Jonathan Zavala v Timur Gareev

Tom Brownscombe and Timur Gareev

Tom Brownscombe and Jaan Ehlvest

On Friday, December 6th, 2013 not just one, but two grandmasters came to visit the Las Vegas Chess Center at the corner of Fremont Street and 8th Street in downtown Las Vegas. GM Timur Gareev is number 3 on the most recent list of top USA players with a USCF rating of 2769 and 102 in the world with a current FIDE rating of 2650. GM Jaan Ehlvest is number 16 on the most recent list of USA players with a USCF rating of 2627 and 297 in the world with a current FIDE rating of 2577. And both of these players demonstrated their abilities at the Las Vegas Chess Center on Friday night.
The evening began with a presentation by Timur on how to play the white pieces against the dragon variation of the Sicilian defense. Then the two grandmasters teamed up against 20 club members in a tandem simultaneous chess exhibition. Many chess aficionados have seen a simultaneous chess exhibition, in which a strong player plays against many opponents simultaneously. But a tandem simultaneous exhibition is even more impressive. The two grandmasters moved from board to board, taking turns making moves without ever speaking to each other. This is much more difficult than a normal simultaneous exhibition, because the two grandmasters had to manage to play a coherent game of chess on every board without ever communicating with each other in any way (other than making the best moves they could on the chess boards). The grandmasters’ task was made even more difficult by the strength of the field, which included three masters. So it was hardly a surprise that one of the masters managed to achieve a victory.

The big surprise of the night occurred in Rhomer Johnson’s game. Rhomer holds a current USCF rating of just 1113. He has not even played against a master level opponent in USCF rated tournament competition in over 20 years. And in the opening and early middlegame, he appeared to be completely outclassed by his grandmaster opponents. Rhomer traded off his good bishop. Then he lost a center pawn. Then his opponents gained space and generated play on the queenside and in the center. But Rhomer didn’t give up. Despite having an objectively lost position, he kept on fighting. Rhomer played for a kingside attack and generated threats against black’s castled king. And those threats led to a blunder by one of the grandmasters, followed by resignation.

Congratulations Rhomer Johnson, bane of the grandmasters.

Thirty-eight chess players came to the Venetian®|The Palazzo® Congress Center on Saturday, December 7th and Sunday, December 8th to compete in the Second Las Vegas Mind Sports Open Chess Tournament. This tournament was part of the second Las Vegas Mind Sports Festival. The Festival included competitions in chess, scrabble, go, the trading card game Magic the Gathering, and other strategy games. Grandmasters Timur Gareev and Jaan Ehlvest were the pre-tournament favorites in the open section of the chess tournament, and they demonstrated their skills by drawing against each other and defeating all others to tie for first place in the open section with 4.5 out of a possible 5 points. Timur won the first place medal on tie-breaks, but the two grandmasters shared the first and second place prize money equally. FM Nachum Salman, NM Ronald Gross, Glenn Bidari, Virgilio Reyes, Juan Jauregui, Daniel Dease, William Wijaya, and Jonathan Zavala all tied for third through tenth place in the open section with 3 points each. They split the remaining prize money equally. But young Jonathan Zavala earned the third place medal due to his excellent tie-break score, even though he was the lowest rated player in this massive tie. Here are two of the key games, with notes by GM Gareev:
