Editor’s note: Scafarelli’s question mark is perhaps out of place, but there is no doubt that 30. Kf1 would prevent the next irruption of the Black Queen on f2.
30. ... Be7 31. Rc1 Bxd5 32. Nxd5 Qf2! 33. Qf1 Qxg3 34. b5 Bxh4? (34. ... Qxh4+)
35. b6 Bg5 36. Rc2! Rb8 37. b7

37. ... Qh4+?
Editor’s note: Self-trapping the Queen, but, as two students of the Associazione Culturale “Il Delta della Luna” noted, the correct defence was by no means obvious, i.e, 37. ... Bd8!! (Niccolò & Riccardo), so as to reply to 38. Rc8? with 38. ... Qh4+! 39. Kg2 Rxb7 and it’s Black who wins!
38. Rh2 Qg3 39. Rh3 1–0.

Incredible, but possible

Professor Mauro Berni (Genoa, Italy) shared some pages from a booklet entitled Le mie 50 Siciliane by Francesco Scafarelli that combines history and not always happy endings.

Notes by Scafarelli, Le mie 50 Siciliane, Editrice Scacchistica Internazionale, Napoli, 1980, pp. 40-41 and pp. 49-50.

1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 Nc6 6. Bc4 Bd7 7. Be3 g6. Preferable is 7. ... Ng4 8. 0-0 or 8. Nxc6. It is more convenient for Black to submit himself to attack on the f-file by eliminating the e3-Bishop, than to deal with heterogeneous castling.
8. f3! Bg7 9. Qd2. Now White’s position is ideal for attacking on the Kingside.

9. ... Na5 10. Bb3 Nxb3. Or 10. ... Rc8 11. 0-0-0 Na5 12. h4 b5 13. Kb1 Nc4 14. Qe2 b5 15. Bg5 Nh7 16. Bc1 e5 17. Nf5 gxf5 18. Bxc4 Rxc4 19. Rxd6 Rc6 20. Rd3 Qc8 21. Rhd1 Be6 22. Rd8+ Qxd8 23. Rxd8+ Kxd8 24. Nd5 Kd7 25. Qe3 Bxd5 26. exd5 Rc7 27. Qd3 e4 28. fxe4 Re8 29. Qf3 fxe4 30. Qf5+ Kd8 31. Be3 Nf8 32. d6 Rb7 33. Qd5 Rb8 34. Qxf7 1–0 Pérez – Scafarelli, 2nd Costa del Sol Tournament, Torremolinos 1962.
11. axb3 h5. Preventing g2-g4.
12. h4 a6 13. 0-0-0 Rc8 14. Nd5 Nxd5. Questionable. More interesting is 14. ... Bc6.
15. exd5 0-0. Black cannot abstain himself from castling because of the e-file.
16. g4 Rc5? An oversight in a difficult position after that, as consequence of Black’s castling, the g2-g4 advance regained purpose.
17. Nc6! bxc6. Editor’s note: 17. ... Rxc6! 18. dxc6 Bxc6 seems most acceptable to Black.
18. Bxc5 cxd5. If 18. ... dxc5 19. dxc6!.
19. Be3 d4. Editor’s note: 19. ... hxg4! 20. h5! gxf3 21. hxg6 fxg6 22. Qxd5+ Rf7 23. Bh6 Qf8 24. Bxg7 Qxg7 25. Rd2 Bg4 26. Rdh2 Bh5 is the cold-blooded defence recommended by the mighty engines, but Scafarelli may well be excused for having been afraid of it.
20. Bxd4 Bxd4 21. Qxd4 Qa5 22. Kb1 Rc8 23. Rd3 Qc5. Black is again compelled to simplification.
24. Qxc5 Rxc5 25. Re1 hxg4 26. fxg4 Kf8 27. Rd4 Rc6 28. c4 e5 29. Rxe5? An unnecessary sacrifice.
29. ... dxe5 30. Rxd7 f5! 31. gxf5 gxf5 32. Kc2 Re6 33. c5 f4 34. Rd6! Re7 35. Rxa6 Kg7! 36. Kd2 e4 37. Ra1 Kf6 38. c6 Rc7 39. Rc1 Ke5 40. b4 Kd4 41. b3? (41. b5)
41. ... e3+ 42. Ke2 f3+ 43. Kxf3 Rf7+ 44. Ke2 Rf2+ 45. Ke1 Rg2? (45. ... Rh2!)
46. Rd1+ (46. Kf1!)
46. ... Ke4

