Thanks! @Alayan-stk-2 maybe time for another RT? |

5 gainers/8 patches is less than usual, but I guess with noob cores on fishtest it doesn't hurt, and two weeks isn't unreasonable either. I'll start them. |

This patch makes it dependant on count of passed pawns of strong side instead of 22/64 in every case.
This is reintroduction of this dependance that was simplified away approximately a year ago - since then a lot of things were changed including code of passed pawns.
