Life at the Border

In a report to The Week in Chess (TWIC) dated April 28, 1996, International Master Siniša Joksić reviewed — with very little enthusiasm indeed — the first-ever International Fischerandom Tournament, which took place in the spring of that year in Kanjiža, a town in Serbia (then Yugoslavia) at the border with Hungary. The three-day 12-player round-robin featured two Grandmasters, four International Masters, four FIDE Masters, and two National Masters, with a time control of 25 minutes for 20 moves, plus 5 minutes for the remainder of the game. The random starting positions were generated by a set of four dice, signalling that not only Bobby Fischer did not reply to the organisers’ invitation for a symbolic attendance, but he did not even put his computerised shuffler to their disposal. Joksić adds that too often time scrambles prevented the organisers from collecting the games — in truth, some of them will appear in Svetozar Gligorić’s book “Shall We Play Fischerandom Chess?” (Batsford, London, 2002) — which implies that such a time control inevitably also affected the level of play.
The final standing was:

  1. Péter Lékó GM (HUN) 9½/11;
  2. Stanimir Nikolić GM (YUG) 9;
  3. Goran Vojinović IM (YUG) 7;
  4. Ervin Mozes IM (ROM) 6½
  5. Gáspár Máthé IM (HUN) 6½
  6. Vladimir Milošević FM (YUG) 6;
  7. Tibor Farkas FM (HUN) 5½
  8. Stevan Popov FM (YUG) 4½
  9. Mirko Mamuzić NM (YUG) 4;
10. Lajos Ábel IM (HUN) 3½
11. Vojislav Petrović FM (YUG) 2;
12. Sandor Lorinć NM (YUG) 2.

Finally, as a conclusion of the news release, the very short game between the only two Grandmasters competing was given almost without comment:

Position #67

1. d4 d5 2. g3 g6 3. Qh3 h5. Here one may only note that 3. ... e6 is also perfectly playable, owing to the fact that the h-Pawn is not en prise (for after 4. Qxh7? Bxd4! 5. Rxd4?? Rh8 the White Queen is trapped).
4. Bxd5 e6 5. Bg2 Rxd4 6. 0-0 Rxd1 7. Rxd1 Qe7 8. Nd3 Nd7 9. Nd2 Nd6 10. c4 Nf5 11. b3 Bxa1 12. Rxa1 0-0 13. g4 hxg4 14. Qxg4 b6


15. Nf3? Safer seems 15. Bxa8 Rxa8 16. Nf3 e5 17. e4 with balanced play.
15. ... Bxf3! 16. Bxf3 Kg7 17. Rd1 Rh8 ½ : ½. In his only comment on the game, Joksić stated that the draw was offered by Lékó, which may sound strange, especially as it seems likely that Black stands better.

Tea at Three

As the dean of chess journalists, Leonard Barden, has noted in his column on The Guardian, still “there is little guidance on the principles of good play [in Fischerandom chess]. Nakamura observed that you should avoid developing your Knights at e3/d3 because Black can easily keep them out of the game by e7-e6 or d7-d6. At least that’s a start. Instead of ‘Knight on the rim is dim’ we now have ‘Knight at d3, disagree’”.

A Castle in the Sky

5b1r/pp4pp/1n2k3/3pq3/3p4/3B4/PP1B2PP/3Q2KR b K - 0 1

The above diagram, showing a position with Black to move, was presented by Grandmaster Ruslan Olegovich Ponomariov as an instructive example of how counterintuitive the rules of castling in Fischerandom chess (a.k.a. chess960) at times appear to be. “At this position can Black prevent short castle by playing ... Qe5-f6?”, he asks. The answer is no — 1. ... Qf6 doesn’t prevent White’s h-side castling (2. 0-0), which, in the specific case, is performed by “Rook-move-only”, i.e. by the Rook jumping over the King. Not incidentally, the answer is also the solution of the puzzle/quiz, for after 1. ... Qf6 2. 0-0 Black might well resign.

