that if the BrainKing program allows such capture then it is correct.
What do you think? Is it necessary to follow official Russian Checkers rules or not?
