as before it will run Thomas Zipproth's Cerebellum book ( fantastic book, it's worth about 30 ELO by itself ) and will feature play by ELO and other goodies, such as a UCI option to turn on most of Joe Ellis' Matefiner code , as well as a "brute force" options ( tunrs off all reductions and null move) and naturally will be based on the latest SF code and some very nice patches which the SF team will commit to in some form in the near future I am sure
and one little bit of code that will skinny down the tree incrementally as you increase the number of threads for your multi-core machine - my testing shows 10 or more ELO gain when using 8 cores or more than standard Stockfish.

my guess is that McBrain should test about 20 ELO or more higher than Stockfish 8 ( likewise current development SF would also test about 20 ELO or more higher than SF 8 I believe)
follow the results here live ( updates about every 120 games or so , about 20 minutes) : https://www.dropbox.com/s/6qd33ywphjyec ... a.txt?dl=1

I have also reduced and simplified the UCI options, eliminating some of the more technical ones relating to controlling search (lmr depth, pruning, probcut etc).
Should be released on or about May 1st with an announcement here.
