Is there really a mate in 9 ?

Ed Trice claims at his page: http://www.gothicchess.com/gv_release.html , that there would be a mate in 9 moves to be found by his Vortex in the shown position. But is this really true?

P.S.: of course, that old SMIRF version has no more chance there to avoid a defeat. Vortex detects the correct key move. But it would be nice to see how the 9 move mate should look like.

A Perfect Chancellor's Vortex



If you go to this link you can replay a recent great game between Twirling_Fern and GothicInventor.

It was also Game 2580 on the live site, but errors with the interface caused quite a few problems for Black. Unable to move his queen as early as move 12, GothicInventor had to resort to mobilizing as many pieces as possible towards the opposing king in order to create attacking chances.

The result: a game winning Chancellor's Vortex that is well worth replaying. Enjoy!

Vortex vs. Joker80, a Wild Game!



Last night Gothic Vortex played an hour-long game against H.G. Muller's Joker80 program. I must say, this was the most unusual game of Gothic Chess I have ever seen! Shown above is the position after 16. Ae3!? to this game:

Vortex vs. Joker80

I will annotate this game later, but feel free to comment on it here.

Mate in 270



People have recently asked the question: "How much stronger is Gothic Vortex Nucelar V than Gothic Vortex Gold IV?"

The diagram above should help answer that question.

Vortex V has the 5-piece Gothic Chess tablebases. These tablebases are probed in RAM as the program searches, they are not just used when you enter into a 5-piece position.

Therefore, Vortex can see that the trades from this position shown above will force black into a pawn-down ending of Queen and Pawn vs. Queen where the side to move (white) will have a mate in 268 moves. The key to the win is 2. Cxh7! and it is the only move to win.

Vortex can announce this win after only 1 second of search (even though the screen shot shows 6 seconds... I didn't capture the first mate announcement quickly enough).

You can imagine there are countless cases as the endgame approaches that the over 300 billion positions can provide a deep insight that will affect the play at the root of the game tree. This makes Vortex play endgames the way God would play them: perfectly, delivering checkmate as quickly as possible, and never making a mistake!

The Death of Bobby Fischer - A New Mystery!

Bobby Fischer's final bizarre act

From U.K. source, the Telegraph

The American chess prodigy's eccentricities didn't end with his death. As Neil Tweedie discovered in Reykjavik this week, the reclusive genius had arranged his own secret 'guerrilla' burial. Now its legality is being questioned

The grave was dug in secret as darkness descended over the white frozen landscape around the village of Hraungerdi, ready for Bobby Fischer's last getaway. Not even the minister whose churchyard it was knew of the funeral planned for the following morning.


Marriage mate: Miyoko Watai
Only five people attended the brief service early on Monday, conducted in the half-light before the short Icelandic day had properly begun. Among them was Gardar Sverrisson, Fischer's closest friend of the last few years and the man who had organised the digging of the grave without seeking the permission of Iceland's Lutheran Church or of the state authorities.

Sverrisson had also secured the services of a Roman Catholic priest from Reykjavik, some 30 miles to the west. Fischer was not a Catholic but must have been content with the arrangement - Sverrisson would have followed the American's instructions to the letter. The fifth mourner may or may not have been Fischer's wife, a Japanese woman named Miyoko Watai.

So much about Bobby Fischer was a mystery. He liked it that way, keeping people guessing. No way would the fallen angel of world chess have allowed the media a feeding frenzy. Hence the unauthorised "guerrilla" funeral uncovered by the Telegraph this week; a strange secret end to a strange secret life.

Bobby Fischer was 64 when he died last week of kidney failure - one year on earth for each square on a chessboard. Arguably the greatest chess player ever, he ended his life as a recluse, obsessed about his privacy, trusting in virtually no one. Subject to bouts of paranoia, he was vehemently anti-Semitic and convinced the CIA was out to get him. But he was also capable of kindness, gentleness and humour, and commanded loyalty among those who knew him.

He was an exile, too, a fugitive sought by the US government (he had broken sanctions against playing chess in Milosevic's Yugoslavia) but protected by the tiny country that had offered him a passport and a haven. His death made headlines around the world. There was much that Fischer kept to himself: his marriage, if marriage it was, and his daughter, a little girl living far away in the Philippines who may inherit all or part of his still considerable fortune.

