Hello, I am having a look at UCI, both from engine and GUI point of view. A few questions: - pseudo-standard options Any commonly-used options other than the standard hash/TB/ponder ones? I am interested in options used by both engines and interfaces. For instance an interface might "provide" a WB-specific option like "random" (Jose does this). Also some engines might use identical options, making them easier to use. - "position" command Do all interfaces always send all moves (not just the ones after the last conversion)? Many engines require this? For book learning? - "info seldepth" My guess is that this was designed for engines that have a selective search between the main search and the quiescence one. Few engines do that I think. Wild guess about what depth xx/yy means in practice: do most UCI engines report the maximum ply depth reached during a search (length of the longest line)? Any use for that apart from showing off? :) - "info score mate <moves>" What is "moves"? Is it in plies so that even/odd indicates mated/mate? Or some signed full-move number? What does Chest do, must be the reference? :) - "info string" How does this appear in typical interfaces? Harmless text window or annoying pop-up? Some examples of additional infos sent by a few engines, probably using "info string"? Thanks, Fabien.
