It is incredibly difficult to produce a tactical test suite with 1000 positions which is thoroughly debugged.
Even 100 positions is rather difficult.

For instance, what if the line is confirmed by several top engines ?

I think test suites need much more number of positions. More than 1000 for instance.

I think you can use Clang as your compiler while keeping Visual Studio as your IDE.

In xiphos SEE, one can read else if (sq == pos->ep_sq && p == PAWN) { occ ^= (1ULL << (sq ^ 8)); gain[0] = piece_value[PAWN]; } about the case where the destination square (sq) of the initial move is the ep move. Can someone explain this occ ^= (1ULL << (sq ^ 8)); , I don't get it. :oops: Thanks Th...
