AFAIK this is always GUI dependant (I'm not aware of engines themselves that
would support the Thompson data like the Nalimovs). Shredder 5 still had the
Thompson support and can use WinBoard engines via it's own adaptor, versions 6/7
probably too (?) but I'm not sure at the moment.

I don't know if there is a freeware GUI which can read these databases.

I also use the Thompson data then and when (because I don't have the 5-piece
nalimovs, only 4-piece mainly), but not in concunction with an engine. I use CB
7.0 for that, to check 5-piece positions when they have been reached in the
game. But AFAIK no engine or program can use the Thompson's nalimov-like, IOW
they are not access during the engine's calculations (earlier) in the search.

Btw. you should be aware that the Thompson data isn't always 100% reliable,
unfortunately. Not only that the data of the 4th CD edition is affected
partially (it hasn't been tested like the CD editions 1-3 have, as Ken Thompson
has explained), recently also an obvious mistake in a Thompson database from the
CD 1-3 set has been found. Very sad.

I'm sure that could be easily done by a good GUI programmer. "Replay previous
moves", number configurable. Although I guess I wouldn't use that often, as I
can go back and forth in the notation anyway. Or did you think of a kind of
retroanalytical function of the engine, not connected to the game itself? (I
probably still don't understand, but never mind...)
