Henrik Juel: Sd6 is paralyzed by Pc5, just like Tb1 is paralyzed by Le4; it does not matter who has the move (2015-07-31)
A.Buchanan: Isn't that wrong though? When Black has the move it is impossible for even neutral pawns to move up the board. One might as well say that in the starting position, nBb2 is checking wKa3! (2015-07-31)
Henrik Juel: The way I think about it is like this
In the starting position, is Ka3 threatened by Pb2? No, because even with Black to move, the only possible pawn move would be b2-b1
In the final position, is Sd6 threatened by Pc5? Yes, because if White had the move, c5xSd6 would be possible. Another way: Suppose Sd6 was black; in that case it would surely be threatened/observed by neutral Pc5, even if Black had the move (2015-07-31)
