The problem with this research is that KataGo does not know that it is playing under TT rules, which is unfair to KataGo. If humans don't know that they are playing under TT rules, they will also "lose" to the agent. Therefore, claiming that it has won the KataGo is kind of insulting to the KataGo's authors. No human player will think that KataGo has lost to the paper's agent.

Although KataGo did use the TT rules during training, most games (90%) are judged by the win rate of the agent. Moreover, even in the games that use TT rules, the games typically have captured most of the dead stones since the losing side won't "PASS" and will keep playing until there is no place to play. Hence, it is safe to use TT rules. Therefore, to KataGo, it won't know that the states that the paper show is losing since it won't happen during training.
