Superior Development
The Numerical Lead

Point Count Chess, NO. 124, p177
Anderssen v. Kieseritzky, 1851

The Numerical Lead is all about assessing the "number of Pieces" * that have been moved (developed) off their game-starting squares.

The Pieces don't necessarily have to be developed off their Back Rank (the row on which the Pieces start the game); the important bit is that they're developed into positions where they can support the forward development of their army, as a collective unit.

* we don't include the Pawns in this analysis

I'll exclude the movement of the Kings in this analysis, since in practice it's best for the Kings to remain tucked away for the majority of the battle, ideally Castled to relative safety, until the Endgame Phase, when they (should) be mobilized to play an active role in helping to win the game.

Looking at the sequence of moves leading up to Postion #1 (16.Nb1-c3), it's immediately obvious that White has the Superior Development, based on "The Numerical Lead", with 6x Pieces having been developed off their Back Rank, versus just 1x Piece from Black's army ...

(of the Pieces),
After: 16.Nc3
The image (left) shows White has five Pieces that have been developed. The sixth Piece, (King Bishop), has been sacrificed to take-out Black's b-Pawn and drag Black's c-Pawn out of position, away from White's d3-Pawn, in that Chain formation (c2,d3,e4).

Black actually developed 2x Pieces during this sequence, but his King Knight ended up returning to its game-starting square (g8), effectively "un-developing" that Knight (red square), while wasting all that potential to develop other Pieces. So, Black has really only developed his Queen.

King Rook 11.Rg1 Not Developed

* There is an argument that White's Rook "has been developed without moving", as it has clear sight of its King; it can come across to help out on the Kingside; and it can also stay exactly where it is, either to support the a-Pawn, or to be in position to take advantage of the potential Half-Open File (a-file), should White seek to trade a-Pawn for Black's b-Pawn.

By comparison, Black's Queen Rook is trapped in it's corner; it doesn't have any choice but to remain there, and that's why I'd say you could argue it hasn't been "developed without moving", like White's Queen Rook, just mentioned.

For the sake of clarity, for now I'm just going to keep it that only Pieces that have been physically moved, are to be included in the "Numerical Lead" assessment.

It's clear to see that, Black focuses on moving just two Pieces, throughout the entire sequence; by comparison, White's Pieces are developed more as a collective unit; he engages more of his Pieces, developing them into positions that support his building attack toward Black's King.

Development combined with Coordination of Pawns & Pieces.
It's important to note that White's Pieces have been developed with coordination,
in mind ...

They support the other Pawns and Pieces that have been developed toward Black's territory; they haven't just been developed for the sake of moving more Pieces off their game-starting squares, than the opposing army.

With such a commanding Numerical Lead, White was able to sacrifice multiple Pieces, en route to winning this game.

Here's the list of Pieces White allows to be sacrificed, after having built up that lead in Development:

  1. King Rook (Rg1, after 18...Bxg1);
  2. Queen Rook (Ra1, after 19...Qxa1+);
  3. Queen (Qf6, after 22...Nxf6)