The manner of his burial is now the subject of controversy in Iceland, an intimate society of just 300,000 people. Some of Fischer's friends believe the burial is unlawful. If Miss Watai was not his wife, they argue, then she and Sverrisson had no right to carry out the burial without seeking the permission of his estate's legal representatives. There is the additional matter of money: Fischer's Swiss bank account is thought to have held about £1.5 million, and there may be more in gold deposits.

Kristinn Fridfinnson is the Lutheran minister in Hraungerdi. He first knew that Fischer had become a permanent resident of his graveyard through the local media.

"I didn't believe it at first," he says, standing in the still cold air of the small church. "No one had asked my permission. It was a great surprise. Maybe it was a mistake to bring him here, so far from where he lived, but we are honoured to have him here now. The great Bobby Fischer."

Most of Fischer's public life is well documented, but his final years in Iceland are less well-known. Icelanders pride themselves on not being seduced by celebrity, preferring to leave famous visitors in peace. Fischer arrived in March 2005 and found a haven in Reykjavik, where he was supported by a small circle of friends. Some have broken their silence for the first time to talk of Fischer.

"Bobby could be such fun," said Einar Einarsson, one of those who helped get him into Iceland. "I remember him singing My Way as I drove him in the car. He could be gentle and kind, particularly to children. In many ways he was a quite normal person. But there was always that dark side - he believed that dark forces were out to get him."

Was he mad?

''I think that he was an angry man rather than a mad man."

Mr Einarsson was upset by his exclusion from Fischer's funeral and is concerned about its legality.

Saemi Palsson was another close friend. Fischer's police bodyguard during the Spassky match in 1972, he remained in contact with the chess player and was central to securing his release from custody in Japan, after he was arrested by immigration officials. He retains a great affection for the maverick American but admits to being disturbed by some of his more unpalatable views.

"Bobby was a genius, he could have been a great doctor, scientist - anything. But he was not emotionally intelligent - he didn't know how to behave with people. He did not trust many people. He did not trust doctors and that is why he did not want treatment for his condition."

Fischer's life in Reykjavik was a simple one. He was to be seen in the coffee shops and book stores of the Icelandic capital's bohemian quarter, reading and avoiding eye contact. In particular, he frequented the Bokin bookshop, which he would visit twice a week, occupying for hours a chair set aside especially for him in the corner. He devoured everything from history to biography, and was also fond of reading Dennis the Menace comic books imported for him from the US. People asking for autographs were greeted with stern silence.

Fischer's need for privacy was all consuming. Often he would arrive late at a restaurant so as to avoid unwelcome attention. But he was also to be spotted dining with friends, enjoying jokes.

His mercurial streak never left him, though. Friends fell in and out of favour depending on whim. Speaking to the media was a capital offence requiring immediate exclusion from his circle. And there was always potential for the explosive, irrational rant.

Miss Watai was based in Japan but visited Iceland frequently, especially as Fischer's health began to fail, doing his laundry and tending to him at his apartment in the capital. Some in the Fischer circle refer to Miss Watai merely as a "friend" of Fischer. The Japanese embassy in Reykjavik encouraged speculation about the couple's marital status this week when a spokesman questioned the validity of their civil wedding ceremony in Japan, alleging it may have been unlawful because of Fischer's lack of a valid passport at that time.

But another friend of Fischer came to Miss Watai's defence. She told the Telegraph: "There is simply no question that Miyoko was the closest person to Bobby and by far the most special person in his life. She is a woman of absolute integrity who will undoubtedly ensure his daughter is taken care of, should she inherit his estate. She met Bobby in the 1970s and there was probably a relationship from that time. She was passionate about him and is devastated by his death. She promised never to betray his confidences and she will observe that promise."

Robert James Fischer was a phenomenon. There has probably never been a more talented chess player. US junior champion at 13 and a grandmaster at 15, his winning streak of 21 games at top level will probably never be equalled. When so many players aimed for the draw, he went for the throat. He didn't beat opponents, he annihilated them.

Good-looking in his youth, and with a taste for sharp suits, he was saleable in a way that other chess players could only dream of, commanding multimillion-dollar offers in exchange for appearances. But he was mercurial and prone to anger.

It was in Iceland in 1972 that he attained worldwide notoriety, playing in the world championship against Boris Spassky. The match was a metaphor for the Cold War: American kid versus the might of the Soviet chess machine.

It would be 20 years before he played again. In the meantime, he descended into a kind of madness, donating money to a pseudo-religion promising Christ's return in 1975 and developing a loathing for Jews. That his mother Regina was Jewish mattered not. Fischer may even have had a Jewish father, a Hungarian scientist who had an affair with his mother. His legally recognised father, a German-born scientist, left home when his only son was two.

