There are other more realistic examples like the Nakamura game sacrificing 2 useless rooks to give the engine a false sense of winning. Then the engine sacrifices a valuable pawn to avoid a 50 move draw. Turn out the pawn was much more valuable than the 2 rooks in the particular closed position and Nakamura goes on to win. Basically, the only way to beat an engine is to try to create an unusual situation that the AI hasn’t practiced before. But as others other out, AI suffers when it doesn’t have enough experience in a particular situation. So, the author is really just pointing out the extreme edge cases AI hasn’t mastered yet. But over time and getting these examples into the training process there’s no reason to believe that the AI couldn’t learn these situations as well.