Editor’s note: It goes without saying that the ending is an elementary book win for White after 47. Rd8, but...
47. c7?? Kf3 48. Kf1 e2+ 0–1. Incredible, but possible. This also is part of the charm of the game of chess.

Hello Goodbye Hello

Gate to the East

Vladimir Konstantinovich Bagirov – Roberto Cosulich
International Tournament; Naples, December 1977
Nimzo-Indian Defence E30

1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 4. Bg5. The Leningrad Variation, so named because it was in great favour among the players from that city, including also 10th World Chess Champion Boris Vasilievich Spassky.
4. ... h6 5. Bh4 c5 6. d5 Bxc3+ 7. bxc3 d6 8. Nf3 e5. Wikipedia’s popular assessment is open to question: “Black has achieved a Hübner Variation-like blockade, the difference being that White’s dark-squared Bishop is outside the Pawn chain. The pin on the f6-Knight is very annoying, and Black often breaks it by playing the drastic ... g7-g5, which also clamps down on a potential f2-f4 break by White. This move weakens Black’s Kingside, so rather than castle on that side, Black usually safeguards the King by playing ... Ke8-d8-c7”.
9. Nd2 Nbd7 10. e3 Nf8 11. Bd3 Qe7. If 11. ... Ng6 then 12. Bg3 0-0 13. 0-0 Ne7 14. f4! exf4 15. Rxf4 Ng6 16. Rxf6!? Qxf6 17. Ne4 Qd8 18. Nxd6 with enough compensation for the Exchange, Spassky – B. Larsen, USSR vs. Rest of the World, Belgrade 1970.

12. Qb1!? Quite a good idea — even though, years later, White would prefer to play 12. Bxf6! Qxf6 13. 0-0 Qe7! 14. Qc2 Nd7 15. f4 Nf6 16. Rae1 0-0 17. f5 a6 18. Ne4⩲ with a slight edge, Timman – Romanishin, 9th Interpolis Chess Tournament, Tilburg 1985.
12. ... g5 13. Bg3 Rg8 14. Bf5 Ng6 15. a4 Nh5 16. h3?! An unnecessary weakening of the Kingside. White ought either to exchange or retreat his light-squared Bishop, after which the Black King would have to decide whether to go West (... Ke8-d8-c7), or East (... Ke8-f8-g7-h8), with complex play and reciprocal chances in both cases.
16. ... Bxf5 17. Qxf5 Ng7 18. Qb1 f5 19. f3 0-0-0 20. Bf2 Rdf8 21. a5

The rush is on.
21. ... e4! A brilliant positional Pawn sacrifice which vacates the e5-square for the g6-Knight in preparation for a future attack.
22. fxe4 Ne5 23. 0-0? Castling into it. After this mistake, Black’s attack grows irresistible. 23. exf5! still offered White the means to escape the worst: a) 23. ... Nxf5 24. g4 Nf3+! 25. Ke2 (25. Nxf3? Nxe3! would be very bad for White) 25. ... N5d4+! 26. cxd4 Nxd2 27. Qd3 Ne4 (very harsh balanced); or b) 23. ... g4!? (who knows, maybe Cosulich would have played like this) 24. e4 Nxf5! 25. a6! b6 26. exf5 Nd3++ 27. Kf1 Nxf2 28. Kxf2 g3+ 29. Kf3 Qe5 30. Ne4 Rxf5+ 31. K~ Re8 regaining the piece with an easier game to play.

