In game 40 (New Zealand rules, 7 komi), white builds a center moyo. Black invades it at move 63 and claims more than half of it. Some major trades occur elsewhere. In the end, black wins by 4 or 6 points. https://online-go.com/demo/view/546829

Game 41 (New Zealand rules, 7 komi) was a spectacular, messy-looking whole-board fight. Another incredible tie, bringing our final tally of this series to 10 black wins, 11 ties and 20 white wins.

KataGo continuing from an AlphaGo Teach position, game 12: In which white almost makes a B2 bomber shape in the fuseki. Black refuses to be shown up and builds a proper B2 bomber later. The game is decided in a ko that is fought over 76 moves. https://online-go.com/review/549948

In my endeavour of exploring AlphaGo Teach positions (Chinese rules, 7.5 komi) in which white plays a mistake on move 2 to give black a closer-to-even winrate, KataGo has found a few move 2s which are not included in AlphaGo Teach’s database. This is my first pure KataGo self-play game with Chinese rules and 7.5 komi, in which white miscalculates a ko and black is ahead by about 27 points by move 179: https://online-go.com/review/578137
