He is a magnificent and careful programmer. He obviously puts a lot of effort into making things correct. He has a lot of insight to pick out what is important and concentrate on that. His search is excellent and innovative. He does some things that nobody else does. I'm not really sure how he is able to not hash the PV and still have a stupendously fast search, but that is pretty amazing. His evaluation function is also very different from other evaluation functions. He pays a lot of attention to control of the board. But it's kind of like asking "What makes Einstein so smart?" or "What makes Michael Johnson so fast?" When you are talking about the best in the world at anything, you are talking about a peculiar kind of genius or at least something several standard deviations away from the norm. It takes a pretty smart person to write any sort of a chess program. To make a world champion program in a short time frame takes a sort of freakish excellence that you see only on very rare occasions. IMO-YMMV.
