After 1.e4 e5 2.f4, we see the position of the King's Gambit, played by White.

I've highlighted all four Pawns that will be involved in White's Advanced Chain at his KB5 (f5).

After 2...Bc5, we see a position of the King's Gambit Declined.

Black declines the opportunity to capture White's f-Pawn, choosing instead to attack White's Ng1, with his dark-Bishop (2...Bf8-c5).

2. White gains the Advanced Chain at his KB5 (f5)

After 3.Nf3 to 6...Nge7
After 3.Nf3 to 6...Nge7, both sides continue the development of their Minor Pieces and Center Pawns. At this point, each side has:
  1. Advanced their d-Pawns, forming a Chain up to their respective K4 squares (3...d7-d6; 6.d2-d3).

  2. Applied a Relative Pin against opposition Knights, with their light-Bishops (5.Bf1-b5 Bc8-g4).

However, White is the only side in a position to create an Advanced Chain, due to the presence of his f4-Pawn, in Phalanx formation alongside his e4-Pawn.

After 7.h3 Bxf3 8.Qxf3, Black trades his light-Bishop to remove White's Nf3 from the board.

The exchange occurs following the threat to Black's light-Bishop, by White's h-Pawn (7.h2-h3).

Instead of withdrawing his Bishop to safety, Black opts to take-out White's King Knight (7...Bg4xf3). White's Queen completes the trade (8.Qd1xf3).
The loss of Black's light-Bishop from the board also negatively impacts on White, when he decides to create his Advanced Chain at his KB5 (f5).

Following Black's decision to Castle Kingside (8...O-O), White pushes his f-Pawn into an Advanced position (9.f4-f5), to become the vanguard in White's Advanced Chain (c2,d3,e4,f5).

After 9.f5 Nd4, White gains the Advanced Chain at his KB5 (9.f4-f5). Black's response is to send his Queen Knight to occupy the d4-Outpost (9...Nc6-d4).

Black's Nd4 now threatens an exchange, to remove White's Bb5.

After 10.Qg3 Nxb5 11.Nxb5
After 10.Qg3 Nxb5 11.Nxb5, Black exchanges his Knight (Nd4) for White's light-Bishop.

As it occupies the d4-Outpost, Black's Knight forces White to get his Queen to safety (10.Qf3-g3). Black follows this up by sacrificing his Knight, to exchange White's light-Bishop off the board (10...Nd4xb5).

White's Queen Knight completes the trade (11.Nc3xb5).

After 11...f6, Black advances his f-Pawn (11...f7-f6), to blockade White's f5-Pawn.

Now, compare this with No.18 (after 1...f7-f6), where Black plays the very same move, but hasn't exchanged White's light-Bishop off the board.

Here, in No.19, Black has ensured he won't be forced into moving his King out of check (wasting a Tempo), and can maintain his focus on destroying White's Advanced Chain.

After 13...d5 » 14...c6, Black continues preparations for destroying White's Advanced Chain.

Black develops his d- & c-Pawns, in that order, to construct another Chain, which is rolled out to his Q4 (d5). The d5-Pawn now attacks the first support (e4) in White's Advanced Chain.

In the midst of all that, White Castles Kingside (14.O-O).

After 15.Na3 Qb6 16.Qxb6 axb6, Black forces an exchange of Queens, prior to dismantling White's Advanced Chain.

The earlier advance of Black's c-Pawn forces White's Nb5 to flee (15.Nb5-a3).

Black's Queen steps out (15...Qd8-b6) to issue a direct challenge to White's Queen. Due to the Absolute Pin, and nothing else defending his Queen, White is forced to exchange Queens (16.Qe3xb6), with Black's a-Pawn completing the trade (16...a7xb6).

Black has deliberately taken on Doubled Pawns (b7,b6), but the removal of White's Queen has Simplified the position, increasing the potential success of his imminent attack to destroy White's Advanced Chain.

After 17.c3, White advances his c-Pawn (17.c2-c3), removing it from his Advanced Chain. This appears to be an attempt to prevent Black gaining an Advanced Chain at his Q5 (d4).

After 17...Rfd8 » 18...Rd7 » 19...Rad8, in successive moves, Black forms his Rooks into a Battery along the d-file, ready for the Opening of the d-file, which will occur when Black exchanges d-Pawns, onto e4, as he begins to dismantle White's Advanced Chain.

After 20...dxe4 21.dxe4, Black attacks White's Advanced Chain, reducing it from 3- to 2-Pawns, as he uses his d-Pawn to take-out White's e-Pawn (20...d5xe4).

White maintains his Advanced Chain, by replacing the original e4-Pawn, with his c-Pawn, as it comes across to complete the trade (21.d3xe4). However, White now only has two Pawns in the Advanced Chain.

After 21...Nc8 to 25...c5, Black delays the destruction of White's Advanced Chain, to escort the Queenside Pawns forward, to their front line (...b6-b5 & ...c6-c5, respectively).

After White's Advanced Chain has been destroyed, Black will go on to resolve his own Pawn Weakness (Doubled Pawns on the b-file), to give White two more Isolated Pawns (a2 & c3).

Due to their vulnerability, Black's Knight escorts the Queenside Pawns to their front line (21...Ne7-c8 » 22...b6-b5 » 23...Nc8-b6 » 24...Nb6-a4 » 25...c6-c5).

After 26...g6 27.fxg6 hxg6
After 26...g6 27.fxg6 hxg6, Black's g-Pawn (26...g7-g6) forces White to dissolve his Advanced Chain, which he does by voluntarily removing his vanguard Pawn, to capture Black's g6-Pawn (27.f5xg6).

Black's h-Pawn completes the trade (27...h7xg6).

