I have an idea that I think would be helpful if you should be so kind as to
perform it.

Write a scanner that reads your wonderful EGTB files and spits out a two bit
state only for each position (won/lost/drawn/broke) to create bitbase files.

The reason I suggest it is that a bazillion programmers won't have to reinvent
the wheel.

I suggest the use of the bitbase files early in the search (completely pulled
into ram) and then EGTB at the leaves if the bitbase indicates it is worthwhile.
