The Advanced Chain
The Chain on Q5 (1 of 2)

Point Count Chess, NO.20, p38
Rubinstein v. Salwe, 1907

This example is similar to No.19, in that White gains his Advanced Chain in a King's Gambit Declined (1.e2-e4 e7-e5 2.f2-f4 Bf8-c5). However, instead of the f-Pawn getting pushed into the Advanced position, in No.20, White's d-Pawn becomes the head of an Advanced Chain at his Q5 (d5).

1. The King's Gambit Declined, leads to White's Advanced Chain
at his Q5 (d5).

The Chain on Q5 (1 of 2),
After 1.e4 e5 2.f4 Bc5
After 1.e4 e5 2.f4 Bc5, we see a position of the King's Gambit Declined.

White plays the King's Gambit (1.e2-e4 e7-e5 2.f2-f4), but Black declines it, in developing his King Bishop (2...Bf8-c5).

In the diagram (left), I've highlighted all the White Pawns that will be involved in White's Advanced Chain. Regarding White's g-Pawn, while it only has a brief role (16.g2xf3 » 22.f3-f4), it does ensure Black cannot destroy the Advanced Chain before its served its purpose.

The Advanced Chain,
The Chain on Q5 (1 of 2),
After 3.Nf3 to 6...Bb6
After 3.Nf3 to 6...Bb6, there is a period of further development of Center Pawns & Minor Pieces, which leads to White's Advanced Chain at his Q5 (d5).

In the diagram (left), we see the position just before White pushes his d4-Pawn into the Advanced position, at the van of the Advanced Chain (e4,d5).

White developed his King Knight (3.Ng1-f3) and c-Pawn (4.c2-c3) to provide dual support to mobilize the d-Pawn (6.d2-d4), as it has to be developed to a square already under attack (d4, guarded by Black's e5-Pawn).

Technically, Black's Nc6 also attacks White's d4-Pawn. However, the development of White's light-Bishop (5.Bf1-b5) applies a Relative Pin to Black's Knight, which remains in position, to prevent the loss of Black's Bd7. This effectively removes the Nc6's pressure against White's d4-Pawn.

Note: White's 3 Pawn Phalanx (d4,e4,f4) has the chance of forming an Advanced Reverse Salient, if White can push both the d- & f-Pawns onto their respective 5th Rank squares (d4-d5 & f4-f5). In the game, this never happened, as Black's e5-Pawn captured White's f4-Pawn (8...e5xf4).

After 7.d5, White gains the Advanced Chain at his Q5 (7.d4-d5).

Even though Black has nothing attacking White's d5-Pawn, note White's Qd1, without ever having to be moved, provides dual support to the d5-Pawn, along with the e4-Pawn.

After 7.d5 Nb8
After 7.d5 Nb8, As White gains his Advanced Chain (7.d4-d5), Black's Nc6 is forced to flee (7...Nc6-b8), which wastes a Tempo, as it's effectively "un-developing" itself.

(RESULT) The Advanced Chain,
The Chain on Q5 (1 of 2),
After 8.Bd3
After 8.Bd3, White appears uninterested in exchanging light-Bishops. After Black's Knight has returned to b8, it exposed Black's Bd7 to White's Bb5. However, White chose instead to return his Bishop closer to home (8.Bb5-d3), and to keep its presence on the board.

I was always under the impression White wanted to trade light-Bishops, especially with the Bb5 Pin against the former Nc6. But, perhaps that was only a bit of insurance, by White, while he completed his objective of getting his d-Pawn to the head of the Advanced Chain?

(RESULT) The Advanced Chain,

After 8...exf4 9.Bxf4
After 8...exf4 9.Bxf4, White loses his chance to form an Advanced Reverse Salient, as Black's e-Pawn is sacrificed to exchange White's f4-Pawn off the board (8...e5xf4).

White's dark-Bishop completes the trade (9.Bc1xf4), as it's developed.

Note: in the process of Black's e-Pawn exchanging itself for White's f4-Pawn, White has gained two advantages: 2-v-1 (Pawns in the Center), and 4th v. 3rd (e4-Pawn v d6-Pawn).

After 10...Bg4 » 15...Bxf3 16.gxf3, White enchances his Advanced Chain, resupplying it with the g-Pawn.

White's Nf3, having been Pinned for a time by Black's light-Bishop (10...Bd7-g4), is allowed to be exchanged off the board (15...Bg4xf3). But, in doing so, it allows White's g-Pawn to complete the trade (16.g2xf3), to form the new base of White's Advanced Chain (f3,e4,d5).

Note: in the process of Black's light-Bishop exchanging itself for White's Nf3, White has gained the advantage of the Bishop Pair.

After 21...Nh5 22.f4 Nxg3 23.hxg3, White prepares to dissolve his Advanced Chain, by advancing his f-Pawn (22...f3-f4) and allowing his dark-Bishop to be exchanged (21...Nf6-h5 » 22...Nh5xg3), in order to trade his h-Pawn across onto the g-file (23.h2xg3).

Now, White's f4- & g3-Pawns provide the base structure, ready for White to dissolve his Advanced Chain at his Q5 (d5), by advancing his e4-Pawn, so that it becomes the van of a new Advanced Chain at his K5 (e5).

White's Advanced Chain at his Q5 (d5) has been successful, as it has enabled White to transition this advantage into a subsequent advantage (the newly formed Advanced Chain), to maintain White's offensive with his Pawns.

Summary of the Chain on Q5 (1 of 2)...

  1. The King's Gambit Declined, can lead to White gaining an Advanced Chain at his Q5 (d5).

  2. White gains a 3-Pawn Phalanx, which threatens to become an Advanced Reverse Salient (d4-d5, e4, f4-f5).

  3. White gains the Advanced Chain at his Q5 (d5), after a period of further development of Center Pawns & Minor Pieces, which reinforces support for his d4-Pawn (3.Ng1-f3 & 4.c2-c3), while applying a Bishop Pin (5.Bf1-b5) to relieve pressure from Black's Nc6.

  4. White re-supplies his Advanced Chain, with the g-Pawn (16.g2xf3), when it completes the exchange of Black's light-Bishop, for White's Nf3. However, the newly arrived f3-Pawn only acts as temporary support, as it will be moved on again, as White gears up to dissolve his Advanced Chain on Q5 (d5), as the focus will switch to creating a new Advanced Chain on K5 (e5).

  5. White continues his preparation to dissolve his Advanced Chain on Q5 (d5), as his h-Pawn (23.h2xh3) completes an exchange of Black's Knight for White's light-Bishop, to become the base of what will become White's Advanced Chain on K5 (e5).

  6. White's Rook Battery supports the imminent creation of the Advanced Chain on K5 (e5), when the e4-Pawn will be pushed forward.

  7. White dissolves his Advanced Chain on Q5 (d5), pushing the e-Pawn forward (28.e4-e5), to create the new Advanced Chain on K5 (e5), transferring one advantage to another for a successful conclusion to White's Advanced Chain on Q5 (d5).
