MAGNUS Carlsen survived an almighty comeback from Wesley So in their quarter-final match at the Goldmoney Asian Rapid on Chess24.
Having taken the first set, Carlsen won the opening game of the second as Black, then went 1.5-0.5 ahead, only for So to take the match to a tie-break after winning games three and four.
So converted a double-rook endgame with an extra pawn and Carlsen was unable to defend another endgame, a pawn in arrears.
M. Carlsen – W. So.
White had to activate the rook with 55.Ra7 and if 55…Rg4 56.Ra8! e4 57.Rf8, or 56…Rg1 57.Re8 Kf5 58.Re7 g6 59.Rf7+ Ke4 60.Rf6, or 56…Kf5 57.Rf8+ Ke4 58.Rf7 when White is just in time, i.e. 58…Kd3 59.Rxg7 e4 60.g6 e3 61.Rd7+ Kc2 62.Re7 Kd2 63.g7 e2 64.Rd7+ Ke1 65.Re7.
After 55.Ra7 Kf5 56.Rxg7 Re3+ 57.Kg2 Kg4 58.Re7 Kxh4 59.g6 draws.
55.Kg3? Rg4+! 56.Kh3 e4 57.Ra7 Rf4 58.Re7 Rg4 59.Ra7 Kf5! 60.Rxg7 e3 61.Rf7+ Ke4 62.Re7+ Kd3 (With his pawn on g5, not g7, White is lost) 63.Rd7+ Kc2 64.Re7 Kd2 65.Rd7+ Ke1 66.Rh7 Kf2 67.Rf7+ Ke1 68.Rh7 e2! 69.Rxh5 Re4 70.g6 Kd2 71.Rd5+ Ke3 0-1
Carlsen recovered immediately, outplaying So in both games of the blitz play-off, only forcing a draw in the second to progress 1.5-0.5.
In the semifinals, Carlsen faces Levon Aronian, who also needed a play-off to get past tournament sensation, 17-year-old Arjun Erigaisi. Ding Liren faces Vladislav Artemiev, who proved far too good for Anish Giri.
Ding drew the first set 2-2 with Jan-Krzysztof Duda, then lost a wild opening encounter in the second set.
However, the Chinese number one won the next three games, the final one being especially brutal.
