Game 23 of Irving Chernev's Logical Chess: Move by Move is a masterclass in queenside play. Van Vliet opens with the Stonewall Attack, hoping to build a solid centre and launch a kingside assault. But Znosko-Borovsky, playing Black, has other ideas. He strikes at the right moment, seizes the open c-file, and orchestrates a crushing queenside attack with every piece joining the assault. This is one of the most instructive games in the series for understanding how to punish passive, planless play.

The Opening: Stonewall Attack

White sets up the classic Stonewall formation with pawns on d4, e3, f4, and c3. It looks solid, but it has a fatal weakness: the c3-d4 pawn chain leaves the c-file vulnerable, and the dark-squared bishop is permanently hemmed in by White's own pawns.

Black responds with natural, active development, placing pieces on their best squares and waiting for the right moment to strike.

Key Position 1: 8...Nb4! (Move 8, Black to move)

After Black plays 7...cxd4! to wrench open the c-file, the real fireworks begin with 8...Nb4! This knight leaps to b4, attacking White's light-squared bishop, the critical piece in the Stonewall Attack. Without this bishop, White can never generate the kingside attack he needs.

Watch this position in the study:

This is a perfect example of the Piece Activity Count in action. Count the pieces Black has actively mobilised versus White's passive setup. Black is already ahead on active pieces, and he uses that advantage to disrupt White's plans before they can take shape. White is forced to retreat the bishop to the awkward b1-square, losing a tempo and any hope of a coordinated attack.

Key Position 2: 12...Nc2! (Move 12, Black to move)

This is one of the most striking moves in the entire series. After carefully manoeuvring, Black drops the knight into c2, attacking both White rooks simultaneously. White is completely helpless.

Watch this position:

The Rule of Three is beautifully illustrated here. Black has three pieces actively bearing down on White's position: the knight on c2, the bishop on b5 pinning the e2-rook to the queen, and the rook on c8 controlling the open file. Every piece is contributing. White's pieces, by contrast, are tangled and passive. The result is a rook on the seventh rank for Black, almost total paralysis for White, and a won ending.

The Full Game

Znosko-Borovsky converts the advantage methodically in the endgame, pushing his queenside pawns and using precise king activity to force the win. Watch how every pawn and piece works together to the very end.
