Suppose Alabaster opens 1. Gb3. This threatens 2. Gd5, placing five Obsidian Humans under compulsion to flee (b7, c7, d7, e7, f7). After b7-a6, f7-g6, c7-b7, e7-f7, and d7-c7 or d7-e7, Obsidian still has compulsions on 3 Humans and no way to satisfy or remove any of them, and thus loses.
It appears to me that Obsidian's only answers to 1. Gb3 that avoid immediate loss are 1...Gb6 or 1...Gf6 (petrified), preventing the Alabaster Ghast from entering d5. Does anyone see another option?
