In this game the black pawns advanced with essentially nothing in their way.
- Anticipating Black's coming pawn advance, White's best here was to retreat the bishop to g2, keeping the key d5 square under control and making the d-pawn's advance harder. But this necessary prophylaxis never came

- Perhaps later White could have managed this regrouping: ♕b4, ♖ac1, c3-c4

- The threat was 20...g4 and then 21...g5

- The pawn knows its job: step by step it moves forward

- It still seems that Black's d-pawn cannot break through to a queen, but let us not rush to conclusions
- 26.
- Now the threat 27...♖c4 28. ♕a3 ♗c8 is very unpleasant
- 27.
- Avoiding one trouble, but running into another

- After this the a-pawn gets a "green light," but what can you advise White?
- ()And Black either forces through d5-d4 or breaks in with the queen along the a7-g1 diagonal

- White resigned — the d-pawn cannot be stopped
