... and does so in a way that might be pretty risky to emulate, although maybe educational. In particular, playing very aggressively against white and escalating the fight repeatedly and taking many risks to try to kill things (or, at least what looks to me as a lowly amateur dan like many risks).
"masamune" is a user from the LZ discord chat who has been having fun trying to run extremely-high-playout versions of KataGo to beat "kata-bot" on OGS while giving it various numbers of handicap stones. "kata-bot" is a version of KataGo I leave running with moderate visits (max 5k) as a popular human handicap game opponent on OGS. Hence, this 3H game.
I thought this specific game was pretty fun to highlight. In particular, move 72:

Are both bots assuming they are the stronger player, i.e. with playoutDoublingAdvantage in the config files turned on with a positive value? (Assuming that I correctly understand what that parameter does of course!)
