Doubled Pawns
Doubling Away from the Center (2 of 2)

Point Count Chess, NO.70, p101
Rubinstein v. Canal, 1929

This example shows how White can thrive with Doubled Pawns on the f-file, and is in complete contrast to No.69, where the same Doubled f-Pawns proved to play a significant role is White's downfall.

1. How White's e-Pawn become Doubled, on the f-file.

 Doubled Pawns,Doubling Away from the Center (2 of 2), After 1.d4 to 8.Qc2 After 1.d4 to 8.Qc2, despite slightly different play to that seen in No.69, once again there's the same two core similarities: Tension between the Pawns at c4 & d5. White's e3-Pawn supporting the Bf4* (* Black will exchange this unit, to force White's e3-Pawn to become Doubled on the f-file).
 Doubled Pawns,Doubling Away from the Center (2 of 2), After 8...dxc4 9.Bxc4 After 8...dxc4 9.Bxc4, White gets the two Center Pawn advantages: ... and they're both given to White, as Black's d5-Pawn captures White's c4-Pawn (8...d5xc4), breaking the tension and forcing the exchange of Pawns, on c4, with White's light-Bishop completing the trade (9.Bf1xc4). This is a significant difference to No.69, where White was first to break the tension, to capture Black's d5-Pawn.
 Doubled Pawns,Doubling Away from the Center (2 of 2), After 9...Nb6 10.Bb3 Nd5 After 9...Nb6 10.Bb3 Nd5, using both Knights, Black enables an attack on White's Bf4, in the build-up to exchanging a Knight, to force White's e3-Pawn to become Doubled on the f-file. First, Black's Queen Knight (9...Nd7-b6) defends the d5-square, from White's light-Bishop, which is driven back by the Nb6 (10.Bc4-b3). And then Black's King Knight is able to move to the d5-Outpost (10...Nf6-d5), to attack White's Bf4.

Black's Nb6 ensures he'll be able to maintain a Knight attack on White's Bf4, in the event White chose to capture the current Nd5, with his Bb3.

 Doubled Pawns,Doubling Away from the Center (2 of 2), After 11.O-O Nxf4 12.exf4 After 11.O-O Nxf4 12.exf4, White's e3-Pawn is forced to Double Away from the Center, onto the f-file, as it completes the Minor Piece exchange on f4. Despite his Bf4 coming under attack from Black's Nd5, White chooses to spend his next move Castling Kingside (11.O-O). Black's Nd5 immediately captures White's Bf4 (11...Nd5xf4), forcing White's e3-Pawn to complete the trade (12.e3xf4), to become Doubled on the f-file.

The overall objective for White's h-Pawn is to swap it off the board, to Open the h-file, up to Black's Kingside Castled King.

In successive moves, White's g-Pawn is advanced up the g-file (25.g3-g4 » 26.g4-g5), to blockade Black's g-Pawn, and guard the f6-square: Blockading Black's g-Pawn prevents it potentially removing White's f4-Pawn, which co-supports White's Ne5-Outpost. Guarding the f6-square prevents Black's Backward f7-Pawn from advancing to attack and chase White's Ne5 off its Outpost.

Summary of Doubling Away from the Center (2 of 2)...

1. The whereabouts of Black's e-Pawn appears to be the key difference between determining whether White's Doubled f-Pawns will be a fatal weakness, or an asset that can be used for victory.

2. If Black's e-Pawn remains on e6, because Black chooses to break the tension by capturing White's c4-Pawn (No.70, 8...d5xc4), then it serves to strengthen White's opportunities, when he incurs the Doubled f-Pawns.

3. If Black's e-Pawn completes the Pawn exchange on d5, because White chooses to break the tension by capturing Black's d5-Pawn (No.69, 5.c4xd5), then it serves to increase the vulnerability of White's Doubled f-Pawns (when incurred). Black's light-Bishop will be able to focus on White's weak light-squares on the Kingside, as White's g-Pawn will leave Holes at f3 & h3, when it's forced to advance (No.69, 10.g2-g3), to provide support for White's leading Doubled f-Pawn (f4).

4. White's Isolated d4-Pawn appears to be safe enough, whether White's Doubled f-Pawns are deemed to be an asset or a fatal weakness (see Comparison 3, below, for full details).

Comparison between No.69 (Doubled f-Pawns = White Loses)
& No.70 (Doubled f-Pawns = White Wins)...

