First just two comments, to the question itself. Why searching for a reply its received with sarcasm? Why we can't have doubts about the game rules? Second comment, maybe its more apropriate put your question on the Checkers 8x8 Forum instead of this one...

Ok my reply, I think not having 100% sure, (which I would like a normal answer too!) that move its illegal here in BK, and in the "regular" turkish game also (thought theres a lot of official turkish variations, with different rules).

The turkish variation implemented here its not the same as the "regular" Turkish game, but I think its been on the todo list the implementation of the right rules. If not I apologised for my mistake.
