(Offside Pawn Majority)

Pawn Majorities
Offside Majority v. Minority Attack (2 of 2)

Point Count Chess, NO.187, p265-266
Marshall v. Capablanca, 1909

This example shows Black succeeding with the Offside Pawn Majority, on the Queenside, versus White's Minority Attack.

It appears White made an error that might have saved him, by persevering with his Minority Attack, instead of switching to a possible advance in the Center, when it appeared that Black had met the conditions to keep his Offside Pawn Majority "mobile."

Pawn Majorities,
Offside Majority v. Minority Attack,
(2 of 2), After 1.d4 to 3...c5
After 1.d4 to 3...c5, Black gets his c-Pawn to its fourth rank (3...c7-c5), which is significant to Black's intentions for gaining the Offside Pawn Majority, on the Queenside.

As mentioned in No.186, as well as taking on the Pawn Minority, the opposition will gain the benefit of the Half-open c-file.

If the side with the Offside Pawn Majority (Black, in this case) is to be successful, the Pawn Majority must be kept "mobile", and the best chance of doing this is to get the c-Pawn out to the fourth rank ...

... and to keep it ahead of its fellow Majority Pawns (otherwise, the c-Pawn risks becoming Backward, on the Half-open c-file, which will hamper the Offside Wing's mobility).

Offside Majority v. Minority Attack,
(2 of 2), After 4...exd5
After 4...exd5, Black gains the Queenside Pawn Msjority, following an exchange of Pawns onto d5. This will eventually become Black's "Offside Pawn Majority." White will have to settle for the "Minority Attack," on the Queenside.

Note: White currently has the Kingside Pawn Majority, but with both Kings set to Castle to the Kingside, White will have the "Onside" Pawn Majority, which is inferior to the "Offside" Pawn Majority, when it comes to trying to convert a Passed Pawn and get it Promoted.

After 8.O-O Nf6, White Castles Kingside (8.O-O). Black develops his King Knight (8...Ng8-f6) clears his back rank, on the Kingside, and is now ready to Castle Kingside (and gain the Offside Pawn Majority, in the process).

12.Nxe4 dxe4
After 11...Nxd4 12.Nxe4 dxe4, Black reduces his Queenside Pawn Majority, down to a more-favorable 3-v-2.

Black posts his Queen Knight onto the d4-Outpost, in the process of capturing White's d4-Pawn (11...Nc6xd4).

White, not content with leaving Black with two Outpost Knights in the Center, opts for an exchange of Knights on e4 (12.Nc3xe4 d5xe4), creating Black's 3-v-2 Queenside Majority.

The Result of the Offside Majority v. Minority Attack (2 of 2)...

Point Count Chess - IE - Diagram 187 - Pawn Majorities, Offside Majority v. Minority Attack (2 of 2), After 15...O-O
(RESULT) Pawn Majorities,
Offside Majority v. Minority Attack,
(2 of 2), After 15...O-O
After 15...O-O, before any further moves are made, H&M-S recommend that White leaves his Queenside Pawn Minority in their current position, and instead focus on building an attack through the Center.

H&M-S say: "White's best chance is a center advance, say P-K4, Q-K3, and P-KB4 (e3-e4, Qf3-e3, and f2-f4)."

The reason is most likely to be the position of Black's c-Pawn, which has already reached its fourth rank, on the Half-open c-file. For reasons outlined in No.186, Black can maintain the "mobility" of his Offside Pawn Majority. White would need it "immobilized," to have any chance of succeeding with his Minority Attack. Hence, the recommendation by H&M-S, to focus instead on an advance through the Center.

Unfortunately, for White, he pursued his Minority Attack ...

After 26...Rd1+ 27.Kg2 a5, Black continues to keep his Offside Pawn Majority mobile.

After 28...b4 29.axb4 axb4, Black's Offside Pawn Majority is reduced to a 2-v-1 Majority.

Black's b-Pawn advances to attack White's a3-Pawn (28...b5-b4).

White exchanges his a-Pawn (29.a3xb4), and Black's a-Pawn completes the trade (29...a5xb4), leaving himself with the 2-v-1 Offside Pawn Majority.

After 31...b3 32.Rd1, Black continues to keep his Offside Pawn Majority "mobile," with the advance of his replacement b-Pawn (31...b4-b3).

White cannot capture Black's Backward c4-Pawn, because of the presence of Black's Be6. Therefore, White's Rook must flee the attack by Black's b3-Pawn (32.Rc2-d2).

After 34...b2 35.Rxb2 Rxd1, Black allows his Passed b-Pawn to be sacrificed (34...b3-b2 32.Rd2xb2), in order to take-out White's light-Bishop (35.Rc1xd1).

After 36.Rc2 Bf5 37.Rb2 Rc1, White tries to get his Rook behind the Passed c-Pawn (36.Rb2-c2), in the hope of escorting it up to gain Promotion.

However, Black's light-Bishop chases the Rook away (36...Be6-f5 37.Rc2-b2) and then Black's Rook returns to the c-file (37...Rd1-c1), ensuring White can neither get his c-Pawn Promoted, nor take his Rook away from guarding the beleaguered c-Pawn.

This enables Black to switch his focus to his "Onside" Minority Attack, over on the Kingside ...

After 43...f5+ 44.Kg3, Black's f-Pawn is developed (43...f7-f5+), primarily to Blockade White's f4-Pawn, but the move also forces White's King to retreat (44.Kg4-g3).

Summary of the Offside Majority v. Minority Attack (2 of 2)...

  1. The Offside Pawn Majority is more likely to succeed if it can be kept "mobile." The Minority Attack needs the Offside Pawn Majority "immobilized," if it's to succeed. Both No.186 & No.187 suggest that, if you have the Pawn Minority, on the "Offside," at the point when your opponent gains the Offside Pawn Majority; your Minority Attack is likely to fail if the enemy's c-Pawn has reached its fourth rank, and is ahead of its fellow Pawns in the Majority group, since it is likely the Offside Pawn Majority can be kept "mobile."

  2. If it appears the enemy's Offside Pawn Majority can be kept mobile, switch your focus from launching your Minority Attack, to mobilizing for an attack either in the Center, or on the opposite flank. For example, in No.187, after 15...O-O, H&M-S suggested a "center advance," would be "White's best chance." In the game, White ignored this option, proceeded with his Minority Attack, and eventually lost the game.

  3. The Offside Pawn Majority may be purely a Decoy, designed to keep the enemy from succeeding with his "Onside" Pawn Majority. In No.187, Black showed that, while his Offside Pawn Majority may generate a Passed Pawn (34.b2xc3), it occupied White's time, with the threat to Promote the Passed Pawn, preventing White's only surviving Rook from helping to force a Passed Pawn on the Kingside. This helped improve Black's chance of succeeding with his "Onside" Minority Attack, against the enemy's 4-v-3 Pawn Majority.

  4. Key blockades of the e- & f-Pawns, in the "Onside" Pawn Majority, plus the King, play a key role in succeeding with the "Onside" Minority Attack.
