I wouldn't find it so surprising if eventually the 20 or 40 block networks develop a set of convolutional channels that traces possible ladders diagonally across the board. If it had enough examples of ladders of different lengths, including selfplay games where game-critical ladders "failed to be

How do you interpret this quote from the AGZ paper? "Surprisingly, shicho (“ladder” capture sequences that may span the whole board) – one of the first elements of Go knowledge learned by humans – were only understood by AlphaGo Zero much later in training." To me "understood" means the neural

Hello all, It is known that MCTS's week point is tactics. How is AlphaZero able to resolve Go tactics such as ladders efficiently? If I recall correctly many people were asking the same question during the Lee Sedo match -- and it seemed it didn't have any problem with ladders and such. In chess
