Look at the game records of Go professional Go players
In wangjinzhuo / pgd [^ 1], about 260,000 professional game record data are stored in SGF format [^ 2].
What is SGF
It is an abbreviation for Smart Game Format (Smart Go Format) and is often used to save Go game records. (Rather, I've never seen anything other than Go ...) The following is an example of SGF data [^ 2], where KM represents Komi, B and W represent black and white, respectively, and the two letters in [] represent the position.

Reading the game
You can read the game by writing as follows.
# -*- coding: utf-8 -*-
import sgf
fpath = u"All/(Kaei 2 years)1849-10-8_None_Yuzo Ota 7th Dan_None_Honinbo Shusaku 6th Dan_None_B+4 eyes.sgf"
print(fpath)
game_tree = sgf.parse(open(fpath).read()).children[0]
node = game_tree.root
while node:
print(node.properties)
node = node.next
Execution result
