Pawn Chain Configurations: Pawn islands 3

Pawn3-01The problem of an isolated pawn is surely worth an independent topic and thorough analysis. For a while let’s confine our study to a particular case from the creativity of great chess players.

I remind you that generally pawns are strong when placed side by side, backing up and protecting each other. There are exceptions, but exceptions only prove the rule.

Viktor Korchnoi is a known expert on French Defense, including the line with an isolated d5-pawn. This makes Anatoly Karpov’s victory in analogical structure with a color change even more valuable a study.

Pawn3-02The isolated d4-pawn doesn’t decorate White’s position. However, while his pieces are controlling square d5, the c3-rook offers an exchange, after which the pawn would have moved to assist its central colleague (b2:c3).

To conclude our series on pawn islands, I offer you an instructive realization of slight advantage in the performance of a member of the Romanian chess team.

What is remarkable, when analyzing the game with a computer, is that I didn’t find any substantial mistakes from the black side. In other words, the win was achieved by slow gradual pressure from the first to the last move. The advantage was steadily gained during the whole, long game.

25. Kb1 b5 An attempt to organize counterplay against the c-pawn looks reasonable. [25…f6 26.c3 Be5 27.Rd2 +/= Stable advantage which is highly unpleasant for the opponent.]

31. Kxc1 The Romanian grandmaster kept his pawns on their initial positions, creating two islands against three of his adversary’s. There is also a potential danger of creating an outside passed pawn on queenside. Nc5
