I am still not happy that I know the rules for which shots can go where. I think I've understood and then my brain fails. I have done a picture to try to clarify my question.
The Red arrows denote attacks from the ISD against three different zones on the AF.
The shot at the rear of the AF crosses the line marking a different zone. The line 'blocks' the yellow spots from 'seeing' each other.
The shot at the front of the AF doesn't cross the line but it crosses where the line would be if it were extended outwards. But the yellow spots can still 'see' each other.
Are all the red shots legit?
