Lame leaper that has to be blocked on more than 1 square?

[Yowwowwow]

I wanna implement a piece but am not sure how to. This piece moves like a king, but when moving diagonally, it can be blocked from a square if it cannot reach that square in 2 wazir moves (1st wazir move can't be a capture). For example, it cannot move to its top-right square if its right square and top square are both occupied.
How can I implement this piece? More generally, can I implement a lame leaper that has to be blocked on more than 1 square? E.g. a knight that can move from (0, 0) to (1, 2) only if at least 1 square of (0, 1) and (1, 1) is empty.
