Congratulations to 26 y/o Sam Shankland 2701.4 (+30.4 and up 25 positions), who wins the US Championship with 8.5/11 and enters the 2700 club for the first time!

It was a fantastic final sprint as both Fabiano Caruana and Sam Shankland fought to win their games to deny each other the title. Sam Shankland won again, giving his rival Fabiano Caruana no chance to steal it, and thus became the 2018 US Champion with a near 2900 performance. Nazi Paikidze and Annie Wang finished tied and will decide the title in a playoff on Monday. Report and analysis by GM Alex Yermolinsky | Photo: Lennart Ootes


Nazi and Sam win US Chess Championships

Samuel Shankland az új amerikai sakkbajnok, fél ponttal előzte meg Fabiano Caruanát

A 26 esztendős Samuel Shankland az új amerikai bajnok. A viadal utolsó fordulójában legyőzte a mezőny legfiatalabb résztvevőjét Awonder Liangot, megőrizte félpontos előnyét Fabiano Caruanával szemben. Shankland veretlenül végzett az élen, 30 Élő-pontot is gyűjtött, remek a performance pontszáma, 50 ezer dolláros első díjat vehetett át.
A bakui aranyérmes válogatott negyedik táblása, a rajtlistán ötödik 26 éves Samuel Shankland eddigi pályafutása legjobb versenyét játszva diadalmaskodott. Veretlenül játszotta végig a viadalt, hat győzelméből négyet sötéttel ért el.

Az amerikai sakkozás fellegvárának számító Saint Louis-ban ismét kitűnően szervezték meg a bajnokságot. A kommentátorok, Jennifer Shahade, Yasser Seirawan és Maurice Ashley remek munkát végeztek, élvezetessé tették a játszmák követését. 

Csak irigykedhetünk, hogy évről-évre a legjobbak játszanak, míg nálunk 2013 óta nem rendeztek meghívásos bajnokságot.

While the men have sorted it all out, two of the ladies out there have some unfinished business to settle over a small matter of the National Championship. The 2016 Champ, Nazi Paikidze, and the revelation of the 2018 event, Annie Wang, will be facing each other in a playoff match on Monday.

Annie was ahead by half a point going into today's game, but, in all honesty, her play in the final stretch was a little sub-par. Two wins over Sharevich and Krush could have easily been two losses, while the draws held against Paikidze and Zatonskih were good, but not decisive for the outcome of the tournament. The moment of truth arrived as Annie faced the defending Champion, Sabina Foisor.

Sabina Foisor 1-0 Annie Wang

Kudos to Sabina, who fought like a true champion in a situation where it hardly mattered for her tournament standing | Photo: Lennart Ootes

Paikidze had White against her former and current countrywoman, Rusudan Goletiani. Both hailing from Georgia, both are attractive and articulate young ladies, and both are great additions to American chess. A tense fight was on. A typical Scheveningen Sicilian setup promised chances for both sides, but at the end, just before the time control, the position appeared to be about even. A draw was agreed, setting up tomorrow's showdown.

The games are approaching the first time control, and it looks as if we might have a new Women's Chess Champion! Nazi Paiki 's position is busted, a loss would give Annie Wang the title with one round to spare!

Wang continues playing bullet chess, while Zatonskih is following the main line. Unfortunately for Anna, she is spending an immense amount of time to find the most natural moves, time trouble will surely be a factor in the ensuing middle game

Visit the worldchesshof's newest exhibition, The Sinquefield Effect: The Resurgence of American Chess, as we celebrate 10 years of US Chess Champs in Saint Louis.

Krush converts he endgame advantage and takes home the full point against Tatev__A US Chess Champs

What a roller coaster round!

Lenderman is playing incredible chess and is now heading towards his 3rd consecutive victory! The bishop pair and the central passed pawn will be huge assets for White US Chess Champs
