Sascha,
 
No, it is not ridiculous - but it is solvable.
Each pair of observations must have an unique id, 
and if your data are as regular as claimed, 
you can create the id by:
   generate id=int((_n+1.1)/2)

Adding 1.1 instead of 1 makes sure that rounding
errors don't mess things up. It goes like this:
 
   clear
   input group var strategy
   1 11 0
   1 12 1
   1 13 0
   1 14 1
   2 15 0
   2 16 1
   end
   generate id=int((_n+1.1)/2)
   reshape wide var , i(id group) j(strategy)
   list

Isn't that what you wanted?
 
Svend
