4. 0-0 Nxe4 5. d4 Nd6 6. Bxc6 dxc6 7. dxe5 Nf5 8. Qxd8+ Kxd8. A critical tabiya position, with pros and cons for both colours. White’s Kingside Pawn majority should be compensated by Black’s Bishop pair, while the loss of the right to castle is of hardly any importance to Black, as the position after the exchange of Queens can be regarded already as an endgame.
9. Bf4!? Be6. It may be worth noting that here 9. ... h6 10. Rd1+ Ke8 11. Nc3 Be6 was preferred by the “king of draws” in L. Horwitz – Schlechter, Vienna Chess Society Winter 1895/96 Tournament, Vienna 1896.

Lost & Not Found

For the sake of completeness, it is important to add that the ghost of Roberto Cosulich was still haunting Genoa in 1978. Indeed, according to Scaccomatto (No. 6/1997) — the monthly newsletter of the Circolo Scacchistico Genovese Luigi Centurini — he would come back from India and leave days later to Latin America “one autumn evening in 1978, after dropping by the Club to say hello to his friends”. The tale continues thus:

“The valuable account provided by Mario Quaglia here comes to our aid. On the way back from India, Cosulich calls in at Genoa, now clean-shaven, well dressed, with short haircut (!). He tells about his wanderings through India, where he would earn his living by playing blitz chess (he was very good even in this specialty, with several Italian Championsip titles under his belt). He stayed here for some days, then he left again. His restless, unhappy mind pushes him towards another destination: he goes back to South America. Roberto Cosulich never came back from this trip. A few years ago we learned from a French chess magazine that the passport of someone called Cosulich, a chess Master, would have been discovered in Peru among the victims of a natural disaster. His body, however, was never found”.

The name of Mario Quaglia is not new since it was mentioned by Paolo Silvestri in a biographical article which appeared on the SoloScacchi website on January 4, 2014: “Halfway between 1973 and 1974 Roberto used to hang out with a group of — let’s call them thus — Genoese creatives: Mario Quaglia, Popi Frizziero, Umberto Melli... I remember them in a small flat at Boccadasse... discussions... chatter... laughter... focaccia and white wine until three in the morning”.
And so, a friend of Cosulich put another period to what everyone knew or guessed. In Quaglia’s account, however, there is a detail that sounds implausibly novelistic. I’ve been in India many years ago, and would doubt seriously that, at the time (1978), anyone could in any way earn a living by playing blitz chess. Why? Simple. There weren’t any opponents as chess was not popular at all in India, however incredible it may seem nowadays! Secondly, more importantly and surely Cosulich hadn’t gone to India to play chess. He was escaping a life he abhorred, where chess was mere routine work. And now, would he have played chess for a handful of rupees? No, never again. Most likely he hid in an ashram, where studied meditation and Eastern philosophy, and learned all secrets of reincarnation. It is not given to know whether, in his self-deconstruction, he changed his name, too. But of course it’s not impossible.
In the meantime, life went on.
There were birthdays and funerals he missed. Conversations and encounters he wasn’t part of.
His ancient mentor, Hermann Pilnik, died on November 12, 1981, at Caracas, Venezuela.
Giambattista Lazagna was acquitted and discharged from any prosecutions, indictments and imprisonments commenced against him.
The late Roberto Cosulich no longer needed his passport.

Bye and fly away

In a long article entitled “Cosulich, un ‘giallo’ ancora senza soluzione” (“Cosulich, a ‘detective story’ still without a solution“), by Marco Esposito and Sergio Pagano, Scacchitalia, No. 3, October 2026, pp. 40-43, the cronistas collected the testimonies of a national chess umpire, Lorenzo De Angelis, who would have met Roberto Cosulich in Genoa, Italy, in 1985, five years after his alleged passing. They would have also played a few off-hand games — all won, of course, by the bearded fakir. But when it comes to Cosulich, any rumours of his death, as well as of his resurrection, are usually much exaggerated, and De Angelis himself jokes about it a little bit: “I played against a ghost”. Esposito and Pagano also questioned Genoa Municipality’s Registry Office, according to which in 1977 Cosulich moved from Via Stefano Prasca in Quarto dei Mille district to Vico del Cioccolatte in Carmine district, where — at least officially — he resided until February 17, 1986, when he was cancelled from the Registry.
This is all suggestive, to say the least, but where one resides is not necessarily where one lives. As a matter of fact, Cosulich was seen for the last time in his mortal flesh at the Fiumicino Airport, Saturday, 10, or Sunday, 11 June 1978, on his way to India, and, like Kowalski, disappeared through the Vanishing Point into the world.

