Man on a Raft

When he could, Roberto Cosulich preferred to live where there were seas and ports. And when there was no sea, he would be content with a river. And so, on his way from the Chilean sea to the Mediterranean, he docked his raft on the English shores in 1965.
With the precious help of John Saunders, we succeeded in spotting him here and there around the British docks:

9th Easter Congress — Major A

16th Ilford Whitsun Congress — Premier Reserves A
Ilford, June 4–7, 1965
As we read on the BritBase website, “The final scores were: (1) Raymond D. Keene 3½; (2) T. Goodhill 3; (3-4) Kenneth W. Lloyd, George W. Wheeler 2½; (5) Andrew J. Whiteley 2; (6) Roberto Cosulich (Santiago, Chile) 1½”.
Even in this case none of his games are given.

Furthermore, a few references to Cosulich playing board seven for Middlesex in the 1964/65 Southern Counties Championship appear on The Monthly News Bulletin of the Southern Counties Chess Union, No. 46, Volume 7, June 1965. Cosulich, with White, first defeated John G. Brogden of Surrey, and then David G. Levens of Leicestershire, leading Middlesex to the Semi-Final match against Chesire which took place on June 12, 1965. “Some of the players on higher boards were well-known (Wade, Hartston, etc.)”, Saunders writes. “He drew his game (playing Black) with Vernon Dilworth. Middlesex qualified for the final but he did not play in that match, so perhaps he left the country at that point”.
It should be noted that the distinguished English amateur Vernon Dilworth was not only the originator of the homonymous variation in the Open Ruy López (1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6 5. 0-0 Nxe4 6. d4 b5 7. Bb3 d5 8. dxe5 Be6 9. c3 Bc5 10. Nbd2 0-0 11. Bc2 Nxf2), but also the proponent of a controversial gambit in the Nimzo-Indian (1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 4. e4).

What Was Left

Pál Charles Benkö – Roberto Cosulich
11th International Tournament; Venice, November 1974
English Opening A29

Notes by Grandmaster Pál Charles Benkö, Chess Life & Review, Vol. XXX, No. 2, February 1975, pp. 81-82, and The Chess Player, No. 7/1974, 883, p. 220.

I had to play Cosulich in the last round, and whether or not he would make the IM norm depended on this game. But for me it was the last chance to improve my standing after my bad luck the previous day.
1. c4 e5 2. g3 Nf6 3. Bg2 Nc6?! (3. ... c6!?)
4. Nf3! White deliberately delays Nb1-c3, since then Black could play ... Bf8-b4 adopting a very popular line today which my opponent played in this tournament. Also, my game with Malich (Skopje 1972) followed that line, which I analyzed in CL&R.
4. ... Bc5 5. 0-0 (5. Nxe5?!)
5. ... 0-0 6. Nc3 d6 7. d3 Bd7 8. e3⩲ Bb4?!


Obviously, Black has not achieved what he wanted with his ... Bf8-c5, so he tries to get back in known lines.
9. Ne2!? Not much advantage was promised by 9. Nd5, e.g. 9. ... Nxd5 10. cxd5 Ne7 and 11. Qb3 to capture the QNP is not recommended.
Also possible was the simple 9. Bd2, but the text move is psychologically better motivated, as Black will have trouble with his KB later.
9. ... e4?! Trying to secure the position of his KB, but now the center is opened advantageously for White.
10. dxe4 Nxe4 11. Qc2 Re8 (11. ... Bf5? 12. Nh4)
12. a3 Bc5 13. b4 Bb6 14. Bb2±


14. ... Qe7?! (14. ... Nxf2!? 15. Kxf2!?)
Black already stands badly since the position of his Knight on e4 is far from secure. On 14. ... Bf5 White could answer 15. Nh4. If the Knight moves away, c4-c5 is menacing. Perhaps Black should have considered 14. ... Nxf2, although White’s two minor piece may prove stronger than Black’s Rook. Even capturing with the King is to be considered after 14. ... Nxf2.
15. Nf4! Black’s Queen does not stand well on e7 because of the weakness of his d5, which explains the following blunder. Black’s entire setup does not meet the demands of the position. Now if 15. ... Nxf2 16. Nd5 wins.
15. ... Nf6? (15. ... f5)
Now Black’s game collapses but his situation was not hopeful anyway.
16. Ng5!+−


Decisively strong, leaving Black no way out. On 16. ... g6, defending against the threats to his h7, 17. Bd5 would have been very strong, e.g. 17. ... Nxd5 18. Nxd5 Qxg5 19. Nf6+ and Black’s Queen is lost. Moreover, on 17. ... Nd8 or 17. ... Rf8 protecting the weak f7, 18. Nxg6 would win easily.
16. ... Ne5 17. Nd5 1–0. After 17. Nd5 Qd8 18. Bxe5 Rxe5 19. Nxf6+ Qxf6 20. Qxh7+ Kf8 21. Qh8+ White will be ahead the Exchange and two Pawns.

