Royal units 1

At the beginning of 2005 I have received an original for Pat a Mat using royal grasshoppers. I was considering introduction m of special pages on CCM dedicated to royal units in general already before. Of course, so far we have already published a few problems featuring them on CCM, you can look them up in our CCM index of fairy elements. Below you can find a selection of various problems with few pieces on the board - 4 or 5.
