Excluding squares from mobility

[OliverBr]

What happens if you increase the weight of mobility now to compensate the fewer squares on average?

Good tip, I tried it already with a fix factor. It didn't help. perhaps the factor was not correct, but it should have done anything.

Actually the last idea to mix the two mobility (one like before and another new one mit mobilitymask) brought something about 8-9 ELO. Probably the idea is not bad, but the now two times popcnt are not good eats most of the gain.

Code: Select all

mn += (_bitcnt(a) + _bitcnt(a & mobilityb)) << 2;

Code: Select all
