Alex,
I see this becoming a BIG JOB for you, I mean seeing that no one repeats the same position twice or repeats a position that someone else has posted. I'm sure I would have trouble doing that, good luck my friend.
Here are a few more.

Drawn GameAlex, you didn't answer my earlier question as to whither or not you are limiting this contest to examples of
"one for one" trades or not.
I think maybe this is a good idea and that maybe later an additinal contest could be done limited to examples of
"two for one" trades and then another contest after that for
"two for two" trades, continuing on in this way.
Well now I have posted 8 trades and you have only posted 6, I think I will go and find someone I can brag to, saying
"I'm beating the World Champion at his own contest". 
LOL.
Regards, "Pal"
