For a while, anytime I got the chance to play the
Scotch, I would as long as my opponent (being black) played the moves. If they did not follow the move order, I would just continue with something else, but I noticed, the more I play an opening, the better I get at it (This is obvious).
Another way to view this question is, besides 1 or 2 move openings such as the
Pirc, etc which obviously have been defined as being reached after 1 or 2 moves, how can I force my opponent and this may not be possible, it may just be by chance, to play moves up to the point where my opening is defined?
Certain openings I have found this actually works pretty well such as the
Ruy Lopez because it has such a natural move order
1. e4 e5 2. Nf3 Nc6 3. Bb5., but in other openings, it is not so easy.
