Although the term 'pseudo-legal move' is standard jargon amongst chess programmers, I am not sure if it would ring a bell with the typical chess player. If this isn't the case, I am not sure if we should keep this term, or perhaps introduce another term for this that sounds less technical. How about 'valid'? A move would be 'valid' if it complied with the rules for moving that particular piece type, irrespective of whether it would comply with any restrictions on exposing (royal?) pieces to capture. A move would be 'legal' if it complies with all rules of the game.
