I'm fairly new to anything more than the basics of chess and I'm currently working through Bobby Fischer Teaches Chess. I came across this on page 96 (frame 73) in which he asks whether white can mate in one move. I was convinced the white rook could move to H1 to mate. However his answer was "white cannot mate". Why is this the case?
