10. Bc2 b5 11. Nf1. 11. b3 Nb6 12. bxc4 Nxc4 13. Nxc4 bxc4 14. h4!? also gives White a strong inititative, Ghizdavu – Padevsky, 20th Chess Olympiad, Skopje 1972.
11. ... Bb7. 11. ... Nb6 eventually yielded Black a draw, but most by virtue of his higher rating: 12. h3 Bd7 13. N3h2 h5 14. f4 Qc7 15. Nf3 0-0-0 16. Be3 Kb7 17. Bf2 Ra8 18. Bh4 a5 19. Bxe7 Nxe7 20. Ng5 Raf8 21. Qf3 f6 22. exf6 Rxf6 ½ : ½ Wessendorf – Eingorn, 11th OIBM Open, Bad Wiessee 2007.


12. h3! 侯逸凡 (Hóu Yìfán) plays quietly and strongly. Many years earlier, a game from the British Chess Championship continued 12. b3 Nb6 13. Ng3 Kd7 14. Rb1 h5 15. bxc4 Nxc4 16. Nd2 Nxd2 17.

Rxe6 Rxe6 34. Bxf5 Rge8 35. Rxe6 1 : 0 Crawley – Lund, 75th British Chess Championship, Blackpool 1988. Furthermore, 12. h4!? was also interesting, since after 12. ... Bxh4 13. Nxh4 Qxh4 14. Re3 White’s attack more than compensates for the Pawn.
12. ... h6 13. N3h2 Qb6 14. Qh5. 14. Qg4!? is almost a “dual”, possibly transposing to the game.
14. ... g6?! That is an irresistible invitation for the White Bishop to immolate itself, but Black has no particularly better way to go. 14. ... 0-0?? 15. Bxh6! is simply disastrous, whilst after 14. ... b4 15. f4 Nf8 16. f5 White comes first anyway.


15. Bxg6! fxg6 16. Qxg6+ Kd8 17. Qxe6.


White has three Pawns for the Bishop, plus the Black King at the mercy of her attack. 侯逸凡 (Hóu Yìfán) does not need anything more.

Random Thoughts

One of the earliest versions of random chess was mentioned in an old book titled “Miscellanea sul Giuoco degli Scacchi”, E. Carlo Usigli, Naples, 1861:

rnqbbknr/p1pppp1p/1p4p1/8/8/1P4P1/P1PPPP1P/RNQBBKNR w - - 0 1

Mutatis mutandis, the position in the diagram is identical to the position number 521 of chess960, if not for the -b and -g Pawns already advanced one square and the apparent non-faculty of castling. Let’s quote from page 607:

The pieces randomly set up. Game played between General van der Hoeven [White] and Alexandre [Black] (1).
1. Qb2 f6 2. d3 Nh6 3. e4 Nf7 4. Bf3 c6 5. Bc3 Kg7 6. Nd2 d6 7. Ne2 Rf8 8. h4 h5 9. Rd1 Nh6 10. Nc4 b5 11. Ne3 e5 12. d4 Bc7 13. Bg2 Bd7 14. Rd3 a5 15. Ke1 b4 16. Bd2 c5 17. d5 a4 18. Nc4 a3 19. Bxh6+ Kxh6 20. Qc1+ Kg7 21. c3 Na6


22. Nd2 bxc3 23. Nxc3 Nb4 24. Re3 f5 25. f3 f4−+
(1) The General, fearing his opponent as being much stronger than him in the knowledge of openings, proposed him to draw the starting array, which had to be the same for both colours. Thus the following position resulted: Rooks and the Knights at their own squares, Bishops at e1 (e8) and d1 (d8), King at f1 (f8), Queen at c1 (c8); Pawns at their own squares except for the b- and -g Pawns being advanced one square.

III Fischerandom Kaos

Notevole affluenza di partecipanti e di pubblico alla III edizione del Fischerandom Kaos! Tetragoni alle dritte di taluni autorevoli counsellori abbiamo riproposto la nostra consueta formula: niente egide ingombranti né coercitive sovrintendenze, ma spazio aperto alla creatività. E così si è svolta la simultanea di scacchi960 tenuta dal Maestro Internazionale Vangjel Buli – sempre amabile, professionale e disponibile – seguita da una rassegna di balletti coreografati da sei giovani danzatrici (in ordine di apparizione: Letizia, Serena, Alessia & Elena, Arianna & Chiara) e addolcita dal ghiotto rinfresco preparato per noi durante la notte dal Mago Silente.
Alla simultanea hanno partecipato in 17 (diciassette), grazie anche alla collaborazione del professor Nazario Renzoni, che ha accompagnato e sostenuto un’agguerrita rappresentanza del Liceo Scientifico Piero Gobetti. Una cura e un affetto che i suoi ragazzi gli hanno ricambiato nell’affollato momento del rinfresco, allorché si sono premurati che il prof. non restasse a bocca asciutta! Molto bravi anche i giovanissimi sestesi e i piccoli fiorentini, ma bravo soprattutto il Maestro Internazionale Vangjel Buli che interpreta i nuovi scacchi in modo da svelarne tutta la ricchezza e la profondità. Molte le patte d’incoraggiamento concesse.
Bravissime e professionali le undicenni ballerine che si esibivano nell’interregno tra simultanea e mangia-mangia e che sono riuscite ad incantare un pubblico non così abituato alla danza.
Infine il rinfresco. Che dire? Il Mago Silente dovrà abbondare un po’ negli anni avvenire, vista la velocità con cui grandi e piccini hanno spazzolato con soddisfazione pizzette e dolcini.
Dovremmo forse dedicare una riga a chi non c’era o a chi non è venuto, ma siccome sono venuti proprio tutti – anche chi atteso non era – più contenti siamo di non doversi dispiacere dell’assenza di nessuno!
