Malcolm Pein on…Drawing the Poison
Nils Grandelius regained the lead of the Tata Steel Masters by demolishing Candidate and world number five Maxime Vachier-Lagrave. Sweden’s number one boldly took on the Poisoned Pawn variation of the Sicilian Najdorf. Grandelius is the only player on 3.5/5, with four players on 3/5, but there is along way to go in the 14-player all-play-all.
The other six games were drawn, with Magnus Carlsen held by Alexander Donchenko, who was a last-minute replacement for Daniil Dubov. The German GM navigated a complicated struggle with what commentator Peter Leko on Chess24 described as ‘perfect play’.
Grandelius’s 15.Bb3 was a novelty. Caruana defeated MVL with 15.Bc4 at Norway Chess
in 2019, but defences were subsequently found. The main line is 10…Nc6 11.fxe6 fxe6 12.Nxc6 bxc6 13.Be2 Be7, when 14.0–0 0–0 15.Rb3 Qc5+ 16.Be3 Qe5 17.Bd4 Qa5 18.Bb6 is a draw, or 14.e5 dxe5 15.Bxf6 Bxf6 16.Bh5+ g6 17.Ne4, as most recently seen in Karjakin-Duda, chess24, 2020. MVL tried to hard to win. After 19…Nh5! 20.Rf5 Nf6 White has nothing better than a repetition of moves.

31…Bf8 (31…gxf5 32.exf5 Qxf5 33.Ne7+ wins and if 31…gxf5 32.exf5 Qe8 33.Ne7+ Kf7 34.Nxc8 Qxc8 35.Qxh6) 32.Rf6! Qe8 (32…Nxf6 33.Nxf6+ Kf7 34.Qxh7+ Bg7 35.Ng4 Rg8 36.Nh6+ wins)
