Chess Software vs Human Brain

I want to know who is the World Chess Champion (WCC) 2010, but have to wait for result of the match that is scheduled to take place in Sofia, Bulgaria from April 23 to May 12, 2010. In the WCC 2010, the current world champion, Viswanathan Anand (India), will be challenged for the World Chess Championship title by Veselin Topalov (Bulgaria), with a prize fund of 2 million euros. 

According to FIDE Chess Profile on March 2010, Viswanathan Anand is 4th world rank, got FIDE title Grand Master in 1985, rating: 2787, B-Year 1969. He is current world champion, who won the World Chess Championship 2007 and successfully defended his title against Vladimir Kramnik in the World Chess Championship 2008.

Veselin Topalov got FIDE title Grand Master in 1992 and International Master (IM) in 1989, rating: 2805, B-Year 1975, and 2nd world rank.

I then search (goggling) their profile and road to be a World Champion and Challenger. I came to World Chess Championship 2006 and found "Bathroom controversy". The WCC 2006 was a chess match between Classical WCC Vladimir Kramnik, and FIDE WCC Veselin Topalov. The match, which was won by Kramnik, determined, for the first time in 13 years, the undisputed WCC. The match was played between September 23 and October 13, 2006, in Elista, Kalmykia, Russia

Here the piece parts that make me interested in writing this post:
--------
Allegations and forfeit
On September 28, 2006, the rest day between games 4 and 5, Topalov's manager Silvio Danailov complained to the match organizers and the press about Kramnik's repeated visits to the bathroom. He noted that the bathrooms are the only place not under audio or video surveillance, and called the frequency of the breaks "strange, if not suspicious". Danailov suggested that Topalov would abandon the match if the concerns were not addressed.

Reactions
On October 2 2006, more than 30 GMs, WGMs, and IMs expressed open support for Kramnik's position – including former World Champions Anatoly Karpov and Boris Spassky, whose opponent also famously disputed the match conditions.

On Later allegations section:
"On October 4, Topalov's manager, Silvio Danailov, issued a press release that identified what it labeled "coincidence statistics" showing the percentage of times that Kramnik played a move that would be recommended by Chessbase's Fritz 9 chessplaying software in that position (about 78% on average)."

GM Susan Polgar - who does not believe Kramnik is using computer assistance - characterized this as "another black eye for Danailov and chess. Even if he believes that it is true, he should complain to the committee and not through a press release. This is unprofessional and unacceptable."

At the press conference following Game 7, Kramnik commented on the second game where the Fritz analysis had shown a match with 87% of Kramnik's moves. Kramnik said "A proper analysis must take into consideration that in the second game we both blundered a mate in three! First of all, this 87% is total nonsense – everything depends on the time allotted to the engine for analyzing a given position. Secondly, Topalov’s percentages in San Luis, for example, were even higher."

In an interview with the Spanish daily ABC published on 14 December 2006, Topalov alleged that Kramnik had cheated with computer help during the match, that network cables had been found in the bathroom ceiling, that threats were issued, and that he felt physically unsafe during the match.

I don' t know what happened, but I remember while playing online chess in www.chess.com I have been seeing that the staffs have detect cheating and close cheaters account.  Sure, I am not use chess program of any kind of computer help here.

I have read IBM Deep Blue versus Garry Kasparow. In 1996 Garry won 4-2, and for rematch in 1997 Deep Blue won 3,5 - 2,5.

How great the human brain .... but sometimes we feel tired, fatigue, exhausted, and the like.

Here is list of chess software.

My favourite Online Games


In 2009, my brother and I visited our mother (3 hours for my flight and 4 hours for my brother) we also bought a chess board and playing chess to fill our days. We played since childhood. We enjoy chess (and other sports too) because our father loved to play chess and I think it comes from our father's hobby. .....When playing chess, we then thought that maybe there is a game of chess online is available on the internet.

After returning from our mother place, I was goggling and found the game of chess online. I called my brother and we continue to fight again over internet (using GPS I measure that our air distance is about 900km ). Still...I could not defeat him.

By the way, I learned many things, from articles, quizzes, voting chess, opening and variants, analysis, etc.. Also, I can join the tournament among nations or among special teams.

My best score is 1,794 (201 wins, 12 loses, and 34 drawn) and today I am ranked 10,373 of 93,999 players. Scores of new players is the beginning of 1,200. The highest score for today is 2,996. Soon I'll get the 1,800 score tepuktangan. Here a sample of my game that I won. My friend is a good player and have 2,044 score while I was 1,758, but he loss on this game.

As I write this blog, there are 1,134,182 Members with 4,303 Teams and currently play 167,073 Games; Online members are 3,959; and 2,590 play Live chess.

This chess online use Glicko system (a chess rating system) as a method for calculating the relative skill levels of players. The Glicko system is currently implemented on the free internet chess server (FICS), and variations of the Glicko system have been adapted for several commercial internet gaming organizations such as ChronX, Case's Ladder, and the Gothic Chess Association.

Here, there are many players who have FM, NM, IM, CM title. Wish I could play with some of them but I have to win more games before I could make a challenge! ..a hope..

For a quick reference:

Candidate Master (CM)
The most usual way for a player to qualify for the Candidate Master title is by achieving an Elo rating of 2200 or more.

FIDE Master (FM)
The most usual way for a player to qualify for the FIDE Master title is by achieving an Elo rating of 2300 or more.

International Master (IM)
The title International Master is awarded to strong chess players. IMs usually have an Elo rating between 2400 and 2500. Sometimes, though, there may be a very strong IM who has not yet become a Grandmaster but has a rating greater than 2500.

The IM title can also be awarded for a few specific performances. For example, under current rules, the runner up at the World Junior Championship will be awarded the IM title if he or she does not already have it.

After becoming an IM, most professional players set their next goal as becoming a Grandmaster. It is also possible to become a Grandmaster without ever having been an International Master. Larry Christiansen of the United States (1977), Boris Gelfand of Israel (1988), and former World Champion Vladimir Kramnik of Russia all became Grandmasters without ever having been an IM. However, the more usual path is first to become an IM, then move on to the GM level.

International Master titles are also awarded to correspondence chess players by the International Correspondence Chess Federation (ICCF), and composers and solvers of chess problems.

Grandmaster (GM)
The title Grandmaster is awarded to outstanding chess players by FIDE. Apart from World Champion, Grandmaster is the highest title a chess player can attain. Once achieved, the title is held for life. This title can be awarded to the players with an Elo rating greater than 2500. Vishwanathan Anand, Garry Kasparov, and Vladimir Kramnik are a few examples of GMs.

What about you? Do you have any suggestions for other online games?
