You can store a bitboard for western chess perfectly with 64-bit integers. Some other chess variants(like Chinese Chess, or Shogi) need 128 bits for the same techniques, since the board is larger. I haven't used it, but Julia lets you declare any(?) fixed size bitset. Which would probably come in handy for Go.
