Manhattan Distance wrong

[Carbecq]

Same as Chebyshev distance.

Can you point to where it's wrong?

Hi, In the file bitboard.h, line 458, 485, Manhattan distance and Chebyshev are the same. Its should be this :            int vertical   = abs(SQ::rank(sq1) - SQ::rank(sq2));             int horizontal = abs(SQ::file(sq1) - SQ::file(sq2));             MANHATTAN_DISTANCE[sq1][sq2] = vertical + horizontal; I took the definition here : https://www.chessprogramming.org/Manhattan-Distance
