Most of the memory is being used for the hash table and the static cache
table.  You can change these values in gnuchess.h (vtblsz && ETABLE) and
recompile again.

Alternatively, you can start gnuchess with the -T option to specify the
size of the hash table.

gnuchess -T 14 will use a hashtable of 2^14.

The size of the static cache cannot be change during runtime.
