I wonder how do you know that
"zugzwang detection" cannot alter ELO by more then 1-2 points

I am sure that you did not play enough games to test it at long time control.


You are right Uri, actually I have started a regression test but after 500 games results are a bit strange and we will need to redo the test.

I said few points because the change impact is very low, I have measured the impacted nodes and is less then 1% of cases....but real games results seem to show another story and we have to better analyze it, anyhow 1.7.1 is setup to be used with default parameters by testers so that there is no difference with 1.7
