sniper can't shoot 3 spaces

[Ja Karta]

Yeah, line of sight was a bit confusing to me at first.
If a direct line between sniper and target goes through the center of a blocked square then it is blocked.
If a direct line just clips a blocked square then it is not blocked.

It makes sense after seeing it a couple times.
But when I was still in clever I always made a pass and play game to check what would happen if I moved my sniper into a position near a column. It was confusing.
