Hello Steven!

This is the thread for perft(14) estimates.

My guess: 70 quintillion. (70,000,000,000,000,000,000)

Please take a look to a thread that I started in January, where I collected some Perft(14) estimates as well as I did my own estimate averaging 400 MonteCarlo perft samples, plus my own estimate using an unorthodox method (if it deserves to be called method):

Doubt: perft estimate averaging N MonteCarlo samples.

Here is what I got after about 196 core hours:

Code: Select all

m = 6.18847822079403e+19
s = 0.00002368654103e+19

Good luck with the project!