23. ... g4! 24. h4. 24. hxg4 is also answered by 24. ... Nh5! 25. gxh5 Qg5 26. g3 f4! 27. exf4 Rxf4 with a vehement attack.
24. ... Nh5. Threatening ... g4-g3 followed by ... Qe7xh4.
25. a6 b6 26. Be1. Not 26. g3 on account of 26. ... Nf3+ 27. Nxf3 gxf3 28. Kh2 Nxg3! 29. Bxg3 Rxg3! 30. Kxg3 Qg7+ 31. Kxf3 fxe4+ 32. Ke2 (if 32. Kxe4 then 32. ... Qg6+ followed by mate) 32. ... Qg2+ with mate in two.
26. ... g3 27. Rxf5 Qxh4 28. Nf1. White to play and selfmate in three moves: 28. Rxf8+?? Rxf8 29. Nf1? Qh1+! 30. Kxh1 Rxf1#. However, Bagirov can do little or nothing to prevent the final attack.
28. ... Rxf5 29. exf5 Nf6! The bells toll for His Majesty as Black is threatening ... Nf6-e4-f2.
30. Nxg3 Kc7! No illusion is left.
31. Qc2 Nfg4 32. Qe4 Qh2+ 33. Kf1 h5! 34. Ke2 Nf6 35. Qf4 h4 36. Ne4 Qxg2+ 37. Nf2 Rg4 38. Qh6 Ne4 39. Qh7+ Rg7 40. Qxg7+. Desperation, but 40. Qxh4 Qf3+ 41. Kf1 Ng3+ leads to mate in a few moves.
40. ... Qxg7 41. Nxe4 Qg4+ 0–1.

Alien Love

Four-time Women’s World Chess Champion and Peking University lecturer 侯逸凡 (Hóu Yìfán) x “Davos 2026: A World in Transition”: AI is not a competitor but a partner.

Human–AI partnership can solve global challenges 侯逸凡 (Hóu Yìfán), TIME, January 15, 2026 AI has revolutionized the game of chess, transforming how we play and think. Once a feared rival, AI is now an indispensable collaborator. I believe the most powerful force in chess today isn’t a human grandmaster or a supercomputer but the partnership between the two. Pairing human creativity and intuition with AI’s precision and analytical power can achieve results neither could accomplish alone. I’ve experienced the power of this partnership firsthand. During tournament preparation, AI tools often uncover patterns and possibilities I hadn’t considered. Yet, it’s my strategic intuition and understanding of the game’s psychology and nuance that determine which paths to pursue. This collaboration is about complementing each other’s strengths as much as it is about competition. The lessons from chess extend far beyond the board. Whether it’s addressing climate change, combating public health crises or reducing economic inequality, humanity faces challenges too complex for humans or machines to solve alone. By combining AI’s computational power with human empathy, adaptability and creativity, we can unlock solutions to the world’s most pressing problems. I see a future where humans and machines work together to solve challenges, not against each other. Partnerships that combine human ingenuity with AI’s capabilities could help to create a sustainable, inclusive future.

19th Chinese Chess League Division A Finals; Match 深圳鹏城队 (Shēnzhèn Péngchéng Team)–杭州银行队 (Hángzhōu Bank Team); time control: 90 minutes per 40 moves plus 30 minutes for the rest of the game plus 30 seconds per move starting on move 1; 绍兴 (Shàoxīng), January 13, 2026

French Defence C11

1. e4 e6 2. d4 d5 3. Nc3 Nf6 4. e5 Nfd7 5. f4 c5 6. Nf3 Nc6 7. Be3 cxd4 8. Nxd4 Qb6 9. a3 Bc5 10. Ncb5 a6 11. b4 axb5 12. bxc5 Qxc5 13. Qd3 Qe7 14. Nxb5 0-0 15.

