Just tried it, and it's proven completely useless. Result after 500 games in 6"+0.1" (average NPS on my hardware around 1M)
Code:
Score of test vs DiscoCheck 3.5.1: 152 - 149 - 199  [0.50] 500

I wonder if it's normal, and if others have come to the same conclusion, or if I'm doing something wrong.

Basically I'm doing a verification search at high depths (depth >= 7) when the null move fails high.


Verification search need big depths to be effective. I doubt that your engine reach more than 6-7 depth in the middle of the tree (13-15 depths from the root) at such fast time control.
