If following couple of the Comments on CVwIC, Abdul-Rahman, for a good game it is essential to use the second section recommendation of Ralph to have only ''some inverse capture pieces on the same board as normal pieces.'' And my 29.October recommends specifically Knights (for 10- or 11- or 12-square), but any one piece-type is ''more natural in not having to interpret each piece's ability changing as they do by position with each move.'' So, definitely forget about Pawns, they would be ridiculous though presented by Ralph in the pure form SimpleICChess. Pawns are omitted in most of Rule Number 25 options in ''91.5 Trillion...'' recently for this Mutator. Supposing only Knights have Inverse Capture ability enhances only Knights, and that is plenty. So there would be no interest in weird three-piece endgames of the full form. The article, it is true, is like 'Multiple Occupancy Miscellany' (and many other 'Betzas') in apparently being of diverse subject matter, and the Immobilizer, Gorgon, and Medusa are equally important here to Inverse Capture. The connection Ralph makes is at the 4th section: ''Basilisks have a gaze that turns things to stone, while Gorgons turn you to stone if you see them. This is the difference between direct and inverse capture,'' writes Ralph. So the article is potentially about everything inverse or inversion loosely. (Or would 'converse' or 'complement' be better? We understand from the context though it is not exactly the mathematical definition.) Betza gets as far as including Deferred Effects, Immobilizing reversals, and Capturing 'inverses'. This article could well be called 'Inverse Chess' instead. Time spent on it is because it is one of 50 Betzas better than current fare in being more than conventional writing up of one particular set of Game Rules as all-important followed by touting how good the game is. Most rules sets do not get played anyway beyond the scripter. Rather, here it covers a field of Chess on theme of Inversing.
