As a counter bot strategy, I'd work on how to break and trick it using multiple-stepped logic that an optimization function would be unable to see beyond. I'd also use varying tactics of chaotic/sporadic configurations. The bot isn't 'playing fair' nor should a human w/ intelligence. The advantage being that a human can think along a multitude of strategies and adapt. The bot is only optimizing some steps ahead.
Their 1v1 bot was defeated in this manner and it just goes to show what true intellect and superiority is. I've played random pub games w/ little to no communication and have had all other 4 players converge on different strategies based on a perception of what's going on. If someone decided to cheese/snowball, you simply wait it out and let them push themselves into a nightmare. I saw little to none of this in the games I watched which leads me to question the intelligence of said 'pros'.
