64 bit or 32 bit?

Normal compilation, KLO compilation, KLO popcnt?

It varies from machine to machine you know.

In general, with those piece values, evaluation by the GUI is not precise/accurate. It shows a big advantage when it's a slight advantage that ends up in a draw. Instead of showing a realistic value it shows a big advantage.

I modified Fire1.31. to following settings:

// Search Parameters
Split_At_CN 1
Split_At_EN 0
Verify_Null 1
Null_Reduction 9
Verify_Reduction 8 //default 7
Aspiration_Window 8
AN_Split_Depth 12
CN_Split_Depth 14
EN_Split_Depth 12
PV_Split_Depth 12

// Eval Weights
Material_Weight 100
Positional ...
