Hi firends,

I would add to the Nicolas' remark that, for all the diagonal CF / PR cases, both "vs"
and "&", the only one showing an example is CF(B) vs PR(B).

Reinforcing the Nicolas question on the PR(R) & CF(R), what about the equivalent
"vs" case?

Best,
Roberto

Hi chess friends, 

To Roberto's list of "challenges of the future", we can add the difficult 
and appealing diagonal type : PR(A) & CF(A). The point is that when CF is 
easy (eg for knights) then PR is complicated, and vice-versa. 

The simplest one is probably when A=Rook, but even in that case this is 
unclear, at least to my eyes, how to construct it. 

Best wishes, 

Nicolas.