Nb5 offering to repeat moves, but a draw wasn’t the result that 深圳鹏城队 (Shēnzhèn Péngchéng Team) wanted.
23. ... Rxa4 24. Nc7 Ra2

25. Qc1? Only this is the move that loses the game, although 侯逸凡 (Hóu Yìfán) can’t be blamed for not properly appreciating the consequences of 25. Qb3 Rb2 26. Nxd5!! Nxd5 27. Qxc4 Bb5 28. Qxd5 Bc6 29. Bxh7+ Kh8! 30. Qxc6 bxc6 31. Be4 with two very powerful Bishops for a Queen and an unclear situation. She chooses instead a more balanced approach (at least from a material standpoint), but only as long as her c7-Knight can survive...
25. ... Ra1 26. Qxa1. Forced, as both 26. Qc2 Rxe1 27. Rxe1 Ba4 and 26. Bb1 Raa2 lose material.
26. ... Rxa1 27. Rxa1 Qd6 28. Bxc4 dxc4 29. Na8 Nd5

That’s all, and it’s enough. White will soon pay the price for her “doomed” Knight.

Not All Chefs are Cooks

Again on cooks and politics

Giorgio Agamben, Quodlibet, January 8, 2026

It is well to reflect on the phrase attributed to Lenin — though he apparently never uttered it — according to which “every cook can and must learn to govern the state”. Hannah Arendt, commenting the pseudo-Leninist sentence, wrote that in a classless society, “administration would be so simple that any cook could take charge of it”. Lucio Magri rightly observed years later that Lenin’s phrase should be reversed, so as to mean that “state can be run by a cook only insofar as there are no longer any cooks”.
In the only passage where a cook appears in his writings, Lenin actually says something different and differently well developed. “We are not utopians”, he wrote in a 1917 article. “We know that a cook or an unskilled labourer cannot immediately get on with the job of State administration. In this we agree with the Kadets, Breshkovskaia, and Tsereteli. We differ, however, from these citizens in that we demand an immediate break with the prejudiced view that only the rich, or officials chosen from rich families, are capable of administering the state, and carrying on the routine, everyday work of government. We demand that instruction in matters of governing the state be carried out by conscientious workers and soldiers and that this begin at once, i.e., that all working people and all the poor begin promptly to be given access to this instruction”.
As Lenin’s words suggest, the paradigm hidden behind the utopian government of the cook is that of the administrative state, according to which, once the domination of capitalim is eliminated, politics would give way, as Engels also reiterates, to the simple “administration of things”. Or, if you prefer, politics would present itself in the form of the “police”, which, starting with the theorists of police science in the 18th century, is the term which translates the Greek politeia. “Police” we still read in Marcello Adriani’s translation of Plutarch, published at Florence in 1819, “it means the order and arrangement of a city by which its affairs are organised; and so it is said there are three polizie (sorts of government): monarchy, oligarchy, and democracy”.
This is the paradigm of the admnistrative State theorised by Sunstein and Vermeule, which is now imposing itself in advanced industrial societies, where the state seems to be resolved into administration and government, and “politics” to be turned entirely into “police”. It is significant that, just in a state conceived in this sense as a “police state”, the term ends up designating the least edifying aspect of government, i.e., the bodies bound to ultimately ensure, by force, the realisation of the state’s governmental vocation. What we see today with brutal clarity is, in fact, that this very seemingly neutral state, which claims to pursue only the good order of things and mankind, can reveal itself just because of this to be devoid of any kind of limit in its action. The cook is today the quintessential figure of the tyrant.
Politics can never exhaust itself in mere administration, even in the form of good government that inevitably degenerates into bad government. Because it coincides with the free life of human beings, politics is essentially ungovernable and unmanageable. This is why Lorenzetti’s fresco in Siena, so-called of Good Government, depicts dancing maidens in the foreground. “Good government” is no government at all.

