Polina Shuvalova is clearly a much stronger player than what her rating suggests. She is rated 2412, but she has already won the gold medal in the World Youth under-18 girls twice, the second one was just ten days ago. Now she seems to be all set to pick up another title. And what is impressive is the way she garners her wins. Dominant play with excellent understanding of the opening, always trying to think about opponent's plans and stopping them, and ruthless ability to finish off a game. The last one clearly points to her tactical vision. Her queen sacrifice from the World Youth against Anna Afonasieva will go down in many tactics manual.
In this position Polina sacrificed her rook on g7 with 31.♖xg7 and then after 31...♝xg7 followed it up with a queen sacrifice 32.♕xh7!! ♚xh7 33.f6+ and the king was dragged out of his hiding and checkmated on h3!
After the World Youth when Shuvalova won the gold, we asked her, "Is the gold medal more special or this combination?" With a smile on her face she said, "I have to say it's the combination!" And one would imagine that to create something like this would take many years. But Shuvalova, is in a hurry to create brilliancies! She sacrificed her queen once again, this time in the eighth round of the World Junior Championships 2019. Here's how it went
Before the queen sacrifice, there is always something else to sacrifice for Polina! So how did she begin?
In this position Polina began with 43.♗xc5! The bishop has to be taken and after 44.♕xe5+ Black has to play 44...♞g7 (44...♛g7 is met with 45.♖d8+).
What next? White to play.
Of course, a queen sacrifice! 45.♕xc5! Assaubayeva went back 45...♜b8, but that led to a lost endgame. Instead, if she had taken the queen, it would have led to a picturesque mate.
46.♖d8+ and now after 46...♞e8 47.♖xe8 ♚g7, it's a pretty mate.

Polina not only speaks about her win but also the secret of her nail polish!

With his win over Praggnanandhaa in round 8, Miguel Ruiz has joined Evgeny Shtembuliak at the top! | Photo: Amruta Mokal
Praggnanandhaa usually sticks to his main openings. But in the eighth round, he decided to try something new in the Sicilian. Pragg didn't face any issues in the first few moves as he got a relatively fine position out of the opening. However, the real problems began somewhere in the middlegame where the lack of experience of handling such positions clearly began to show.
The move 8...♜b8 is not a common one here. Black usually plays 8...♛c7, forces 9.f4 and then goes 9...♛b6. The move 8...♜b8 hasn't been played by any strong player above the Elo of 2300. But Pragg had analysed it and decided to give it a go.
Ruiz's handling of the position was quite good. He developed his pieces normally and ensured that he didn't fall for any tactics that were prepared at home by Pragg. The critical mistake came on move 19.
Pragg should have played 19...♜f7 instead of 19...c5. The point is not so easy to understand when the position is new to you. White's main idea in the position is to play 20.g4 and sacrifice a pawn. After 20...♞xg4 21.♖hg1, if you hadn't played c5 then you would have the option of 21...♛e3+. In the game c5 was played and after g4 White's attack was just too quick.
