S-Chess back-rank drop is good idea, but conflating the vacating and the drop in one move is bad idea. So these comments just ignore it to now, otherwise adhering to the S-Chess pieces and board. Drops from Shogi to Pocket Mutation are individual stand-alone moves with few exceptions. Technically the revision to require postponement of the drop to the very next move after piece leaves its array spot amounts to ''subvariant,'' and S-chesses could play well enough either way with better off-board piece-types. It actually makes more conservative the S-drop-mechanism to split into two moves. The author analogizes his proposal, making the drop part and parcel of the exit, to Castling. That way makes Castling itself with a drop tantamount to a triple move, which is too extreme for Chesses not deliberately plural-move category. The original S-Chess Castle with Hawk drop of the inventors means ''King slide, Rook slide over, Hawk drop,'' a three-mover. No way, too radical any prospective Track One, so under discussion only here are the revised natural first move of any piece, then next move optional drop to the piece's departure square instead. Look at other CV works having drops. Para-Xiangqi is Black's design with drop restriction by special piece's needing to be present. Follow-up will examine those drop-cvs of Winther and Nelson.
