Tricky test case (even can't find its analogue). It contains such placement of draughts that you should precisely touch one or several other draughts by your move, and almost identical angles (+/- 1e-8 radians) will not give correct answer. When allow precisely touch got AC.

P.S.
Seems like one enemy draught you touch on the left side and other one - on the right side simultaneously.
