Fischerandom Chaos

La prima macchina per calcolare fu inventata e costruita nel 1643 dal filosofo e matematico Pascal. Verso la fine dello stesso secolo, il filosofo e matematico Leibniz discusse una possibilità più ambiziosa: arrivare grazie a un linguaggio “universalizzato”, addirittura alla macchina per pensare. Con i computer o cervelli elettronici d’oggi, ci siamo più o meno arrivati; l’“automazione del pensiero” è sulla buona strada...
O sulla cattiva? Converrà continuare così, o non sarà meglio tornare alla buona, semplice, vecchia tavola pitagorica?

Posizione 829
[FEN "rknbqrbn/pppppppp/8/8/8/8/PPPPPPPP/RKNBQRBN"]

[Mamedjarov - Kamsky, Magonza 2007]La posizione presenta una debolezza congenita per entrambi: i Pedoni g2 e g7 indifesi! Negli scacchi classici – la mitica posizione 518 – i Pedoni sono invece tutti difesi! 1. d4 Il precedente (!!!) era 1. e4 c5? (1. ... e5!) 2. f3! Ab6?? (2. ... d6 3. Dg3 Cg6 4. Axc5 ove se 4. ... Db5 allora 5. Cd3 ±) 3. Dg3+ e requiem, Bacrot – Lanka, Magonza 2005. 1. ... f5 2. f3 Cd6 3. c3 Cg6 4. f4? Un “tempo” perduto per scongiurare e7-e5. 4. ... Ad5 5. Df2 e6 6. Ab3 Ae4+ 7. Cd3 Vieppiù compromettente. 7. ... Ch4! 8. g3?? Per non cedere un Pedone (8. Cg3 Axg2)... 8. ... Cg6... il Bianco piange e seppellisce un Cavallo! 0 : 1.

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!
