A bitbase is similar to a tablebase, but with less information.  For each
position, the bitbase says whether the position is won, lost or drawn, but
it does not give the number of moves to mate.

The advantage of bitbases compared to tablebases is that they are much
smaller.  A program can often keep the most fundamental bitbases in RAM,
which makes them very fast to probe.
