Ostfront Tourney Fog of War question

[Nikb]

I'm glad this question has popped up.

I think it is fair to interdict with arty if it is a spot that you would normally lob a few rounds into. However, I personally draw the line at lobbing in arty where I know specifically from playing the mirror game where an opponent has hidden units. That to my way of thinking isn't cricket.

What I wouldn't condone is something like having the same scenario open as you play the proper turn. I haven't heard this happening with SB but I do know it has cropped up in other titles.
