2018-10-1315:04:04A.Buchanan P0003736 problems soltxt  update Try to deduce the diagram error, as we do have the intended solutions! a) wRh7 is original, but cannot have escaped from cage by white cross-capture as there are too many captures needed. On the other hand, Black only has to make 4 captures so the cross-capture is ok. b) changing the colour of Sa5 shifts the capture balance: now White can cross-capture but not Black, so White but not Black can castle. Thus the retro-logic works with the diagram as it is, but the forward logic does not. How can we repair the diagram?