Black now has a Qualitative Pawn Majority, on the Kingside, as Black has all his Pawns connected on adjacent files, while White's three Pawns are split into 2x Pawn Islands, with the e4-Pawn being Isolated.

Black's chances of of forcing through a Passed Pawn have markedly improved, and indeed that's just what happened (after 40...Nc5xe4+).

Summary of the Chain in the King's Gambit Declined (2 of 2)...


[Jump to ChessFlash Viewer]

Comparison between successful (No.18) & unsuccessful (No.19)
Advanced Chains in the King's Gambit Declined...

In both No.18 & No.19, White created an Advanced Chain at his KB5 (f5), following the King's Gambit Declined.

In No.18, White's Advanced Chain was reportedly successful, as it played a part in White's victory. In No.19, White's Advanced Chain was unsuccessful, being destroyed en route to White losing the game.

The following analysis compares the two situations to see what might lead to the Advanced Chain at White's KB5 (f5) either being a success or a failing (being destroyed without gaining any transitional benefit -- e.g. supporting an attack on the enemy King).

My analysis focuses on what H&M-S say about White playing f4-f5, in No.19: "The move is suspect on its face," because ...

1. "Black's queen bishop is not on the board to be cramped"

In No.18 (before 1.f4-f5, below-left), Black's light-Bishop is still on the board (Bd7). White can advance his f-Pawn into the Advanced Chain and, in doing so, Black's light-Bishop occupy e6 or g6, and won't be able to attack beyond f5, to g4 or h3. Black's light-Bishop will be less effective, because of this Cramp.

Point Count Chess - IE - Comparison 1, White's Unsuccessful Advanced Chain -- Diagram 19
(COMPARISON 1), White's Unsuccessful Advanced Chain
No.19, Before 9.f4-f5

In No.19 (before 9.f4-f5, above-right), Black's light-Bishop is no longer on the board, as Black had already chosen to exchange it, to remove White's King Knight (7...Bg4xf3 8.Qd1xf3). This should have been one of the signals advising White against forming the Advanced Chain.

2. "Black's P-Q4 (...d6-d5) can be backed up by heavy pieces quickly, since his center is not obstructed, and in fact his minor pieces are ideally posted"

In No.18 (before 1.f4-f5, below-left), Black's light-Bishop is blocking the path through his d6-Pawn. This prevents Black from backing up the d-Pawn, with either Queen or the Rooks, in order to advance the d-Pawn (...d6-d5) to attack White's e4-Pawn, in the Advanced Chain.

Point Count Chess - IE - Comparison 2, White's Unsuccessful Advanced Chain -- Diagram 19
(COMPARISON 2), White's Unsuccessful Advanced Chain
No.19, Before 9.f4-f5

In No.19 (before 9.f4-f5, above-right), due to the absence of Black's light-Bishop from d7 (as it was in No.18), Black already has his Queen (heavy piece) backing up the d6-Pawn, and supporting its advance to Black's Q4 (13...d6-d5). Later, Black is able to provide his Rooks (also heavy pieces), to back up the d5-Pawn (17...Rfd8 » 18...Rd7 » 19...Rad8), prior to striking into White's e4-Pawn, in the Advanced Chain (20...d5xe4).

3. "Black threatens N-Q5, which at the very least will get rid of White's king bishop (Bb5)"

In No.18 (before 1.f4-f5, below-left), Black risks allowing White to exchange light-Bishops (e.g. Bb5xd7 Qd8xd7), if he plays N-Q5 (...Nc6-d4). Black doesn't play that move, and White's Bb5 allowed to remain there of his own free will.

Point Count Chess - IE - Comparison 3, White's Unsuccessful Advanced Chain -- Diagram 19
(COMPARISON 3), White's Unsuccessful Advanced Chain
No.19, Before 9.f4-f5

In No.19 (before 9.f4-f5, above-right), Black has already exchanged his light-Bishop (on his own terms, which I guess makes the difference?), so Black can afford to play N-Q5 (9...Nc6-d4). Black got rid of White's light-Bishop, in an exchange with his Knight (10...Nd4xb5 11.Nc3xb5).

4. "White is too undeveloped to dream of a quick king-side pawn storm."

Er, not sure about this one... I understand the need to be appropriately developed, first. But, when H&M-S say "too undeveloped," the only major difference between the two is the matter of White Castling Kingside ...

And yet, in No.18, despite the tiny difference, White is successful with his Advanced Chain. So, is Castling really just the difference between being "too undeveloped" to make a quick king-side pawn storm?

In No.18 (before 1.f4-f5, below-left), White has already Castled Kingside. Note the loss of White's Queen Knight.

Point Count Chess - IE - Comparison 4, White's Unsuccessful Advanced Chain -- Diagram 19
(COMPARISON 4), White's Unsuccessful Advanced Chain
No.19, Before 9.f4-f5

In No.19 (before 9.f4-f5, above-right), White hasn't yet Castled. Now note the presence of White's Queen Knight (Nc3), but the loss of his King Knight (7...Bg4xf3), and the short advance of his h3-Pawn. Does this mean all White had to do was Castle first (e.g. 9.O-O), and White would be "developed enough"? Because that, to me, is what H&M-S are implying here.

In conclusion ...

Putting the confused matter of development to one side, for now, it would seem the biggest indicator, as to whether White should advance his f-Pawn into the Advanced Chain, is the presence of Black's light-Bishop ...

In other words, IF Black's light-Bishop can be Cramped (e.g. because it's either undeveloped on c8, or has been developed, to d7), then White can be confident in playing f4-f5, to create the Advanced Chain.

And, I suppose, IF Black's light-Bishop is no longer on the board, then it MAY be wiser to exchange the f-Pawn onto e5 (f4xe5), to give White 2-v-1 in the Center, which H&M-S suggest in No.18 (before 1.f5).