The Doom Loop

The mistery of power

Giorgio Agamben, Quodlibet, January 7, 2025

Paul’s Second Epistle to the Thessalonians can be read as a prophecy about the current situation in the West. The apostle evokes here “a mistery of anomie”, of “lawlessness”, which is underway, but which will not be fulfilled with the Second Coming of Jesus Christ unless there first appears “the man of lawlessness (ho anthropos tes anomias), the son of perdition, who opposes and exalts himself against every so-called god or object of worship, so that he takes his seat in the temple of God, proclaiming himself to be God”. There is, however, a power which restrains this revelation (Paul simply calls it, without further defining it, “a restrainer — katechon”). This power must therefore be wiped off, for only then “will the impius (anomos, lit. “the lawless”) be revelead, and the Lord Jesus will slay him with the breath of his mouth and destroy him by his coming appearance”.
The theological-political tradition has identified this “power which restrains” with the Roman Empire (as in Jerome and, later, in Carl Schmitt) or with the Church itself (in Ticonius and Augustine). It is evident, in any case, that the power which restrains identifies itself with the institutions which sustain and govern human societies. For this reason, their elimination coincides with the advent of the anomos, a “lawless man” who takes the place of God and “with signs and false wonders” leads to perdition “those who rejected the love of the truth”.
It is possible to see in the mystery of anomie not so much a supratemporal enigma, whose sole sense is that of putting an end to the history, but rather a historical drama (mysterion in Greek means “dramatic action”), which corresponds perfectly to what we are living out today.
Dominant institutions seem to have lost their sense and are literally disappearing, giving way to an anomie, a lawlessness that claims to be legal, so to speak, but that in fact has abdicated all legitimacy. The State (the principle which restrains) and the “lawless” are actually two sides of the same mystery: the mystery of power. As the United States are now unscrupulously showing, the “man of anomie”, the “lawless” designates the figure of state power which, dropping the constitutional and ethical principles that traditionally limited it and, with them, “the love of the truth”, relies on the “signs and false wonders” of weapons and technology. It is this confusion of anarchy and legality in a now-permanent state of exception that we must unmask and make inoperative in any areas.

Up Close & Personal

Conversation with Sonja Graf

Francesc Armengol i Burguès, La Rambla, February 11, 1936, p. 5

My friend Koltanowski had the good sense to introduce me to Miss Sonja Graf, the German Women’s Champion, who has been in Barcelona for a few days.
I took advantage of the opportunity to ask her for a conversation for La Rambla chess column, which she readily agreed to, and which took place last Tuesday at the Granja Royal, after enjoying a delightful concert given by the Toldrà sextet. Koltanowski, who acted as my interpreter, was a witness to our talk:
— Did you like this tune, Miss Sonja?
— Oh! Charming — she answered me in a strict German and masculine accent, shaking a fist on the table, where there was a small cardboard box, while trying to sing some notes of the zarzuela La del manojo de rosas.
— What is your impression of our country?
— Wonderful. I met always nice people so far. Take note of the names of some of them: Domènech, Cabestany, Calduc, Cardona...
— May I be indiscreet in my questions? It is so strange and unusual that foreigners come to visit us...
— I never hesitate. I am at your command.
— What purposes brought you here?
— To personally get to know your chess community, of which I have great references, as well as to introduce myself to all Catalan fans; and, least but not last, to train with Koltanowski, since I will participate in the Margate and Semmering tournaments.
— When will the Margate tournament start?
— On April 15. Pray note that in the Margate tournament it is very likely that Glòria Velat, Sofia Ruiz and Montserrat Puigcercós will participate in the women’s tournament, and Cabestany, Calduch, Cardona, Domènech and Solà in the men’s tournament.
— And the Semmering one?
— On June 16. It’s noteworthy that only women will play the Semmering tournament. One guest per country. I am currently dealing with the admission of a competitor from your country. I assume that the Grand Hotel Panhans, the organiser of this event, has already received my recommendation.
— Are there significant prizes at stake?
— 200, 150, 100 and 75 dollars, respectively, will be awarded for the first four places. An amount for each won game. As mandatory compensation, second-class travel and accommodation will be paid.
— Miss Graf, may I ask you how old you are?
— Let’s talk chess...
— I ask how old you are because a young lady shouldn’t always be talking chess...
— Well... in Ireland they say I’m twenty-one; in England they say I’m twenty-two. So now it’s up to you to make a choice...
— Since we’re talking about years... When did you begin to play chess?
— I’ve been playing it for like five years.
— Do you remember any brilliant performance?
— You may note that last year I took part in the Margate and Yarmouth tournaments. In the first, which involved several competitors and was held in two stages due to the Preliminaries, I finished third in the Final A. And in the second, which involved twelve competitors, I have the honour of defeating Prins and Klein.
— Do you think you are a good simultaneous player?
— I remember I gave five exhibitions in Ireland. In total, 79 games, twenty-seven draws and ten losses.
— Can you tell me if you are planning to get married?
— Let’s talk chess...
— At least, will you tell me where you were born?
— In Munich.
— And who was your first teacher?
— Dr. Tarrasch.
— His influence would have an effect on some competition...
— It may be noted that in the Vienna tournament of 1933, which was held in a double round-robin format, seven women participated and I took first place.
— In which section did you compete in the Hastings tournaments of 1934/35 and 1935/36?
— In the Major A, Section 1, and Premier Reserves B respectively.
— Would you like a cigarette?
— With pleasure.
— Which technique do you prefer, that of Euwe or Alekhine?
— That of the former World Champion.
— Your favourite player?
— Spielmann.
— Do you think it is good for women to play chess?
— Of course, since I am adept at it... But should be noted that, in general, women are not predisposed to it.
— Would you mind if I say that you remind me of Lilienthal? Your cropped hair, your bearing...
— If you think so, okay; I have no objection to it.
— Can you provide me with a photograph for the sake of the readers of La Rambla?
— Here it is, along with a game that I really like.

