Another idea is to split the table into two equal size tables; one for WTM, the other for BTM. I've done this and it has worked well. In a program with a variable search depth, both tables see about the same usage regardless of the root STM. Pre-determining which half of the hash table will be used...

Location of files for the Perft(14) project There are some challenges affecting the continuation of the Perft(14) project, so here are the public locations of the files needed for independent continuation if such becomes needed. The work is more than 50% complete, so it's all downhill from here. ---...

Thank you for your verification calculations.
