There are probably over 1000 names for openings the way you describe-2 or 3 moves. Worthless to me, also (the names, that is), but, these initial moves may dictate the progression of the game. For example, a game started with e4 is usually a faster game than if you start d4.
To see what a formation is named after 6-8 moves, go to the game explorer link here (under "learn") and put the moves in. The site will show the names of the opening or defense.
rookie here,
when i look up openings, i find only 1-3 moves, and it means little to me.
if i'm playing, and neither sides attacks for 6-8 moves, i get to set up my desired formation, far beyond just an opening.
what are these developed formations called, and how can i look up images and names for them?
thx.
