Check & Mate Ending Explained: The Final Match and Mallory's Choice

⚠️ Spoiler Warning: This guide contains detailed spoilers for the entire novel. Proceed only if you've finished reading or are comfortable knowing the plot.

The Literal Outcome: How the Story Ends

Mallory Greenleaf wins the World Chess Championship in Venice, Italy. She defeats Nolan Sawyer in the twelfth game after eleven consecutive draws. The final match takes place in a glass-walled garden, where Nolan, for the first time in his career, wants to play more than he wants to win because he is playing against her. The victory makes Mallory the first woman to qualify for and win a world championship.

The epilogue, set two years later, confirms that Mallory holds the World Champion title and is ranked #5 globally, while Nolan remains the #1 player. They live together in a Tribeca apartment. Nolan has qualified to challenge Mallory in the upcoming Montreal World Championship, setting up a rematch that has captured massive public interest. Chess participation surges, particularly among women.

The Climax in Venice: Chapters 30 and 31

The climactic encounter unfolds early in the morning, before the championship match. Mallory, unable to sleep, walks to the glass house where the game will be held. She finds Nolan studying a portrait of his grandfather, Marcus Sawyer. The scene functions as their full reconciliation after the bitter fight in New York, where Mallory had accused Nolan of manipulating her career and told him she hated him.

Mallory tells Nolan she has been working on herself. She lists what she now wants openly: to play chess professionally, to maintain her friendship with Easton, and to speak about her father with her family—acknowledging the good alongside the bad. Then she confesses she wants to be with Nolan. She speculates about their shared childhood proximity in chess circles, wondering if they were “destined” to meet, before rejecting the notion of fate and instead trusting her own choice.

Nolan responds by telling her that when he is with her, he wants to play more than he wants to win. They embrace. The chapter closes with Mallory feeling as though she is entering a new era of her life.

Six and a half hours later, the mayor of Venice makes the ceremonial first move, queen’s pawn to d4. Mallory looks across the board at Nolan, who smiles at her. The book ends on that image, mid-beginning, leaving the actual games of the match undescribed.

Major Character Outcomes

Mallory Greenleaf

Mallory completes an internal arc from avoidance to action. By the story’s end, she articulates what she wants for herself rather than hiding behind obligations. She decides to pursue chess as a career, rebuild her friendship with Easton, and let Nolan in. Two years later, she is World Champion and cohabitating with Nolan in New York.

Nolan Sawyer

Nolan’s outcome is transformation through vulnerability. His arc peaks when he admits that playing Mallory changes his motivation—the human connection matters more than the title. He keeps the tic-tac-toe note from Toronto, reveals he thinks of her constantly, and in their final Venice conversation offers no competitive advice beyond “make sure you eat breakfast.” The epilogue shows him still the world’s #1, but now set to challenge the woman he lives with.

Mallory’s Family

Sabrina and Darcy discover Mallory’s secret chess career earlier in the novel. Their mother confronts Mallory in Chapter 28, giving her permission to live for herself and offering to be part of her life going forward. The family unit emerges intact and more honest. By the epilogue, Mallory accompanies Darcy to her university drop-off at Brown.

Oz Nothomb and Defne Bubikolu

Oz, Mallory’s initially silent training partner, tells her before the championship that he believes she can win. Defne remains Mallory’s coach throughout. Their fates are not detailed in the epilogue beyond their presence in the chess world.

Malte Koch

Koch cheats in the Challengers tournament, which leads to Mallory inheriting the challenger spot. He also releases a TikTok accusing Nolan of covertly funding Mallory’s Zugzwang scholarship. His on-page role ends as the disgraced antagonist.

Resolved and Unresolved Threads

Resolved

• The scholarship secret: Nolan’s anonymous funding of Mallory’s Zugzwang fellowship is exposed. They fight bitterly over the deception but eventually reconcile in Venice.
• Family secrecy: Mallory’s double life is discovered by Darcy and then the rest of the family. Her mother explicitly frees her from caretaker guilt.
• Mallory’s relationship to chess: She moves from total avoidance to embracing the game as a profession.
• The romance: Mallory and Nolan declare mutual commitment and are living together in the epilogue.

Unresolved

• The Montreal rematch outcome: The epilogue sets up a World Championship match between Mallory and Nolan but deliberately avoids revealing the winner.
• The father’s full story: Mallory begins opening up about her father and even studies some of his old games with Darcy, but the novel does not provide a complete reckoning with his infidelity or his legacy.
• Mallory and Nolan’s relationship status: BBC reporter Eleni Gataki notes that their romantic relationship is rumored but unconfirmed, describing them as regularly photographed holding hands. The text leaves their official status publicly ambiguous.

