The opening of game 62 (7 komi, NZ rules) looks so alien and yet beautifully balanced. By move 112, black has at least a 20-plus-points lead in solid territory (diagram below by Clydevil, ~2d). Move 120 is a casual 7th-line shoulder hit. At move 186, white is about 16 points ahead. I think around move 145 is where black starts wasting ko threats. https://online-go.com/demo/view/730096

In game 64 (7 komi, NZ rules), black takes four corners. To this 13k human, throughout the game it looks like white can't possibly have enough, but of course it's a super-close game as always. By move 233, it's clear that black is ahead by two points. Move 242 is when white starts wasting ko threats. Eventually black wins by 14 or 16 points. https://online-go.com/demo/view/738197

Game 64 will be the last 19 x 19 game I've played for a while. Our tally at this point is 11 black wins, 24 draws and 29 white wins.
