Doubled Pawns

 PCC, Doubled Pawns. Example #1 Endgame Weakness (p93-94) Diagram NO.62A to NO.62B Cohn v. Rubinstein, 1909 Endgame Weakness An exchange on f3, by Black's light-Bishop, for White's King Knight, results in White's Doubled Pawns on the f-file. In addition to Doubled Pawns, White's h-Pawn becomes an Isolated Pawn, and it's this weakling that Black's King focuses on, while Black's Kingside Pawns take-on White's Doubled Pawn weakness. Black's plan is to deal with White's weak Pawn structures on the Kingside, before freeing one of his other Pawns, and guiding it down to gain Promotion.
 PCC, Doubled Pawns. Example #2 The Doubled Queen Bishop Pawn in the Queen Pawn Opening (p94) Diagram NO.63 Example Sequence The Doubled Queen Bishop Pawn in the Queen Pawn Opening An exchange on c3, by Black's dark-Bishop, for White's Queen Knight, results in White's Doubled Pawns on the c-file. It also leaves White's a-Pawn Isolated, and creates a Hole at b3. However, H&M-S suggest White benefits more from having the Doubled Pawns reinforce the Center, although there appears to be equal opportunity to win or lose, from this position (for both sides).
 PCC, Doubled Pawns. Example #3 File-Opening (p96) Diagram NO.64 Kostic v. Capablanca, 1919 File-Opening This example serves as a warning to the player about to force their opponent to take on Doubled Pawns. In certain cases, the Doubled Pawns will become a weakness that can be exploited. In other cases, the opponent can benefit from the opening of the file. Includes a Comparison of the value of files that are opened, as a result of the Doubled Pawns, (comparing No.63 and No.64).
 PCC, Doubled Pawns. Example #4 The Pinned King Knight (1 of 2) (p98) Diagram NO.66 Capablanca v. Dus Chotimirsky, 1913 The Pinned King Knight (1 of 2) While the focus in this example is Black's Bishop Pin on White's Nf3, and the possibility of White incurring Doubled Pawns on the f-file, in the game, White actually avoids the Doubled Pawn formation. The main point to consider is WHY White was able to choose to IGNORE the Doubled Pawn threat.
 PCC, Doubled Pawns. Example #4 The Pinned King Knight (2 of 2) (p98) Diagram NO.67 Maroczy v. Capablanca, 1926 The Pinned King Knight (2 of 2) This example shows Black's King Knight (Nf6) being Pinned by White's dark-Bishop, from g5. However, it also serves to highlight conditions that mean White's effort is wasted, in his play that forces Black to incur Doubled Pawns, on the f-file. In addition, we see how Black can take advantage of the Half-Open g-file, which was created during the Doubling of Black's g- and f-Pawns.
 PCC, Doubled Pawns. Example #5 Doubling Away from the Center (1 of 2) (p100) Diagram NO.69 Alekhine v. Lasker, 1924 Doubling Away from the Center (1 of 2) This example (No.69) is one of two (No.70, being the other) that tries to help a player determine whether it's okay (or not) to allow a center pawn (d- or e-Pawns) to become Doubled upon the bishop file (c or f, respectively). H&M-S stress it's not easy to determine this!
 PCC, Doubled Pawns. Example #5 Doubling Away from the Center (2 of 2) (p101) Diagram NO.70 Rubinstein v. Canal, 1929 Doubling Away from the Center (2 of 2) 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. Includes a Comparison between No.69 & No.70, to help identity one key difference that can help turn White's Doubled f-Pawns from a fatal weakness, to a potential game-winning asset.
 PCC, Doubled Pawns. Example #6 Acceptable Doubled Pawns (p269) Diagram NO.188 Schwarz v. Tarrasch, 1932 Acceptable Doubled Pawns This example shows that Doubled Pawns may be considered acceptable, when exchanging a Bad Bishop, for your opponent's Good Bishop. Black's development leads to his light-Bishop becoming a Bad Bishop. Black then exchanges it for White's light-Bishop (the Good Bishop). Despite incurring Doubled Pawns on the f-file, it serves to strengthen the Center, for Black's benefit.
