PW[KataGo]PB[KataGo]DT[2020-10-06]CP[Antti Törmänen]C[This KataGo selfplay was run by Attila Egri-Nagy the game was shown on his Youtube channel (https://www.youtube.com/watch?v=uwRcnMGZiKk&ab_channel=AttilaEGRI-NAGY). While I don't know the exact number of playouts used throughout the game, I remember Attila mentioning that at the most he has he has had KataGo read to roughly about 1,000,000 playouts. Supposedly both KataGos' play is very close to 'perfect'.

The motivation to both such 'perfect play ties' and this game commentary arises from the logic that, arguably, the better the game content, the more there should be learn from it (since, if you learn techniques and strategies from suboptimally played games, the techniques and strategies you learn have existing counters). However, at the same time, the higher the level of play, the more difficult it is for weaker players to make sense of it (the effect should be similar to if you try to teach calculus to elementary school children). Because of this, we have professional game commentaries that explain the content of the game in simpler terms.

The crucial point about this experiment (whether strong AI games are good learning material for humans) is whether the AI's moves and playing logic can be translated to human terms. Humans generally play go by breaking the whole-board position to smaller pieces and analysing them separately, and then finally combining the pieces back into a whole. At the same time, human players try to keep track of the existing groups' statuses and relative strengths and importances, and try to structure their play accordingly. The AI has nothing like this, and it always views the board as a fluid whole; whether this quality makes its games difficult for humans to learn from remains to be seen.

Note that the komi of this game is 6 points, allowing ties with Japanese rules.]RE[0]SBKV[52.4]

;W[pb]LB[pf:A][qf:B]C[This connection is the first of two questionable moves I can find from this endgame mainly, it seems to me like white should force A-B here, since it is his privileged sente.

In the game black got to play A instead, which raises the possibility of white A maybe being a key mistake – however, if white's response to black A in the game is similarly big, it is possible that the result is finally not affected.]LZ[0.7.2 37,9 13k

;B[js]LB[gq:B][is:A]C[This descent is a clear mistake: there is no merit this move can have over black A, which consequently increases the value of the B ko.

However, as the very last valuable move in the game went to black, it is possible that even if black played A here, that would just switch the endgame so that the last valuable move goes to white, with the final score not getting changed. Still, principally speaking, black A instead has to be better.

The rest of the endgame after this appears to be correct.]LZ[0.7.2 59,5 10k

In the following, now white may technically think about the A-B-C-D-E sequence, since the white F stone provides the necessary backup for it. However, black then simply responds with G and settles his group, with white having to come back to fix his cutting point at H. In other words, the sequence starting from A mainly only has territorial importance, and should not be played yet because this game is still in the early middle game.

KataGo would now play tenuki to I as black. Apparently this is also an even game, so the 'logical' move of J cannot be considered a mistake. Arguably, as it is difficult for humans to think of a sequence like what white did here, J might even be better in human go, as it might goad white into making a mistake.]LZ[0.7.2 50,0 0

Probably the main thing we can get out of this sequence is that, in this game, the A-B-C-D exchange doesn't cost white anything – mainly because black already has a thick position in the upper-right corner, and therefore white doesn't mind strengthening it further.]LZ[0.7.2 50,0 0
