Tough to set up your engine for better use of a multiple Gigabyte memory, when most computers only have 256Megs, 512Megs, or 1 Gig. of RAM, I think. :) While EGTB's may be great in memory, I'd personally like to see more AI, or planning heuristics come into our programs. As long as the search depths are entirely excellent, along with the decreasing ability for a greater depth to strengthen play, I think that more planning ability would be a great addition for the chess programs of tomorrow.
