That was from 2017 1v1 bot. OpenAI Five apparently learned it on its own. From: https://blog.openai.com/openai-five/ https://blog.openai.com/openai-five/ > Creep blocking can be learned from scratch.

One of our team members left a 2v2 model training when he went on vacation (proposing to his now wife!), intending to see how much longer training would boost performance. To his surprise, the model had learned to creep block without any special guidance or reward.
