The story behind the game
At the 2013 women’s world team event in Astana, Krush’s kingside play includes both pawn advances and a knight retreat. The open g-file becomes useful only after the pieces are reorganized. Follow the route back from g1 to e2 and g3, then compare how the rooks and queen support the final knight jump.
Take these ideas to your next game
- A retreat can be the first step toward a better square.
- Open files need rooks and supporting pieces before they become attacking routes.
- A pawn advance should be checked against the king cover it leaves behind.
- When an attacked rook captures another rook, recalculate the whole attack.

Full game transcript, including the result and the answers. Original explanations by chessgames.info; game score from the sources below.
Krush plays 19.g5, creating a kingside pawn contact. The game later continues gxf6 and …gxf6, clearing the g-file of those two pawns. That opening is useful only if White can bring pieces to it. Compare the resulting king cover and central tension; opening a file is a change to evaluate, not a guarantee of an attack.
The game continues 21.Ng1, beginning a purposeful reorganization. White later uses Ne2 and Ng3 rather than leaving the knight on its original attacking square. Moving backward can improve a piece’s future tasks. Keep track of Black’s central play while planning the route: a manoeuvre needs time and a position that can support it.
Krush plays 30.Rg1, placing a rook on the open g-file. The later Rg2 and Rbg1 double the rooks. The king, queen and minor pieces all affect whether an invasion is possible, so do not judge the file in isolation. Compare Black’s attempts to contest it with the saved candidate lines.
The move 40.Nh5 attacks the g7-rook; the recorded reply is …Rxg2 and White recaptures Qxg2. The attacked rook has a forcing capture, so the knight jump must be calculated beyond the first threat. White’s other rook and queen remain coordinated on the g-file. The game ends after the queen recapture; use the saved analysis for the unplayed continuations rather than inventing a recorded mate.
Result: 1-0. The recorded score ends here; it does not imply checkmate.
