Chessplayers without frontal lobes
One may wonder why chessplayers are not reacting about this document:
Credit creation

My opinion: we have to establish a not-for-profit "Chessmen without frontal lobes" foundation, while all the world sink into economic craziness...

The Perreux Variation of the Two Knights Defense
http://studimonetari.org/edg/pdf/twoknightsperreux.pdf
Qui alcuni link utili, per studiare la variante con un po' di commenti:
The Perreux Variation of the Two Knights Defense
http://www.rci.rutgers.edu/~goeller/urusov/perreux/index.html
"The Perreux Variation of the Two Knights Defense typically arises after 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.d4 exd4 5.Ng5, or by transposition from the Urusov Gambit. Its name probably derives from the chess club of Perreux-sur-Marne (cercle du Perreux), just outside Paris, where it first became popular in the 19th century. Its sharp tactical themes are easy to grasp and make it attractive to beginning players, but it has also been played by masters who like that many lines lead to interesting endgame positions where good technique can win. As a forcing line, the Perreux Variation also has the advantage of limiting the number of subvariations, so the amount of opening theory is not large. Black is immediately forced to defend his f-pawn by either 5....Ne5 or 5....d5 "

Mosse premature di... Donna (Queen early moves)
Una delle tipiche regole dell'apertura degli scacchi - del tipo che il Cavallo non dovrebbe stare ai lati, nelle case al bordo della scacchiera - recita che la Donna, la Regina, non dovrebbe essere sviluppata troppo presto. Cioè andrebbe mossa dopo lo sviluppo di Cavalli ed Alfieri. TUTTAVIA, come in economia accade per la questione del signoraggio, i risultati della pratica contraddicono talvolta la teoria. Si prendano ad esempio le due seguenti posizioni - una per il Bianco ed una per il Nero - in cui proprio lo sviluppo anticipato della Donna dà un vantaggio "fuori dalla statistica" per il giocatore ardito:
B01 - Scandinavian defense
C22 - center game
Ora, non posso raccontarvi dettagli piccanti della nottata incredibile appena trascorsa, a seguito della presentazione dei disegni di Francis Bacon a Milano, perché anche la serendipità ha un suo limite.
Però vi posso certamente suggerire di fare particolare attenzione alle mosse premature delle... Donne.
Cliccando sotto potrete controllare rispettivamente la tavola pratica delle due varianti:
1.e4 d5 2.exd5 Nf6 3.Nf3 Qxd5 4.Nc3 Qd6
1.e4 e5 2.d4 exd4 3.Qxd4 Nc6 4.Qe3
Come potrete notare, nella prima variante il Nero ottiene un risultato del 54% di vittorie (rispetto ad una media generale del 46,1%). Nel secondo il Bianco, rispetto ad una media standard del 53,9%, ottiene un risultato del 55,5%...
Provare per credere, e soprattutto, non chiedetemi perché. Non lo voglio sapere nemmeno io.

A Complete Guide to Grivas Sicilian
In the book "A Complete Guide to Grivas Sicilian (2005)," the author Efstratios Grivas, after:
[ECO B33b] 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Nb3 Nf6 6.Nc3 e6 7.a3 Qc7
only examines the variations that arises after:
A) 8.Be3 (and Be2)
B) 8.Be3 (and Bd3)
C) 8.Bd3 (and Bd2)
But "Robbolito g3" suggest instead this line:
8.f4 d5 (N, 8...d6) 9.e5 Nd7 10.Nb5 Qd8 11.Be3 a6 12. N5d4 Be7
(with score: + 0.24)
which seems interesting and need further investigation.

Corus: Report of round 13 (poor prizes...)
Corus: Report of round 13
World champion Viswanathan Anand of India agreed to a draw after 39 moves with black from a Meraner against Loek van Wely to remain the only unbeaten competitor in the tournament’s highest division. But his track record of eleven draws and two victories got him no further than a shared fourth place. ‘Vishy’ tried, of course, but to no avail, and during the post-mortem he was heard to complain about his usually more aggressive opponent: “On the day that Loeky starts playing for a draw, what can a man do?”
The two runners-up at the outset of Sunday’s thirteenth round, Spain’s Alexei Shirov and Russia’s Vladimir Kramnik, remained just that: runners-up.
The situation remained unclear to the point where even Carlsen, who had come by to see what was happening on the neighbours’ board, was nonplussed. “I couldn’t figure out Shirov’s game,” he said. “But I was concentrating on my own game, of course.” You bet he did. A win for Shirov would mean the Norwegian needed a win himself to stay ahead in the race for an unshared first prize and whatever Carlsen may have thought of Shirov’s chances, he decided to go all out against Caruana regardless. Unfortunately, Carlsen said, “Caruana defended very well, while I miscalculated in the middle game.”
That meant a draw was enough for Carlsen to finish an unshared first but his ‘miscalculation’ had led to serious trouble, or rather, as he put it himself, “what I thought was a promising position, in fact turned out to be very bad. Fabiano and I both thought black should have excellent winning chances in the knight endgame.” He may have but neither experts nor computers were able to show how. “Surprisingly, I drew,” Carlsen explained, adding: “I had some good games; sometimes I played well and sometimes I played lousy. In the end, I won the tournament with a lot of luck.”
Shirov took half of the 10,500 euros for the combined second and third prize, and received a bonus when he and Dominguez were declared the co-winners of the 500-euro ‘Ymouth Versatile Prize’ for the day’s best performance in the tournament’s top group. Hikaru Nakamura of the U.S. scored the only victory on the last day of Corus A, downing Holland’s Sergei Tiviakov after a grueling 79 moves with white in a Scandinavian game. Vassili Ivanchuk and Peter Leko settled for a draw after 27 uneventful moves in a Meraner, but the way in which Nigel Short and Holland’s Jan Smeets reached the same result had chess fans on the edge of their seats. Both players used up oodles of time in a highly unusual but very entertaining Petroff before agreeing to split the point by repetition on their 14th.
China’s Li Chao finished the winner in Group C. Having secured first place the day before, he ended the tournament with a win over Dutch women’s champion Zhaoqing Peng in 41 moves from a French Opening.
