In one of the posts you linked to, Betza recommends acquiring knowledge of
Xiangqi and Shogi, which I agree with. In the other, he writes about Go,
which is a strategy board game but not a Chess variant. Neither post lends
support to any explanation for why he didn't make any Xiangqi or Shogi
variants.
