David Friedgood: introducing myself

1/7/2012 – Chess problems are a world of their own. They share with chess the rules of the game, but introduce dimensions that are missing in the over-the-board version. We are glad to welcome a new contributor to our somewhat sporadic section on problem chess, which was nevertheless very popular with our readers. We wish you happy solving over the weekend.

The Lewis Chessmen: Lillören's misdemeanor

1/6/2012 – The Icelanders are not going to give in: in the battle with the Norwegians over the origin of the famous Lewis Chessmen – a collection of chess pieces, handcrafted in the 12th century – they repudiate the recent article by Morten Lillören disputing the Icelandic origin. This was the subject of a symposium on the Chessmen held in the location of their assumed origin.

54th Reggio Emilia: Giri beats Nakamura to tie for lead

1/5/2012 – The ninth and penultimate round was as dramatic as could be, and for all the right reasons as far as fans were concerned.

In the women's event the final round will also decide. Report, games, and interview with Giri.

A Gross Miscarriage of Justice in Computer Chess (part four)

1/5/2012 – As proof that Vas Rajlich had copied program code the ICGA presented pages and pages of Fruit and Rybka code side by side. But, according to Dr Søren Riis, what was labeled as Rybka code was actually fabricated to look like Fruit. He criticizes the ICGA's process failures and ruminates on the reasons behind the unprecedented vendetta launched against the star chess programmer.

Bologan: The Catalan – A Complete Repertoire for White

1/4/2012 – It is one of the most solid openings for White and forms part of the large and strong fianchetto family in which White builds his strategy mainly around the bishop on g2. This DVD by GM Viktor Bologan covers all of Black’s replies to the Catalan, some of which can even transpose to other openings such as the Tarrasch System and the Queen’s Indian. Chess Cafe review by Carsten Hansen.

54th Reggio Emilia: Ivanchuk has a meltdown

1/4/2012 – Normally, the news would be that Morozevich beat Nakamura (which he did) and is now right behind (which he is), followed by Giri in third, but Ivanchuk stole their thunder. In round seven, visibly haunted by his loss to Giri, he dropped a piece against Vitiugov in such a way that spectators were left gaping. In round eight, against Caruana, he just flipped and literally tried to give away all his pieces!

A Gross Miscarriage of Justice in Computer Chess (part three)

1/4/2012 – A core accusation against Vas Rajlich is that Rybka and Fruit have very similar positional evaluations, and the use of floating point numbers in Rybka’s time management code had to be copied from Fruit. Søren Riis enumerates the ten substantive evaluation differences and shows how the second accusation boils down to a single misplaced keystroke with zero impact on Rybka's play.

Master Moves #20

1/3/2012 – All the deepest plans or endgame technique are useless if you fall victim to a shot that leaves you in a lost position. Likewise, sometimes that superior play will only offer a single window of opportunity to deliver that final blow, so it is vital to be ready for it when it does. All the shots that follow were played at the Groningen Chess Festival. Go on and strut your stuff!

A Gross Miscarriage of Justice in Computer Chess (part two)

1/3/2012 – In this part Dr Søren Riis of Queen Mary University in London shows how most programs (legally) profited from Fruit, and subsequently much more so from the (illegally) reverse engineered Rybka. Yet it is Vasik Rajlich who was investigated, found guilty of plagiarism, banned for life, stripped of his titles, and vilified in the international press – for a five-year-old alleged tournament rule violation. Ironic.

Donostia/San Sebastián: and then there were eight

1/2/2012 – We remind you: this is an extraordinary knock-out event in that the participants have to play two games against each other – simultaneously.

A Gross Miscarriage of Justice in Computer Chess (part one)

1/2/2012 – "Biggest Sporting Scandal since Ben Johnson" and "Czech Mate, Mr. Cheat" – these were headlines in newspapers around the world six months ago.

54th Reggio Emilia: Spaceship Nakamura takes off

1/1/2012 – It was an impressive turnaround when, in round four, Nakamura downed Giri in a game where the young Dutchman seemed out of sorts, while Morozevich lost his lead when he was defeated by Ivanchuk in an exciting game. This was only a prelude to round five when Nakamura and Ivanchuk had a thrilling battle, which gave the American the sole lead. Pictures and New Year wishes.
