In dobutsu shogi, the usual starting position is a loss for the beginning player in (at most) 78 turns (from first move until (and including) lion capture or ascension).

But are there perhaps other (starting) positions that are farther from win/loss than the standard one? I would be most interested in positions with all (starting position) or most of the pieces on the board and on the back rank.

  • If you can argue this is a chess variant, then the question should be reopened, in my opinion. – Dag Oskar Madsen Jan 18 at 15:31
  • @DagOskarMadsen, my reasoning is that it is a small-size variant of Japanese chess with very few rules changes. Therefore it must itself be a chess variant IMO, but I do not know if that was the reason this question was closed. Although it seems, it has already been reopened. Thanks? – hkBst Jan 18 at 15:54
  • Perhaps you could migrate this to Puzzling, Math, or some other Stack Exchange? It doesn’t seem like anyone will answer this here and it mag requiren computer work and lots of brute forcing. – Rewan Demontay May 22 at 19:43

The following starting position is a win in 123 (according to the software I am using):

1. setup S/cel/---/---/CGL/eG
1. show board
1|cel| e
2|   |
3|   |
4|CGL| *G
1. show lines
Gb4-b3 : #123  (100.00%)
G  *c3 : 0     ( 0.00%)
G  *b3 : 0     ( 0.00%)
G  *a3 : 0     ( 0.00%)
Ca4-a3 : #-102 ( 0.00%)
Lc4-c3 : #-44  ( 0.00%)
Lc4-b3 : #-44  ( 0.00%)
G  *b2 : #-20  ( 0.00%)
G  *c2 : #-16  ( 0.00%)
G  *a2 : #-16  ( 0.00%)
