Game 58 (7 komi, NZ rules) in which black develops a huge center moyo is beautiful IMO. Notable moves: 57 - So cool.
182 - After playing this move, KataGo realized that white was winning by 2 points. Black casually wastes some ko threats and ends up losing by 4 points.

The first 16 moves of game 110 (7 komi, NZ rules) look remarkably human to me. Move 69 is a tesuji and a half. By move 129, black has three corners and a large center moyo, but white makes sabaki in there and reduces it to nothing. Move 142 results in beautiful local symmetry. The endgame sees both players happily wasting ko threats, signifying a draw.

Game 133 (7 komi, NZ rules) sees both players making massive territories. Black ties his top side moyo together to live in one group. It's a draw.

In game 134 (7 komi, NZ rules), black and white each manage to kill about 20 of the other player's stones. But white's reduction of black's giant center moyo is just too much, and she wins by 10 points.

Game 135 (NZ rules, 7 komi) begins with both players tenukiing from a high-approach-to-their-3-4-point joseki. White gains a local advantage in the top left from that, black in the bottom left. In the endgame, a dispute over the top side (starting with move 185) ends with both players getting more or less equal shares (move 258). Only small endgame follows, and the game is a draw.