Monte Cristo

With the exception of the two Olympiads in which he competed, Roberto Cosulich rarely played outside of Italy. One of these times was when he tore up an invitation to Tunisia.

“The 6th International Tournament in Tunis, to which an Italian Master is invited every year, was narrowly won by the Dutch International Master Ree, the only undefeated player.
Tied at second place were Austrian Grandmaster Robatsch and Master Cosulich. The defeat suffered by our representative in the direct clash with Robatsch prevented him from winning the tournament”.

L’Italia Scacchistica, No. 5, May 1972, p. 113.

Roberto Cosulich – Slim Bouaziz
6th International Tournament; Tunis, December 1971

1. e4 c5 2. Nf3 d6 3. Bb5 Nc6 4. Bxc6 bxc6 5. 0-0 e6 6. e5! d5 7. d3 Ne7 8. c4 Qc7. If 8. ... Ng6 then 9. Nc3 Be7 10. b3 0-0 11. Na4!⩲ Cosulich – Paoli, 13th New Year’s International Tournament, Reggio Emilia 1971.

18. Nf5?! A tempting but unsound sacrifice, although at first glance White’s storming attack may seem doomed to success. More systematic is 18. a3 (so as to prevent ... Rb8-b4 and also preparing for b2-b4) 18. ... 0-0 19. f4 leaving White with a clear superiority on both wings.
18. ... exf5 19. e6 f4 20. exd7 Kd8 21. Rxe7. If you say a you must say b.
21. ... Kxe7 22. Bh4 f6. Clearly not 22. ... Kxd7? because of 23. Qg4+ Ke8 24. Qxg7 with too many threats.
23. Qg4


23. ... Kf8? Probably Cosulich was expecting 23. ... Kf7 when 24. Re1 Bd3! gives White hardly anything more than a draw by perpetual check after 25. Qe6+ Kg6 26. Qg4+. But both he and Bouaziz overlooked here the way of coming out of the storm, say 23. ... Qe5!! 24. Qxg7+ Ke6 when White is left with a handful of flies.
24. Re1 Rd8


25. Bxf6! A devastating blow. Bouaziz was still hoping for 25. Re7? Kxe7 26. Qxg7+ Ke6 27. Qxf6+ Kxd7 28. Qf5+ Ke8 29. Qe6+ Kf8 with a draw by perpetual check. The rest is a foregone conclusion.
25. ... gxf6. Neither 25. ... Qxd7 26. Qg5!! nor 25. ... Rxd7 26. Qe6 Qc8 27. Be7+ Ke8 28. Qe5! saves Black.
26. Qe6 Kg7 27. Qg4 Kf8 (27. ... Kh6 28. Re7+−)
28. Qf5 Kf7 (28. ... Qxd7 29. Qxf6+ Kg8 30. Re7+−)
29. Qh5 Kf8 30. Re8 Kg7 31. Re7 1–0.

Trip trap

Roberto Cosulich – Francesco Scafarelli
7th Italian Team Chess Championship; Monticelli Terme, April 1966
Sicilian Defence B56

Notes and punctuation by International Master Francesco Scafarelli, Le mie 50 Siciliane, Editrice Scacchistica Internazionale, Napoli, 1980, p. 50.

1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 d6 6. Be3 e5 7. Ndb5 a6 8. Na3 Ng4 9. Nc4! Nxe3 10. Nxe3 Be7 11. Ncd5 Be6 12. c3! 0-0 13. h4 h6 14. g3 b5 15. Bd3 Rb8 16. b4 Re8 17.

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.

Roberto Cosulich – Francesco Scafarelli
8th Italian Team Chess Championship; Recoaro Terme, May 1967
Sicilian Defence B75

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.

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.
