Yes, this has been a problem with lots of players, it seems: you win a game, and the game continues anyways. I had one game that took a few minutes to realize i'd won, but did eventually. All we can do is hope Fencer does something about it :-)

It would also make the game incredibly different - in Turkish Checkers, you can't move out your third rank pieces necessarily, because your opponent can likely double jump. With the first rank not empty, you can safely move that piece out because you can jump your opponent back after a single jump. If you wanted to speed up the game, it would make MUCH more sense to make it 6 ranks high, rather than leaving the first and last empty.

lol. No problem :-)

Checkers only move diagonally which explains why you can't capture A7. To capture a piece, you must jump over it to the space beyond it, which is why you can't capture F8 (it is on the edge of the board).
