1. Rcc7 {The threat is 2.Nc3 mate. Black can defend this by moving his knight,
so as to free the d4-square for his king. However, as we see, every one of the
knight's eight possible moves has a fatal drawback:} Nc2 {interferes with line
of Bd1} (1... Nxb3 {self-pins the N} 2. Qd3#) (1... Nb5 {interferes with line
of Ra5} 2. Rc5#) (1... Nc6 {self-blocks king flight on c6} 2. Rcd7#) (1... Ne6
{self-blocks king flight on e6} 2. Red7#) (1... Nf5 {interferes with line of
Rh5} 2. Re5#) (1... Nf3 {interferes with line of Qh1} 2. Qe4#) (1... Ne2 {
interferes with line of Be2} 2. Qxh5#) 2. b4# *
