That technology's name? Vladimir Kramnik.
At the time DeepBlue beat Kasparov, Kasparov was honestly still probably better than the computer. He just had a bad match. That was basically demonstrated by his and Kramnik's matches against presumably better computers (than DeepBlue) in the early-to-mid 2000s, which ended in draws. But Kramnik was also a strong competitor to Kasparov in the late 1990s into the 2000s.
