On July 31 in a small Baden-Wuerttemberg village in the Stuttgart region of Germany, a new record was set for playing Tandem Blindfold Chess.  
They are an unlikely looking pair: Timur Gareyev, an unconventional American grandmaster from Uzbekistan with unique hair, curious style of dress and a thirst for adventure; and Marc Lang, a Fide Master, who is a hard-working family man and currently holds the world record for playing 46 Blindfold Chess games simultaneously.  
Gareyev is currently training to beat Lang's world record by playing 50 blindfold chess games next year.
Gareyev is the former Executive Director of the Karpov Chess School in Lindsborg. The Karpov Chess School provides chess instruction to several school programs in McPherson, including Eisenhower Elementary, Washington Elementary, as well as home schoolers that were visited by Grandmaster Gareyev in the recent past. In May 2014, Gareyev played several games against local chess players at the McPherson Museum.
The school's president, Marck Cobb, attended the tournament as an observer.
“What was truly amazing is the complexity involved for two blindfold chess players, playing as a team, without knowing how the other blindfold player will make his move,” Cobb said.
A tandem blindfold chess exhibition involves two players who team up to play multiple chess games with a number of other opponents, making successive moves without consulting one another. Neither partner has sight of the board or the pieces.  
Alexander Alekhine and George Koltanowski set the world record for Tandem Blindfold Chess in 1934 in Antwerp, Belgium. As a team, they played six opponents, scoring three wins, one loss and two draws. Lang and Gareyev broke this 80-year record by playing seven opponents. Together they won five games and drew two.
Though unable to see the board, Gareyev and Lang tracked piece movements in their heads while all players announced their moves verbally. Each round of moves on the seven games took about eight minutes.
“What is interesting is that one of the blindfold players would have to change his strategy in response to his tandem player's previous move,” Cobb said. “Thus, you have two players trying to play the game as one and both of them cannot see the board or know what the next move will be by his 'partner' in this tandem event.”
The two played as white on six boards and black on one. The ages of their opponents ranged from 14 to 50 years. The entire match lasted four and a half hours, concluding about 15 minutes after midnight, with short breaks.
“From my perspective, it wasn't that difficult and I think Timur felt the same,” Lang said. “For me it was sometimes difficult to guess what Timur had in mind with his move, as he's the much stronger player. However, some of the positions didn't quite fit my style, which told in my play on that particular board.”
Though the match was long, Cobb said he was glad to have seen the two players work together.
“The opportunity to watch someone from the US to team with someone he had not previously met from Germany and play a tandem blindfold simultaneous game with extremely positive results was a display of the power of the mind, as well as the value of chess as an international means of peaceful communication,” he said. “The ability of chess to develop the strong mental capacities in these players continues to show the value of chess to enhance the thinking process and to improve the decision-making process that is used in day-to-day life.”