Flashbacks of a Flower Child

While watching the game between these two giants, I often met Cosulich’s gaze — a very intelligent and tense one, given the no-holds-barred nature of the game, like an obstacle race in which the palm is awarded to the “one who comes first and first delivers checkmate”. I will never forget Cosulich’s gaze, addressed at a child like me, who likely grasped only a few marginal details of the game.

Odds and Sods

General elections or opinion polls?

Giorgio Agamben, Quodlibet, November 2, 2026

The fact that what we continue to call democracy has lost its significace is proven by the indiscriminate use of opinion polls, which lay bare the now obvious conclusion that elections are mere opinion surveys and not the expression of a political will. By showing the numerical weight of parties on a daily basis — through the changing views of survey respondents — such polls produce a sort of perpetual election, which no one controls and can therefore be manipulated — as indeed it is — so as to influence, on its part, the very opinion that it should reflect. We call democracy a government by public opinion, i.e., something without any political substance, which has no other reality than that of polls that, at the very moment they seem to record it, incessantly create it, alter it, and manipulate it. The process by which Rousseau’s “general will” — which cannot be numbered — got transformed into public opinion — which is only a matter of numbers — defines the fate of Western democracies.

Time Reborn

Neolithic conservative

Giorgio Agamben, Quodlibet, October 30, 2026

Paul Goodman, one of the most radical anarchist thinkers of the twentieth century, once defined himself as a “neolithic conservative”. And Ivan Illich — who thought of himself as one who was standing with one foot in the Catholic tradition and the other in the mire of his own time — used to say that his orthodoxy was so ancient and complete as to be revolutionary. This means that to comprehend, and perhaps even dismantle, the historical time in which we live, one must keep a foot in prehistory. This situation on the threshold or boundary between two incommensurable epochs is precisely what our time proves unable to satisfy. Not only does our time think in one dimension only, but has lost any relation with its own past — a relation without which no access to the present is possible. For this reason it can only look to a future which is in reality nothing else than the consequence of a past to which it is entirely oblivious — and which moves it with its strings like a puppet. Only those who stand firmly on both legs between past and present can reckon with both of them without being unconsciously moved by them. Only a neolithic conservative can be revolutionary enough to open up a new space for thought and action.

Comments in quotation marks by L’Italia Scacchistica, No. 8, August 1967, pp. 184-185. The commentary is unsigned but is probably the work of the magazine’s editor-in-chief, Giovanni Ferrantes.

1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 g6 5. c4 Bg7 6. Be3 Nf6 7. Nc3 Ng4. Gyula Breyer’s brand.
8. Qxg4 Nxd4 9. Qd1 Ne6. Aron Nimzowitsch’s trademark.
10. Qd2 d6 11. h4!? At the time a novelty, which was probably inspired to Mariotti by his early mentor, the exiled Russian Prince Nikolay Alekseyevich Obolensky, who, long before the coming of AlphaZero, did not fear to use the h-Pawn as an attacking weapon — with both White and Black.
11. ... h5 12. Be2 Bd7 13. f4 Bc6. L’Italia Scacchistica attaches a question mark to it, but maybe it is not so bad as they think. Nevertheless, 13. ... Qa5! 14. Rc1 Nc5⇄ was certainly best now.
14. f5 Nc5 15. Bd4. “Now Black finds himself in a very critical situation”.
15. ... Bh6 16. Qc2

16. ... Rg8? So far, this is Black’s only mistake, and alas for him — is an almost definitive one. Much better was 16. ... e5! 17. Bxc5 (17. fxe6 0-0! leads nowhere for White) 17. ... dxc5 18. Rd1 Qf6 19. Nd5 Bxd5 20. Rxd5⩲ leaving White with little or nothing of advantage.
17. b4. “Wins a piece. Now Black must seek for the most counterplay possible in the attempt to save the game”.
17. ... Nxe4!? 18. Nxe4 gxf5 19. Ng5 e5 20. Be3. Not 20. Nxf7? Kxf7 21. Qxf5+ on account of 21. ... Kg7! 22. Bf2 Rf8 with the upper hand for Black.
20. ... Bxg2. “If now 20. ... f4? 21. Qh7!”.
21. Qxf5 Bxg5 22. Bxg5 Rxg5 23. hxg5 Bxh1. At the end of the skirmish, Black is two Pawns up — but only temporarily.

