Talk:Openings on 19 x 19

Thanks for creating this resource. While KataHex is very strong, I think one should take its opinion on 19x19 with a grain of salt. According to its website, KataHex has mainly been trained on 13x13 (for 20 days), and then up-trained on sizes of up to 19x19 for only one day. Up-trained means that the model that was already trained on 13x13 was then allowed to play 19x19 a bit. This method of training means that like a human, KataHex will mostly try to apply whatever lessons it has learned from 13x13 to the larger boards, and then learn a little bit extra from experience.

Even with that in mind, KataHex on 19x19 is probably still much stronger than most human players, so we can learn from it. But the advice may not be very specific to 19x19. 20:38, 30 March 2023 (UTC)
