Carlsen – Caruana 2018, game 1
Update 16:03 CET
The game starts as Sicilian Rossolimo
Update 16:11 CET
Carlsen diverges from a previous game and goes 7… Nd7, putting the game into a long positional struggle. The new move puts Caruana in deep thought
Update 16:20 CET
A move too early Fabiano goes for short castle. Better would have been Lc0’s suggestion 9. Qd2 h6 10. O-O b6 11. Nh2 Nf8 12. f4 exf4 13. Bxf4 Ne6 14. Be3 Nd4 15. Rae1 Be6 16. Nd1 Nb5 17. c3 Qd7 18. Nf2 O-O-O 19. Nf3 g5 20. a4 Nd6 21. a5 f5 22. axb6 axb6 23. exf5 Nxf5.
Another option was SF[128] suggestion 9. Qc1 Qe7 10. Bh6 Bf8 11. a4 a5 12. Qe3 Bxh6 13. Qxh6 f6 14. Nd2 Nb6 15. O-O Be6 16. f4 exf4 17. Qxf4 Rf8 18. Rae1 O-O-O 19. b3 g5 20. Qf2 h5 21. Nd1 Kb8 22. Ne3 Qc7 23. Nf5 Nd7 24. Ng7 Bf7 25. Qe2 g4 26. hxg4 hxg4 27. Qxg4 , but that continuation is less human approach, than the suggested by Lc0.
Update 17:00 CET
After Carlsen’s 10th move, both Lc0 and SF[128] reached agreement in their PVs suggesting 11. f4 exf4 12. Rxf4. The players were also fast to agree this is the best continuation and blasted the moves on the board. Now the Neural Network fluctuates between …Be6 and …g5 with scores around +0.5. Stockfish on 128 cores has a different idea, …h6 with +0.1
Update 17:30 CET
Again agreement by the two engines at move 14 that a4 is needed. But then it gets wild, check out the proposed PVs below. Anything that is not 14. a4 will either equalize the game or turn it in black’s advantage
Update 17:35 CET
There we go, Caruana goes for 14. Qd2 and Stockfish announces 0.00 with prospects for black in most lines. Lc0, which is usually also optimistic at this stage is gravitating around the zero score.
Update 18:00 CET
Getting low on time compared to Carlsen, Caruana takes the risk with 16.Ng4. Nothing good can come out of this position, he will be defending for the rest of the game
Update 18:30 CET
19. g4 was the best move for Caruana and he found it. Yet, the eval of SF[128] is -0.84, white is still fighting for the draw
Update 18:45 CET
Now Nf8 was really unnecessary move by Carlsen, there were many better proactive decisions. Is the World Champion waiting for another blunder by Caruana?
Update 18:55 CET
Caruana immediately jumped on the opportunity and equalized the game after yet another inaccuracy by Carlsen
Update 19:35 CET
Dramatic moment in the game! Fabiano Caruana with a big blunder and if Carlsen finds 33. .. Qg5 the game may very well be over! For example 33. .. Qg5 34. Qf2 h5 35. Nh2 Qe5 36. Kd2 Rg3 37. Nf3 Qb2 38. Kd1 Qxa2 39. e5 Qb1+ 40. Kd2 Qb2 41. e6 Bd6 42. e7 Bxe7 43. Qe2 Qf6
