The Cuernavaca Young Masters was held in Mexico from February 1st to 11th, 2006, a round robin tournament with ten of the world's strongest under 24-year-old players. It was won by former FIDE world champion Ruslan Ponomariov and Spain's strongest GM Francisco Vallejo Pons. Both finished on 6.5/9, with Ponomariov having the slightly better tiebreak score (25.75:24.75). Here are the final standings:

Notes and annotations by Seppe De Vreesse-Pieters

A tournament always changes his face after a rest day, and that was exactly what happened on Tuesday the 7th of February. On day five all the games were decided! The biggest surprise was the loss of Nakamura, the leader of the tournament, against Leinier Domínguez. Nakamura once again played "lightning" chess, in a somewhat controversial style. White always seemed to be better in an unusual French defense. Nakamura missed some accurate defensive moves, due to his impatient fast play.

In round five Vallejo Pons outplayed Felgaer, and Bruzón’s openings experiment was severely punished by Ivan Cheparinov who, together with Volokitin and Domínguez, could realize his first win. León Hoyos and Ponomariov played a game where White made a positional blunder on move 16.b4?!, unnecessarily weakening his queen flank, defended well, reached equality and blundered then on move with 34.a4.

In round five we also witnessed the resurrection of Volokitin against Karjakin, cracking up a Berlin Defense in an interesting way with the rare 11.Be3, following Motylev-Karjakin, Sanjin, 2005. This is an important game for Berlin Defense lovers.

Round six

In round six Vallejo Pons really steamed through, showing excellent preparation against Karjakin, who suffered a second loss in sequence. Fatigue after the long Wijk aan Zee battles maybe a factor, but Vallejo simply is playing excellent chess. In this game he uncorked an improvement in comparison to Karjakin-Sokolov, Corus, 2006.

Well done by Vallejo Pons, who is in perfect shape to play the Linares tournament in Morelia, Mexico from February 18 till February 26 together with Topalov, Leko, Svidler, Aronian, Ivanchuk, Bacrot and Radjabov.

Cheparinov and Domínguez played a clean game that ended up in a draw. Volokitin had an incredible advantage against León Hoyos, outplaying the Mexican in a accelerated dragon, and then letting the advantage slip away, to win in an endgame after a passive and bad defense by Black. A second win in a row for Volokitin.

Nakamura prepared for an accelerated dragon against Felgaer, but at the last moment he pulled another big surprise out of his hat: 1.e5 c5 2.Nf3 Nc6 3.Nc3 g6 4.a3?!Bg7 5.Rb1 It lead to an obviously inferior position for white, but Felgaer handled the position really badly in the heat of the moment. Poor Rubén is having a horrible tournament, being the only one without a single win.

Players (Volokitin, Nakamura, Karjakin) and a mother (Tanya Karjakina) in Mexico

Again 4 wins and 1 draw that was fought all the way. The Sofia rules and the game rhythm of 100 minutes for 40 moves with a 30 seconds increment really works out: Sometimes it lowers the quality of the games but it raises the level of the spectacle like many of the “internauts” on playchess can confirm.

Round seven

Another day of surprises, although there were only two wins. The first one of Lázaro Bruzón against Volokitin and another one for Cheparinov in a French defense against the unlucky Felgaer. Bruzón proved that his pair of bishops was better than Volokitin’s pair of knights in a closed position of the King's Indian Defence. He beautifully outplayed Andrei in the endgame.

Joint leaders Vallejo Pons and Ruslan Ponomariov battled for the win respectively against Nakamura and Domínguez but only Vallejo Pons seemed to have real chances against Hikaru who played again an extravagant opening which leaded to a pawn loss and an inferior position, which he could resolve by his tactical brilliancy.

The show of the day was the game León Hoyos-Karjakin which begun as a boring game, that turned into a spectacle after some nice counterpunching by local Manuel León.

Day 8

Since day six there have been few changes in the positions of the players. Still Ponomariov and Vallejo Pons are in the lead, they are the ones (together with Cuban Leinier Domínguez) who didn’t suffer a single loss. Both were on +3 and come on +4 having a shared ticket to win the tournament since they both play each other on day 9.

Karjakin showed again his bad shape in his game against Nakamura, getting nowhere in another rare French Defense, only managing to save a draw after some missed chances by Hikaru. Domínguez played another Petrov-Defense against ‘Volo’ that resulted to be yet again a way to equalize, but nothing more.

Lázaro Bruzón, his Cuban compatriot won his second game of the tournament against León Hoyos who played again unambitiously:

Black moves and wins – solution on the end of this report.

The two games ended strangely. It seems that the light went out at 8 o’clock in Cuernavaca, due to an energy failure, something that is quite usual in México. Both games had to played on in the Hotel 1 hour later. In the case of Cheparinov it was exactly in the position where he avoided the draw, and in case of Felgaer it was in the position were he had played Qxf4, missing out a better defence with Bxe7 instead of Bxd4. Maybe both players were affected. Joint leaders Ponomariov and Vallejo Pons surely were happy with there results.

Paco Vallejo Pons played a complicated game against Cheparinov which resulted in the following position.

White has a simple draw playing Ra8-a7, since Blacks king can’t go on the b-file because of Rxb5+ and QxQd6.

Ponomariov played a very complicated game against Felgaer, who seemed to be just bad in the opening. The game continuation showed on the other hand that it wasn’t so clear at all.
