I looked again the game in which AlphaZero sacrifices a knight on h6.
I donít believe this is brute force calculation so it makes what AlphaZero did even more impressive!



can you post the game or position

In this position, instead of Ng4 to try to save the knight, AlphaZero played Re1 and went on to win a mindboggling game.

[Event "AlphaZero vs. Stockfish"]

[Round "1.10"]

Ra8 Nd6+ 48. Kd5 Nc4 49. Rxa7 Ne3+ 50. Ke4 Nc4 51. Ra6+ Kg7 52. Rc6 Kf7 53. Rc5
Ke6 54. Rxg5 Kf6 55. Rc5 g5 56. Kd4 1-0


I tried this position with SF8 dev, Re1 move giving up Nh6 is also considered by SF8 in a multi-PV analysis.


so it can see 16 moves ahead to equalise ?
