In dobutsu shogi, the chick (Japanese pawn) promotes to a chicken (Gold general). In my experience this promotion occurs only rarely and I suspect after much blundering.
Does the chick promotion rule in dobutsu shogi really matter? That is, does the game really change if chick promotion is dropped (and chicks become stuck on the last row instead)?
By really change, I mean the classification of a position (winning, losing or drawing) changing, or the precise sequence of moves to force a win from a winning position changing materially.
