Hi Jason, Just saw this. It's funny, I was in Poughkeepsie myself around that time for college and remember driving by that big IBM facility. I'm wondering though if there could be a nomenclature issue re: Deep Blue? I did some digging on this and Kasparov seems to have beaten some incarnation of Deep Blue on 17 February 1996. He even wrote about it for Time. This article http://time.com/3705316/deep-blue-kasparov/ runs through the chain of events leading up to Deep Blue's eventual victory in 1997.
