US Ch: Jennifer Yu takes the title with a round to spare

A breakthrough performance

In her first appearance at a US Women's Championship in 2015, Jennifer Yu finished last with a 2½/11 score, but she has only improved since then — she got five points in '16, six in '17 and six-and-a-half in last year's edition. Potentially, she could wrap up the tournament on a whopping 10/11, a score only comparable to Krush's 8/9 in 2010 and 2013 or Zatonskih's 8½/9 in 2009. The numbers speak for themselves.

The teenager will take home $25,000 after playing her last round game against Carissa Yip. Second and third places are still up for grabs as Zatonskih, Tatev Abrahamyan and Annie Wang are separated by a point before Sunday's final round.

In five out of the eight wins she achieved in Saint Louis so far, Yu had the black pieces. In her showdown against Zatonskih, she chose a fashionable line of the Slav Defence, the same one she had used to draw Annie Wang in round five of the tournament. Pressed to win at all costs, Zatonskih played 17.h4, weakening his king's shelter, before securing the queenside with 17.a5. Later in the game, White's kingside fragility allowed Yu to hit decisively:

The videos on this DVD give White a repertoire with concrete variations against all main lines Black can play and also show the typical strategic and tactical ideas of the Slav and the hidden subtleties of the position.

After 30...♝f2 White is completely busted. The game continued 31.♕d2 ♝xg3+ 32.♔xg3 ♛c7+ 33.♔g4 ♝e6+ and White resigned with mate-in-two on the board:

The king is doomed.

In the post-game interview, still nervous after getting the title, Jennifer confessed she never expected to win this game:

I actually didn't think that I would ever win this game, and I'm not just saying that because, you know, just for the sake of saying that...I was just hoping not to lose.

She still could not believe what she had done:

Maurice Ashley: Has it sunk in yet?

Jennifer Yu: I don't think it ever will.

Caruana catches the leaders

Rating favourite and number two in the world Fabiano Caruana said he "wasn't displeased" when he saw his round ten rival, Aleksandr Lenderman, had prepared the Petroff. Black went for a position with doubled d-pawns in which, according to Fabiano, "White was on the better side of equality".

Lenderman had a big advantage on the clock — like he did all throughout the event, like Jennifer Yu and Caruana stated at their interviews. His hasty play, however, led to some positional inaccuracies which allowed Fabiano to show his class, slowly improving his pieces until pushing his opponent to give up an exchange:

A World champion's guide to the Petroff

The great popularity of the Petroff Defence at the highest level has attracted general attention as strong players employ this opening with great success and with both colours. Unfortunately, the opinion of the Petroff as a sterile drawish opening seems to be firmly implanted in many minds. The author tries to dispel these myths and examines the most popular lines and provides a large number of ideas that will enable you to play Petroff successfully, with either colour.

Black does have the pair of bishops but his position is lacking coordination, while White has the safer king and a clear plan to keep advancing his b-pawn. Under these worrisome circumstances, Lenderman went for 39...♜xd4 — after only two minutes of consideration — and had little to no compensation for the surrendered material.

On move 45, Aleksandr gave up another exchange and found himself in a resignable position shortly afterwards:

The simple 47.♖c1 was the last move of the game.

The big clash of the day saw Leinier Dominguez using a very solid approach with the black pieces against Hikaru Nakamura. Given the great form shown by Leinier in Saint Louis — particularly in technical positions — we cannot blame Hikaru for choosing not to push his luck against the Cuban-born. The game ended in a repetition after 29 moves.

Master Class Vol.4: José Raúl Capablanca

He was a child prodigy and he is surrounded by legends. In his best times he was considered to be unbeatable and by many he was reckoned to be the greatest chess talent of all time: Jose Raul Capablanca, born 1888 in Havana.

The other decisive game of the day in the Open saw Timur Gareyev get his second win of the tournament, this time against Ray Robson. True to his style, Timur pushed 10.g4, although it must be said that this was a positionally justified decision. Ray did not react actively enough to his rival's approach and found himself in a losing position rather quickly:

Feel free to move the pieces on the diagram above

Only the c1-rook is not directly pointing towards the black king, so it should not surprise anyone that White's attack after 23.♗xf6 is winning. Robson needed to respond with 23...♝xf6 in order to keep the fight going — albeit in dire conditions — but his choice of 23...gxf6 allowed Gareyev to show mate on the board: 24.♗h7+ ♚g7 25.♘xe6+ fxe6 26.♖cg1+ (the rook joins the onslaught) ♚f7 27.♗g6+ and Black resigned:

Finally clear attacking plans against the Scandinavian, Pirc, Alekhine & Co! Let Daniel King show you how to pressurize these openings right from the start, forcing your opponents into mistakes.

Mate will follow with 28.♗e8#.

Final round pairings

With Wesley So a point behind the co-leaders, only a miracle would allow him to catch up and reach a four-way playoff, so it is safe to say that one of the three on 7/10 will end up getting first place. Nakamura and Caruana will have the black pieces against the only two players that stand on an even score, Jeffery Xiong and Sam Shankland, respectively. Let us not forget that Xiong had a great start this year and Shankland is the defending champion.

Meanwhile, Dominguez has the white pieces against the unpredictable Gareyev, a player that has lost no less than five times in Saint Louis. When asked about this situation, Caruana accepted that he and Hikaru will be glad to reach a playoff as Leinier does have the better chances on Sunday's final round.

If Dominguez wins, the U.S. Championship will have six different winners in the last six editions. Gata Kamsky was the last one to "repeat", as he got back-to-back victories in 2013 and 2014.
