Maximum number of non-pawn pieces on the board notes how to get the maximum number of non-pawn pieces on the board.
But what about the maximum number of points possible? It seems like this starts easily enough. For instance: 1. a4 b6 2. a5 Bb7 3. a6 h5 4. axb7 Nc6 5. b8=Q, with a plan of Ra1-a3-e3 to allow Black's a-pawn to queen.
The basic idea would be to have each side capture the other's 4 minor pieces, so that 1) the capturing pawn becomes passed and 2) it creates an opposing pawn become passed. Once the two pawns above have queened, White or Black could take bxa(1-8), Then cxb(1-8) and so forth.
This is the outline, but how do we create a legal game that satisfies this?