(a) Castling was not good because of ... g7-g5.
(b) 12. Nd5 c6 13. Nxf6+ Qxf6 looked good.
(c) It is obvious that White is hoping to get to d3-d4 right away, but has not taken the e-file into account. Sonja Graf is here in her element!
(d) If 16. d4 there naturally follows 16. ... bxc3!.
(e) 18. Nxc3 Bb4 19. Rcl d5! deserved consideration [Translator’s note: Armengol overlooked 19. ... Nd5! which would win on the spot].
(f) Dangerous tripled Pawns!
(g) If 19. Nxc3 there follows 19. ... Qd4 20. Rc1 c4!.
(h) At first glance White regains the Pawn with a good game. But Miss Graf wins the game with a splendid combination.
(i) The decisive move, which wins the Queen and the game. What if now 22. exd5? Here comes the pointe of the combination, since after 22. exd5 Rxe3+! 23. fxe3 Qxe3+ 24. Kd1 Rb2! 25. Re1! apparently it is White who will win and not Black. But there follows 25. ... Qd2+!! 26. Qxd2 Rxd2#!! — a treacherous blow which tears through the darkness.

Conversa amb Sonja Graf

Professor Mauro Berni (Genoa, Italy) shared with me the reading of the Catalan newspaper La Rambla of Tuesday, February 11 1936, p. 5, where its chess columnist, Francesc Armengol i Burguès, conducted a lengthy and personal interview with Sonja Graf.

40. Nxa6! Kd7? A dramatic faux pas. Cosulich overlooks 40. ... Kd8! (instead of 40. ... Kd7?); there might follow 41. b5 (otherwise the Knight is trapped) 41. ... Bxb5 42. Nb4 Ke7 (or any other move with the King) leaving White with a meaningless extra Pawn and a draw in sight.
41. c6+! Kxc6. “The Knight is free, for 41. ... Bxc6 42. Nb8+ and Nb8xc6 yields White an easily winning Pawn endgame”.
If 41. ... Kc8 then 42. Nc5 Bxc6 43. Ne6 winning easily.
42. Nc5 1–0. If 42. ... Bb5 then 43. Ne6 and it is over for Black.
