@RBY- those are basically the same descriptions that Wikimon gives, save for Tekken Seisai, but that literally translates to "Striking with Fists", so it's not that hard to imagine. The only one that may be an issue is Chabudai Gaeshi, as there's no real automatic restriction on how large the area is, unless it's implied that it's scaled to what is a proper chabudai table to Gankoomon. In which case, it's reasonable, if not underwhelming, seeing as they seem to be four person sit-on-the-floor tables.
