This is Stockfish 1.7.1

You can download sources + binaries + Salvo Spitaleri's new
official book from:

This version is 100% functionally and speed equivalent with 1.7 so NO
ELO CHANGE and DON'T NEED TO RE-TEST if you have already tested 1.7


This versions removes the new and broken Hyper Threading detection
code and falls back on the well known 1.6.3 behaviour regarding
counting the CPU you have in your machine.We want to stress that you
can _always_ override what SF found by setting the correct value of
"Threads" UCI parameter to the number of physical cores of your
computer.

This version works around an issue in zugzwang positions where 1.7
fails to detect zugzwang. To avoid to break compatibility with 1.7 we
have NOT fixed the issue by default, but we have added an UCI
parameter called "zugzwang detection" that is OFF by default and when
set to on makes SF to correctly detect zugzwang, this could alter ELO,
although not more then 1-2 points, but because we want 1.7.1 to be
100% identical to 1.7 we have disabled this by default.


In the next future version this option will be removed and "zugzwang
detection" will always be enabled."


Marco, Joona, Tord
