Wesley So, Praggnanandhaa Rameshbabu and Alireza Firouzja will enter the final round of Norway Chess with chances of winning the 13th edition of the super-tournament. So remains the sole leader after round nine, but his advantage has been reduced to half a point over Pragg with Firouzja another half-point behind.
The final-round pairings make the situation particularly interesting. Firouzja will have the white pieces against So in a key encounter between title contenders, while Pragg will also play white, against Vincent Keymer. With the Norway Chess scoring system giving three points for a classical win, all three players remain firmly in contention.
The ninth round, played on Thursday, again produced exciting chess and greatly impacted the fight for the title. Pragg scored his third classical win in a row, defeating world champion Gukesh Dommaraju with the black pieces. After consecutive losses in rounds five and six, Pragg has responded with three straight classical wins - over Firouzja, Carlsen and Gukesh!

So also added to his score, though he first had to defend an uncomfortable position in his classical game against Magnus Carlsen. That encounter was eventually drawn, sending the match to Armageddon. In the tiebreaker, So had the white pieces and defeated Carlsen, collecting the extra half-point and keeping first place before the last day.
Firouzja's match against Keymer was the longest and most volatile of the round. Their classical game lasted 91 moves and saw both players miss clear winning chances. In Armageddon, Keymer blundered early, and Firouzja took advantage to secure the tiebreak win and remain within a point of the lead.
The results in Oslo are having a notable effect on the live ratings list. Carlsen has lost 21.3 rating points and is now "only" 28 points ahead of Fabiano Caruana at the top. So has gained two places and moved to 7th in the world, while Pragg has climbed four spots to 12th.
Gukesh's difficult tournament has also been reflected in the ratings. The world champion has lost 11.3 Elo points and has dropped to 25th place in the live rankings. Among Indian players, he is now only fifth, behind Arjun Erigaisi, Pragg, Viswanathan Anand and Nihal Sarin.

Both contenders missed a number of winning chances in the classical encounter. Keymer had a clear positional edge in the middlegame, but the ever-fighting Firouzja managed to muddy the waters by playing a speculative exchange sacrifice on move 34.
Eventually, a position with queen, rook and two pawns against queen, knight and four pawns emerged. Keymer, with the rook, was still for choice at first, but then allowed Firouzja to turn the tables. However, Firouzja failed to find a path to victory while in the driver's seat.
In the ensuing rook versus knight endgame, Firouzja again achieved a big advantage, but a blunder on move 81 allowed Keymer to escape with a draw.
Following a tension-filled battle, Keymer faltered early in the tiebreaker - and Firouzja had no trouble converting his advantage into a win.

After putting pressure on So in the classical game, Carlsen apparently was not motivated enough to defend a difficult position in Armageddon.
White is for choice here, but it is not at all trivial to find a way to break through, given Black's solid setup. Carlsen's 28...a5?! was a bit careless, allowing 29.Qf2 followed by 30.Qa7, and So managed to effectively infiltrate Black's camp.
Under different circumstances, it is likely that the ever-pragmatic Carlsen would have found 28...Nd7, going for passive defence while playing black in a sudden-death decider. But this has not been Carlsen's tournament.