24. 0-0-0! Here is the point. If now 24. ... Bc6 there would follow 25. g6! winning at once. Therefore Black’s reply is forced.
24. ... Be4! 25. Qxe4 Qxg5+ 26. Kb2 0-0-0. Black has three Pawns for the Bishop and his King is castled, but only straight into the enemy’s attack!
27. Bf3 Rd7 28. Qh7? Mariotti complicates life uselessly. More straightforward was 28. c5! f5 29. Qc4 e4 30. cxd6+ Kb8 (30. ... Kd8 31. Bxh5!+−) 31. Qe6+− with an easy win.
28. ... h4 29. Be4 Kc7 30. Bf5. Probably White had to think about exchanging Queens on f5, but who can blame him for not doing so?
30. ... Re7 31. Bh3. “Threatens 32. Qh8 f5 33. Qf8 and wins”.

31. ... e4! “The only move”.
The way in which Cosulich saves the ending is remarkable, and remarkably technical. The punctuation of the following moves is that of the original text from L’Italia Scacchistica.
32. Qh8 Qe5+ 33. Qxe5 Rxe5 34. Re1. “If 34. Rf1 Black intended to reply with 34. ... b5! exchanging as many Pawns as possible”.
34. ... f5 35. Kc3 f4 36. Kd4 e3 37. Bg2 Rg5 38. Bf3 b5! 39. Rh1 bxc4 40. Rxh4 Re5! 41. Rh2! “It was a draw with 41. Rh1 on account of 41. ... e2! 42. Re1 Re3! 43. Bxe2 c3 and White can no longer move anything".
41. ... a5! 42. a3 axb4 43. axb4 Rg5 44. Rh4 Re5 45. Rh2 Rg5 46. Ke4? “This move leads to a draw by force. The only try was 46. Rh7+ Kb6! 47. Kxc4 d5+! (to close the f3-Bishop) 48. Kd4 (if 48. Bxd5? Rxd5! and Black queens) 48. ... Rf5! [sic] and it is problematic for White to win”.
Oh, no! The last move of the analysis is totally wrong, as after 48. ... Rf5?? 49. Rh6+! Kb5 (49. ... Kc7 50.b5+−) 50. Kc3 the Black King is caught in a mating net.
Therefore after 46. Rh7+ Kb6 47. Kxc4 d5+! 48. Kd4 Black has to look for 48. ... Rg3! 49. Bxd5 e2 50. Rb7+ Ka6 51. Re7 Kb5!= with a draw soon (but not 51. ... f3?? because of 52. Kc5!+− with unaivodable mate).
46. ... Rb5 47. Kxf4 Rxb4 48. Kxe3 Rb3+ 49. Ke4 d5+ ½–½. “The last three moves were made by inertia”.

Short on Time

“Short on time, White won after a long skirmish; he could, however, mate in three moves”, Grandmaster honoris Caïssa Enrico Paoli writes in his book L’arte della combinazione scacchistica, U. Mursia editore, Milano, 1986, p. 136. The proffered solution (Ibid., p. 143) is 1. Qh3+ Kg8 2. Qh8+!! Bxh8 3. Nh6#. However, it should be noted that after 1. ... Bh6 2. Qxh6+ Kg8 3. Qxg6+ Qg7 4. Nh6+ Kh8 5. Qxg7# it takes five moves for White to mate.

The Incommensurable Multitudes of the Being

The unnumberable people

Giorgio Agamben, Quodlibet, October 23, 2026

One of the fundamental political problems — if not the most urgent one — is how to think of a not-numberable multiplicity (or multitude). As a political concept, the people only makes sense on the condition that it cannot be numberable; if it can be counted, what becomes decisive is no longer the people as such, but rather a numerical quantity — the so-called majority — into which the people dissolves through the perverse device of elections or plebiscites. The people — as well as the human species — is not a whole constituted by numberable singularities: the “popular” or “generic” character — i.e., the political character — must fully belong to the individual as such. It is what Marx sought to think through the concept of Gattungswesen (“species-being”), which defines each human being and not a numberable quantity. Since every human being “relates to himself as to the present, living species”, this cannot be a numerical sum of individuals, but it is a reality which is essentially and completely present in each one. If the people, like the species-being, gets numbered, it divides not only into a majority and minority, but also into factions, among which civil war necessarily arises. In Leviathan, Hobbes attempted to unravel this aporia by hypothesising a numberable multitude — which he calls multitudo disunita (disunited mutitude) — that constitutes itself as a unity into the body of the sovereign; but this means that the people has no unity other than by abolishing itself into the artificial person of the sovereign.
How to think, then, of a not-numberable multitude? Popularity and politicality are not definable properties, which, like the racial unity for the Nazis, can be attributed to any individual. Rather, they arise from the absence of a common identity element, which determines its belonging to this or that whole, to this or that class, and thereby renders it numberable. Like the proletariat according to Marx, the people cannot coincide with itself: it is, by its own constitution, non-all. If one attempts to seize it as a non-all, it resists any definition — and this resistance, this unnumberable rest is the people; it is the genuine political element.