Theme Resolution

Sacrifice and Family Obligation

Mallory’s mother directly addresses this theme in Chapter 28: “Guilt and responsibility are heavy burdens, but they are also something we can hide behind.” Mallory learns to stop sacrificing her own desires under the guise of duty. For more on this, see themes of sacrifice and family obligation.

Vulnerability and Trust

Mallory’s arc depends on allowing herself to trust Nolan after his secret donation. Her admission “I think I was wrong” to Easton marks the turning point. Nolan’s revelation that it is his first time during their intimate scene and his admission about wanting to “play more than win” both root the theme in mutual vulnerability. See vulnerability and trust.

Sexism in Chess

Koch’s misogyny—calling for touch-move rules selectively, mocking women’s tournaments—remains a background antagonist. Mallory defeating him on the board and eventually claiming the World Champion title serves as a rebuttal. The epilogue explicitly notes a surge in chess popularity among women, tying the personal victory to a broader cultural shift. See sexism in chess.

Underdog vs. Champion

The Venice match pits Mallory, world ranking #1,843, against Nolan, world ranking #1. Her victory is the ultimate underdog triumph. Yet the book complicates the trope: Nolan wants her to win, and the real battle has always been Mallory against her own fear. See underdog vs. champion.

Resilience and Identity

Mallory reconstructs her identity from reluctant mechanic to World Champion. Defne’s mentorship, Oz’s quiet belief, and her family’s eventual support all reinforce that Mallory’s resilience is not solitary but community-supported. See resilience and identity.

The Epilogue: A New Challenge

The epilogue takes the form of a BBC article by Eleni Gataki headlined “The Next World Chess Championship, and the Fact That Everyone Is Talking About It—Explained.” Gataki outlines five factors driving unprecedented interest:

1. Nolan Sawyer’s celebrity as the current #1.
2. Mallory Greenleaf’s “unusual path” and status as the first female World Champion.
3. Persistent rumors about their romantic relationship.
4. The narrative charge of them facing each other in Montreal—living together, possibly brushing their teeth side by side, then sitting across a chessboard.
5. A general cultural moment where chess has become “cool.”

The article notes that Mallory defeated Nolan in the twelfth game after eleven draws, but declines to confirm they are a couple, framing the Montreal rematch as a public fascination precisely because the personal stakes remain uncertain.

Six Reader Questions About the Ending

1. Does Mallory actually win the World Championship?

Yes. The epilogue confirms she defeated Nolan Sawyer in Venice and is the reigning World Champion. Her ranking of #5 reflects the fact that rankings aggregate all tournament results, while the champion title is decided by a specific match.

2. Do Mallory and Nolan end up together?

Yes. They reconcile in Venice, and the epilogue reports they live together in a Tribeca apartment. They are photographed holding hands, attend family events together, and an onlooker describes Nolan playfully biting Mallory’s ear at a tournament. The BBC article stops short of calling them a couple only because they have not publicly confirmed it.

3. Why did Mallory fight Nolan in New York?

Mallory learned Nolan anonymously funded her Zugzwang scholarship. She interpreted this as manipulation—an attempt to engineer her as his World Championship challenger. Nolan insisted the donation was for her benefit. Mallory, already primed to distrust due to her father’s betrayals, reacted by calling him selfish and unloved. The fight was as much about her family history as it was about the money.

4. What did Mallory’s mother tell her that changed things?

Her mother said that when she thinks of chess, she thinks of Mallory playing and “kicking ass,” not of her ex-husband’s affairs. She released Mallory from the burden of protecting her and told her to make a choice for herself without hiding behind guilt. This permission lets Mallory decide to pursue Nolan and the championship on her own terms.

5. What happens to Oz and Defne at the end?

Neither Oz nor Defne receives a specific epilogue mention. In the final Venice scenes, Oz tells Mallory he believes she can win anything she sets her mind to. Defne continues coaching her through pre-match preparation. Their arcs conclude as steadfast supporters.

6. Who wins the rematch in Montreal?

The book does not say. The epilogue deliberately builds intrigue around the Montreal championship without revealing a result. The final line of the prologue-style section describes Mallory and Nolan smiling at each other across the board, leaving the outcome entirely for the reader to imagine.