In 1992, a multimillion-dollar pot lured him back into the limelight, again against Spassky in a tournament in Milosevic's Yugoslavia, then the subject of US sanctions. From then on he was an exile, circling the globe. While in the Philippines he met a young woman called Justine. In 2000 she gave birth to a daughter, who could now inherit his estate.

Fischer took to the radio to denounce the US and Israel. The rant celebrating 9/11 was the last straw. In 2003 the US retaliated by revoking his passport. In 2004 Fischer was arrested at Tokyo airport and detained for eight months. It was then that he is said to have married Miyoko, president of the Japanese chess federation. Shortly after, Iceland granted him citizenship and he was released.

Lilja Gretarsdottir, president of the Icelandic chess federation, explains: "Icelanders have always had a soft spot for outlaws. It goes back to the sagas.

"Fischer was exiled from America but he was always an American - in his manner, everything. I think he must have found it hard to know that he could not return to his country."

In the churchyard at Hraungerdi yesterday, the red and white roses on Bobby Fischer's grave appeared as fresh as the day they were laid down upon it, frozen by the cutting Arctic wind. Driving snow obscured the last resting place of the most celebrated exponent of the art of chess.

The press didn't get their feeding frenzy. To the end, Bobby Fischer did it His Way.

Bobby Fischer's Widow Will Inherit 140 Million Kronur

Translated from Icelandic:


Miyoko Watai, Bobby Fischer´s widow, will inherit the 140 million Icelandic Kronur that Fischer left behind when he died. It has been confirmed that Watai was Fischer’s wife, but not his girlfriend, as has been argued so many times. She will inherit all of the 140 million Icelandic kronur according to the resources of Vísir that he left behind, as well as the 67 square meter apartment in Espigerði.

As was said in the noon news of Stöðvar 2, the ex brother in-law of Fischer and father to his two nephews, Russel Targ, is here to look out for the interests of his sons. According to him on the website of Morgunblaðið, it is his intention to see if Fischer has a legal wife, or children. If that is the case then he has nothing to do here. But if it is not so then Targ will make demands on Fischer´s holding in the name of his sons, since they are the next to kin relatives.

The assets that Fischer leaves behind is part of the prize money that he got for the notorious chess that he played with Boris Spassky in Sveti Stefan and Belgrad in 1992 and was the reason that he was wanted by the United States government.

The money was held for a long time in a Swiss bank account according to resources of Vísir but the bank revoked his business with Fischer shortly after he moved to Iceland, and they put this money into account in his name in Landsbankinn.

The apartment in Espigerði, which Fischer bought in 2004, is on the ninth floor. It is the top floor of the apartment building, and his close friend Garðar Sverrisson lives on the seventh floor.

It has long been argued that Fischer was a father to a girl in the Philippines but Vísir has no information that he was in contact with her mother since the child was born. Therefore all of Fischer´s assets will go Fischer´s wife, Miyoko Watai. They were close friends for a long time and got married when the argument of the extradition of Fischer from Japan to the United States was at its high point.

Original story in Icelandic:

Miyoko Watai, ekkja Bobby Fischer, mun erfa þær 140 milljónir sem Fischer skildi eftir sig við andlát sitt. Staðfest hefur verið að Watai var eiginkona Fischers en ekki unnusta eins og oft hefur verið haldið fram og mun því erfa þær rúmu 140 milljónir króna sem Vísir hefur heimildir fyrir að hann láti eftir sig, auk 67 fermetra íbúðar í Espigerði.

Eins og kom fram í hádegisfréttum Stöðvar 2 er fyrrverandi mágur Fischer og faðir tveggja systrasona hans, Russel Targ, hér á landi til þess að gæta hagsmuna sona sinna. Haft er eftir honum á vef Morgunblaðsins að hann vilji ganga úr skugga um hvort Fischer hafi skilið eftir sig eiginkonu eða börn. Sé það raunin eigi hann ekkert erindi hér. Sé það hins vegar ekki raunin mun Targ væntanlega gera kröfu í eigur Fischer í nafni sona sinna enda þeir hans nánustu eftirlifandi ættingjar.

Fjármunirnir sem Fischer lætur eftir sig er hluti af verðlaunafé sem hann fékk fyrir hið umdeilda skákeingvígi sem hann háði við Boris Spassky í Sveti Stefan og Belgrad árið 1992 og olli því að hann lenti upp á kant við bandarísk stjórnvöld.

