Perhaps a series of books. 1.e4 for 1000's then for 1300s then 1600s then 1900's.
1.e4 opening for 1000's then a middle game based on 1.e4, fol ...[text shortened]... s of books that grow as they grow.
This is way beyond my ability to write but liked the idea.
Very good idea! Though chess authors do this in a few selected areas, there's been no real organization to it, and large gaps remain in the areas of tactics, endgames, openings, traps for different levels of playing strength. It's always been frustrating to me that informants and other publications will follow a line of play for 5 - 10 moves, then give the advantage sign to one side without explaining WHY they have an advantage. Perhaps your idea with help to correct this.
