I Made a Chess Library in Java

Nice, great to see more open source efforts on Chess. GitHub is down and I can’t quite tell what is the need you are trying to address with this library.

You need to switch your data representation to 0x88 [1] or bitbords [2] to get anything performant. You won't get anywhere with a class hierarchy

GitHub is down at the worst possible moment for me... Hopefully they'll fix it up soon

Perhaps they don’t need anything performant? You don’t need a bitboard for everything. (They’re also not always performant.)

If the API is well written, this is an implementation detail.
