Taking advantage of scenario knowledge

[Scud]

I always inform my opponent if I've played a scenario before. My brother and I started playing back in the late nineties starting with EFII scenarios. We played them in the level order they came up. We're now at level 10 (we'll be here awhile). So when an opponent picks EFII, most likely I've played it. WF, I've probably played half of them and maybe more.

What can you do? If I remember the scenario and I know where reinforcements enter, you bet I'm going to shell it, but it usually isn't that easy. Reinforcement routes are usually pretty far back and out of LOS.

I suppose the fairest way to handle it if the opponent really cares (so far no one has) is to tell them to open the file from both sides and get a look at what the opponent has and where it's coming from. Then play, kind of like a mirrored game. Personally I don't like knowing, but at least the person you're playing wouldn't be able to complain in the end if they lose.