Því var lengi haldið föstu inn á svissneskum bankareikningum en samkvæmt heimildum Vísis rifti bankinn viðskiptum sínum við Fischer skömmu eftir að hann settist að hér á landi og lagði peningana inn á reikning í hans nafni í Landsbankanum.

Íbúðina í Espigerði keypti Fischer árið 2004. Hún er á níundu og efstu hæð í fjölbýli en náinn vinur hans, Garðar Sverrisson, býr á sjöundu hæðinni.

Því hefur lengi verið haldið fram að Fischer hafi feðrað stúlku á Filippseyjum en Vísir hefur ekki upplýsingar um að hann hafi verið í samskiptum við móður hennar síðan. Þar afleiðandi munu eigur Fischer renna óskipt til eiginkonu sinnar Miyoko Watai. Þau voru lengi nánir vinir og giftu sig þegar deilan um framsal hans frá Japan til Bandaríkjanna stóð sem hæst.

Bobby Fischer, 1943-2008



Bobby Fischer, March 9, 1943 – January 17, 2008, was buried today. The funeral was at the Laugardalur Catholic Church just outside of Selfoss, which is about 37 miles south of Reykjavik. According to Reverend Kristinn Agust Fridfinnsson, Fischer's Last Will And Testament mandated a private ceremony with only a few people in attendance. Gardar Sverrisson and Miyoko Watai were among those present.

According to the archives of the former GothicChessLive.com server, the last game played by Fischer was on Tuesday, April 25, 2006, at approximately 1:32 PM Eastern. It was a 10/0 game against me where he let 7 minutes come off of his clock at the start of the game before making move 1. The game went 55 moves ending in a repetition draw with Bobby still having about 30 seconds on his clock. The 'umbra' account on GothicChessLive never signed on again.

2007 Gothic Chess Computer World Championship - Final Standings



Here are the final standings for the 2007 Gothic Chess Computer World Championship:

1-2, Gothic Vortex, 13.0-1.0
1-2, Variant Pulverizer, 13.0-1.0
3, Tornado, 9.0-5.0
4, SMIRF, 8.0-6.0
5, TSCP Gothic 64, 6.0-8.0
6, fmax4, 4.5-9.5
7, ChessV, 2.0-10.0
8, Zillions 2, 0.5-13.5

It was a more exciting event this year featuring a "surprise element" with the new programs Variant Pulverizer and Tornado making strong showings. Tornado had the unfortunate experience of being paired against the strongest programs early on, so it fought from deep within a hole to emerge into a solid third place showing.

Pulverizer has the best time management code I have ever seen. Literally in ever strong position it had, it would move within a few seconds. When the opponent would seem to be regaining ground, it would make wise use of its time and send the other program back into much more difficult positions. Once it had a solid win, it would never use more than 5 minutes remaining to play out the rest of its game.

fmax was another welcomed edition to the event. Programmed by H.G. Muller, this program contains hardly 2000 characters of source code and was deliberately designed to the be the smallest Gothic Chess program ever! I would like to remind everyone that it's draw against Zillions 2 early on was the result of a very bad bug, and fmax could have finished with 5 points just 1 point behind TSCP Gothic which was the second place finisher in several Gothic Chess Championships! This year, the event featured its strongest competitors yet, so fmax had a tough time dealing with the more elaborate programs out there.

TSCP Gothic is still the fastest searching Gothic Chess program with observed speeds of over 1.1 million nodes per second at times on the 2.4 GHz AMD machine on which all programs ran. Its lower finish this year seems to indicate the pendulum has swung to favor slower, better evaluations rather than faster, brute force methods. Recall even in 2004, it seemed "faster dumber" programs in Gothic were outperforming the slower "more intelligent" ones, but this seems to have reveresed, for the time being.

The SMIRF program had submitted two changes during the event, with unknown overall effectiveness. Had these changes been made earlier, SMIRF may have done better, but time will tell. A 4th place finish in this event is still very respectable. We look forward to the future and wonder if SMIRF will support the Winboard_F protocol, which will no doubt be the future of this annual event.

The ChessV program continues to finish at the "bottom of the barrel" when you consider that Zillions 2 is not a dedicated engine but a scripted, compiled, general-purpose interpretter. While ChessV does allow for the play of many so-called variants, it must play them all poorly based on its nearly dead-last finish in 2007. It is safe to say that ChessV is in need of a complete redesign.