Black's e-Pawn is the one key difference, between No.69 and No.70 that turns Doubled f-Pawns from being a fatal weakness, into being an asset that can assist in White's victory.

1. THE KEY DIFFERENCE: the adverse Center Pawn structure.

In No.69 (after 7...Nh5, below-left), we see the position just before Black's Nh5 captures White's Bf4, to force White's e3-Pawn to become Doubled, on the f-file.

White already has a 2-v-1 advantage, while Black has a 4th v. 3rd advantage (Black's d4 v. White's e3), following the completion of the Pawn exchange, on d5, by Black's e-Pawn (5.c4xd5 e5xd5).

 (COMPARISON 1) Doubled f-Pawns = Fatal Weakness, No.69, After 7...Nh5 (COMPARISON 1) Doubled f-Pawns = Asset, No.70, After 10...Nfd5

In No.70 (after 10...Nfd5, above-right), we see the position just before Black's Nd5 captures White's Bf4, to force White's e3-Pawn to become Doubled, on the f-file.

However, in this case, Black's e-Pawn is still at e6, while White's Center Pawns have both advantages: 2-v-1 and 4th v. 3rd (White's d4 v. Black's e6).

2. How this key difference impacts both sides, once White incurs Doubled Pawns, on the f-file.

In No.69 (after 9.exf4, below-left), White incurs Doubled Pawns, on the f-file.

Because Black's former e-Pawn is now on d5, this benefits Black's light-Bishop, which will be able to focus on White's weak squares on the Kingside: once White's g-Pawn has been forced to step forward, to support White's leading Doubled f-Pawn (f4), it will leave Holes at f3 and h3 (weak squares).

In addition, because Black's former e-Pawn is no longer on e6, Black can advance his f-Pawn, to f6, to stop White's King Knight occupying the e5-Outpost. If Black still had his e-Pawn on e6, Black's f-Pawn couldn't move to f6, without making the e6-Pawn Backward (a Weak Pawn, for White to target!). But that's not a problem, here.

 (COMPARISON 2) Doubled f-Pawns = Fatal Weakness, No.69, After 9.exf4 (COMPARISON 2) Doubled f-Pawns = Asset, No.70, After 12.exf4

In No.70 (after 12.exf4, above-right), White incurs Doubled Pawns, on the f-file.

Because Black's e6-Pawn cannot advance, Black's light-Bishop becomes a Bad Bishop, which cannot be freed of its weakness (low mobility) until Black can find a way of clearing the light-squares on the Queenside (of course, as we've seen, above White's a- & b-Pawns advance, to prevent Black's counterplay, via ...c6-c5, which would help give Black's light-Bishop its freedom).

In addition, the problem of Black's e6-Pawn impacts on Black's ability to prevent White's King Knight from gaining a positional advantage, when it occupies the e5-Outpost. Black cannot risk making his e6-Pawn Backward, to cannot advance his f7-Pawn (...f7-f6) to deny White's Nf3 access to e5.

Black's e6-Pawn also causes Black's army Cramp, preventing Black's Pieces from expanding through the Center, which further impacts on Black's ability to counter, as White expands and attacks on the Kingside.

3. The security of White's Isolated d4-Pawn

In No.69 (after 9.exf4, below-left), appears to be a little safer, since it would become un-Isolated, if Black were to attack it with his c-Pawn (e.g. 1...c6-c5, then 2.d4xc5 removes the Pawn from its isolation, with 3.b2-b4, to support White's former Isolated d-Pawn).

 (COMPARISON 3) Doubled f-Pawns = Fatal Weakness, No.69, After 9.exf4 (COMPARISON 3) Doubled f-Pawns = Asset, No.70, After 12.exf4

In No.70 (after 12.exf4, above-right), while White's d4-Pawn can be attacked from the front (as it is at present, by Black's Queen), H&M-S point out that it's safe front such danger, as: "White can defend it sufficiently with pieces that are also active in other directions:"

• White's Queen Rook can defend from behind (Ra1-d1), while White focuses on Opening the h-file. White's Rook can then be moved from d1 to h1, to join in a potential Mating attack, once the h-file is Opened.

In addition, Black's inability to coordinate his heavy Pieces through the Center, because of the central Cramp caused by Black's e6-Pawn, means White's Isolated d4-Pawn isn't in any danger.