It’s only a matter of going

https://www.splicetoday.com/writing/chess-and-its-alternatives
Besides the standard game, there are many chess variants: the starting positions of the pieces, or the use of non-standard pieces; the size and shape of the board or boards; the number of players; the rules for such operations as castling, Pawn promotion, draws, checks and checkmates; whether the game retains its symmetry between the contending sides, or its transparency, where all players can see the full board; whether some element of chance is introduced, as with a dice roll determining what pieces can move.
This makes for an interesting ferment, though no variant has yet approached the popularity of regular chess. A relatively popular one is Fischer Random Chess, also known as Chess960, invented by the troubled and brilliant late champion Bobby Fischer; relatively moderate in its differences from standard chess, this variant randomizes the initial placement of the pieces behind each row of Pawns, making for a more varied set of game openings.

 https://www.sportsradio.com.au/t20-chess-new-form-of-chess-threatens-to-send-tradition-packing/
Chess might be one of the oldest board games in existence, but its current form is being threatened by the rise in popularity of a more “challenging” set of rules.
It’s called “Chess 960” — an alternative format of the game designed by American champion Bobby Fischer, that is threatening to usurp traditional gameplay by making the game less predictable.
Concerns from officials at the World Chess Federation that technology has led to the human thought process being outsourced to computers has made them more willing to accept this new form of the game, where pieces are shuffled randomly before being placed on the board.
Pawns remain in the same position as they usually would to start, while all other pieces are moved around prior to the beginning of the match.
Chess 960, also known as “Fischer Random Chess” in honour of its creator, is named after the number of potential starting positions. [Read more].

Position #220

“Here is a sample of the sort of chess Fischerandom can lead to. It was played in 1995 in a small chess festival near Heidelberg and shows Karpov quickly getting into his normal positional stride, despite the curious opening position (see diagram)”, International Master William Roland Hartston wrote in his May 16, 1997 column for The Independent.

12. exd5? This appears a serious positional error, isolating the Pawn on d4. Any advice? In his book “Bobby Fischer Comes Home: The Final Years in Iceland, a Saga of Friendship and Lost Illusions”, New In Chess, Alkmaar, 2012, p. 83, Grandmaster Helgi Ólafsson — who was so lucky as to play a few games at Fischerandom chess with Bobby — wrote: “I noticed that in every game he tried to castle as soon as possible”. So why not to castle h-side (12. 0-0)?
12. ... Nxe3 13. Bxe3 Nxd5 14. Bd2 Be6 15. g3 Kf7 16. Ke2? Allowing Black to infiltrate on the h-file. A little better seems 16. Kf2 h5 17. h4, although after 17. ... Nb4 Black keeps a clear edge.

Bd3 Bd5 0 : 1. “Afterwards Karpov commented that as the game ‘did not produce the harmonious positions of normal chess’ it was ‘negative’ but he conceded that the player with the most talent would win”, David Brine Pritchard wrote in Variant Chess, Issue 18, Autumn 1995, p. 174.

25. Qa6? Gligorić regards this move as “suicidal”, but White’s position is desperate anyway, e.g. 25. 0-0 Ng4 26. h3 Nxe3 27. Nxe3 Nxd4 winning easily. 25. ... Bxe3 26. fxe3. Or 26. Nxe3 Rxf2 27. Qxc6 Qf4! 28. Qxe6+ Kh8 and finis. 26. ... Ng4 27. Qxc6 Qf6 0 : 1.

1. b3 Nf6. The g7-Pawn was attacked. 2. Bxf6. White voluntarily cedes the Bishop-pair, in the hope that his unbroken Pawn formation may tell in the ending.

Black’s preponderance of power on the a-side will soon become decisive.

Pavlovian

In an interview with Janis Nisii for Torre & Cavallo Scacco!, No. 7-8, July-August 2008, pp. 14-19, the “unnumbered” former World Chess Champion Veselin Aleksandrov Topalov, among other matters, gave his opinions about Fischerandom chess (a.k.a. chess960):

— What do you think of variants like chess960?
— For me, it is indifferent, but the problem with Fischerandom is for the mass of non-professional players. There are many players who don’t have too much time to study chess, but for example they have their Sicilian and with Fischerandom they could no longer play it. For me it’s fine, we professionals would adapt, but I doubt amateurs can do the same. Ordinary players want to go to the club on Saturday and play the French or the Sicilian. It would be a great tragedy for them because they do not want to lose their French!
