Ian Nepomniachtchi: I should have created more problems at the endgame, but it was not so easy to move my pawns forward. The endgame looks maybe dangerous for Black, but probably there is a draw. #NepoDing : Anna Shtourman pic.twitter.com/nGPthhbZiU — International Chess Federation (@FIDE_chess) April 21, 2023 ALSO READ: Astana to host 2023 FIDE World Chess Championship Match The players had reached a dead draw by move 50 but Nepomniachtchi decided to test his opponent for another 32 moves. “The game started slowly, but the position that transpired on the board had a lot of venom in it. Unlike in previous games, for the first time, Ding was the one who was with some advantage on the clock early on,” reads a brief post match statement by the International Chess Federation (FIDE). ALSO READ: Former world champion Kasparov calls April’s world title match ‘amputated event’ “In the popular Berlin variation of the Ruy Lopez, the two played a familiar line leading to a mostly calm, positional debate on the board. Nepomniachtchi, who played as White, went for an attack on the kingside and sacrificed a pawn for the initiative. At one point, it started looking dangerous for Black. Ding was defending solidly and countered on the queenside, forcing White to re-evaluate his chances for a victory. Despite having to defend, it seemed that Ding was more comfortable and played with more ease than his opponent.” As the game progressed, it is noted, Nepomniachtchi made a few imprecise moves, leading to a mostly even position. They then proceeded to simplify the position by exchanging heavy pieces, White regained his pawn and the two reached an even position. In the end, Black conceded a pawn to solidify a drawn rook and knight endgame. Ding Liren: I thought it was an easy draw but then I realised it was not so simple. I could easily get a lost position. So, I thought that maybe ...h3 is the only move to save the game. #NepoDing : Anna Shtourman pic.twitter.com/xyxR1dBEur — International Chess Federation (@FIDE_chess) April 21, 2023 “Nepomniachtchi decided to test Ding, despite the position being a dead draw. After an exchange of rooks on move 52, Nepomniachtchi had an extra pawn and was pushing in an even knight endgame. Ding was walking a thin line in his defence but managed to hold.” After the rest day on Saturday, game 10 is scheduled for Sunday, April 23, at 3 PM Astana time.
