No.324 – Manfred Rittirsch – The problem below uses a combination of two conditions – Anticirce + Superguards – and by the author’s words can’t be tested by computer, as the both programs Popeye and WinChloe doesn’t treat this combination properly. The inventor of Superguards condition, Mr.Seetharaman, acknowledges it as well. (JV)
Superguards: Any piece (including Kings and pawns), which is observed by another piece of the same color cannot be captured. Pinned pieces also observe.
Anti-Circe: After a capture the capturing piece (Ks included) must immediately be removed to its game array square (necessarily vacant, else the capture is illegal). R, B & S go to the square of the same colour as the capture; Ps stay on the file of capture.
