The Bishop-pair

 PCC, The Bishop-pair. Example #1 The Bishop-pair (1 of 3) (p205-206) Diagram NO.142 Example Sequence The Bishop-pair (1 of 3) This example highlights the disadvantage of having a Bishop & Knight, versus an opponent with both Bishops (the "Bishop-pair").
 PCC, The Bishop-pair. Example #1 The Bishop-pair (2 of 3) (p206) Diagram NO.143 Tarrasch v. Teichmann, 1905 The Bishop-pair (2 of 3) This example highlights the need for the Bishops to have Space and Mobility, in order to be effective. In No.143, White manages to create the conditions needed for his Bishop-pair to be an effective pairing.
 PCC, The Bishop-pair. Example #1 The Bishop-pair (3 of 3) (p207) Diagram NO.144 Nimzowitsch v. Levenfish, 1911 The Bishop-pair (3 of 3) This example, like No.143, also highlights the need for the Bishops to have Space and Mobility, in order to be effective. However, in No.144, Black never manages to create the conditions that enable his Bishop-pair to become the potent weapon that they otherwise should be.
 PCC, The Bishop-pair. Example #2 The Ruy Lopez Question (1 of 2) (p208) Diagram NO.145 Example Sequence The Ruy Lopez Question (1 of 2) White has structural superiority and the two Knights. Black has Doubled Pawns, but the Bishop-pair. The Question: Which has the better game? This article just raises the question. The next part (2 of 2, below), looks at an example game, where the Bishop-pair prove superior.
 PCC, The Bishop-pair. Example #2 The Ruy Lopez Question (2 of 2) (p208-209) Diagram NO.146A to NO.146C Taubenhaus v. Tarrasch, 1903 The Ruy Lopez Question (2 of 2) This example helps to answer the Ruy Lopez Question. It seems the Bishop-pair can triumph by taking-out one of White's two Knights, reducing White to Bishop & Knight versus Black's two Bishops. In addition, Black's Doubled Pawns can be turned into an asset, used to restrict White's space and mobility, on White's Queenside.
 PCC, The Bishop-pair. Example #3 The Bishop-Pair in the Queen's Gambit (p210) Diagram NO.147 Example Sequence The Bishop-Pair in the Queen's Gambit This is almost a Reverse Ruy Lopez Question. But, instead of Black gaining the Bishop-pair and the Doubled Pawn structure, it's White who gets them. However, the additional structural weakness, for White, is he also gains an Isolated Pawn (a3).
