Reading your recent posts has been like dipping my bottom over and over into a bath of the silkiest oils and creams.
Yes, it's the same game. This version of the game was published in The Book of Classic Board Games, published by Klutz Press in 1991, for which Sid Sackson was the "primary games consultant".
The boards look EXACTLY alike - the only difference being that Blue and Grey involve 18 pieces per side where the description for this game says it involves 17 pieces per side.
This game has 17 guards and one "top dog"/"top cat", so there are 18 pieces total.
