Update 20:15 CET
Official, Caruana and Carlsen shake hands for a draw, the score is now 1,5-1,5. Games 4 is going to take place tomorrow, with Carlsen having white again.
Update 19:35 CET
At move 41 we have reached a complete equality 41. .. Kc7 42. Nf1 Kc6 43. Ne3 Be7 44. Kd2 Bd8 45. Nc2 Bb6 46. Nb4+ Kd6 47. Ke2 Kc5 48. Nd5 Ba5 49. Kd2 Bd8 50. Ke3 Kd6 51. f3 Ba5 52. g4 Bc7 53. Nxc7 Kxc7 54. gxh5 gxh5 55. f4 exf4+ 56. Kxf4 Kd6 57. Kf3 Kc5 58. Ke3 b4 59. cxb4+ Kxb4
Update 19:00 CET
Caruana has had several micro imprecisions. Lc0 already announced that the game is more difficult for white after move 21, however, Caruana’s play does not help that fact. After 33. c3 Lc0’s eval went down to -0.77, indicating more difficulties ahead for white. Objectively the game is still drawn. Chance for Carlsen?

Update 16:59 CET
But what is Carlsen doing? Opening up the position is risky here. Did he consider 14. Rxa5!? For example 14. Rxa5 Rxa5 15. bxa5 Qxa5 16. Bd2 Qc7 17. Qa1 Both Lc0 and SF128 evals spiked.
Update 16:57 CET
While white looks visually better, there is not much in this position. Caruana would have hoped for a better opening advantage as white.
Update 16:39 CET
There we go, Caruana prefers the second line of SF128 over the top line of Lc0 in this case, choosing to go 10. Nbd2 . Keeping the advantage of the pawn after 10. bxc5 is difficult, Caruana’s attitude in this game has been consistent so far. Again difference of opinions, Lc0 suggests 10. .. cxb4 , while SF128 goes for 10. .. Bg4, the full line here is 10. .. Bg4 11. a4 Nd7 12. Ba3 b6 13. h3 Be6 14. Nb3 Bxb3 15. cxb3 Rfd8 16. Rc1 Bf8 17. Rc4 Rab8 18. Qc2 h5 19. Rb1 Bd6 20. Rc3 Be7 21. Nd2 Bf8 22. Nf3 Qd6
Update 16:37 CET
Lc0 also suggests 10. bxc5, here is the full line 10. bxc5 Re8 11. Nbd2 Be6 12. Nb3 Bf8 13. Be3 Ng4 14. Bg5 Bxb3 15. cxb3 Bxc5 16. Bh4 Be7 17. Bg3 Bd6 18. Qd2 Nf6 19. d4 Nd7 20. Rad1 Rad8 21. b4 exd4 22. Qxd4 Bxg3 23. hxg3 Ne5
Update 16:35 CET
The Women World Championship day is now complete, with Zhansaya Abdumalik and Kateryna Lagno victorious, replay the games here
Update 16:25 CET
A very interesting difference of opinion in the analysis of Caruana – Carlsen. Engines at lower depth go with 10. bxc5, however, the high depth of SF128 prefers to wait with 10. h3, a move that it has suggested for quite a while now. Another interesting suggestion is developing the knight Nbd2, but not the bishop to Bb2, which would lead to 0.00
Update 16:20 CET
First official game of Season 14 of the Top Chess Engine Championship is now live, you can follow the competition at the official website
Update 16:14 CET
Current suggested continuation: 8. h3 Be6 9. b3 a5 10. a4 Rc8 11. Bd2 Rd8 Caruana goes 8.a3 instead, leading to one more serious eval drop. Caruana is ready for a long positional game.
Update 16:10 CET
Caruana goes for 7. Re1. Stockfish on 128 cores is not happy about the move. It is an eval drop of around 0.4, however, this is a rare opening line and probably a surprise weapon by Caruana.
Update 16:05 CET
We get a repeat of the opening so far 1. e4 c5 2. Nf3 Nc6 3. Bb5 g6 4. Bxc6 dxc6 5. d3 Bg7 but Caruana is the first one to deviate with 6. O-O instead of 6. h3. It is followed by immediate Qc7 by Carlsen. The suggestion of SF128 is 7. a4 Rb8 8. Be3 Be5 9. Nxe5 Qxe5
Update 15:30 CET
We saw a Sicilian, Rossolimo Variation in game 1 of Caruana – Carlsen that started with . Caruana went for 1. e4 c5 2. Nf3 Nc6 3. Bb5 g6 4. Bxc6 dxc6 5. d3 Bg7 6. h3 Nf6 7. Nc3 Nd7 8. Be3 e5 and then 9. O-O. If we get a repeat of the opening today, are we going to see Lc0’s suggestion 9. Qd2 or SF128 suggestion 9. Qc1 ?
Knowing Caruana’s diverse play style, he ma prefer to go for a totally different opening today to surprise Carlsen.
Update 14:15 CET
Parallel to the World Chess Championship match today you can enjoy two other major events. In Russia we have reached the quarterfinal stage of the Women World Chess Championship, you can follow it live with analysis here. Today starts also the Top Chess Engine Championship, the premier event for computer chess. It will be live after 16:00 CET at the official website
Update 14:00 CET
Today is game 3 of the match and Fabiano Caruana has the white pieces again. In game 1 (replay here) the American was on the brink of losing. The 128 cores Super Computer analyzing the game was often hitting -7 evaluation, while the neural network Lc0 believed the game is long gone before the time control. Series of inaccuracies by Carlsen saved Caruana from a disastrous start. Today he will have a chance to show what he ca do with the white pieces again.
