Thanks HGMuller for the very informative information.
I believe the Lomonosov EGT is based on DTM because it includes forced mates that go on for hundreds of moves without pawn moves or promotions. The longest I believe is a 546-move forced mate.
Many of my questions are from the point-of-view of seeking an engine which plays perfectly. Of course there's no prospect of anyone doing this in the near future. But the question of "how" is interesting to me.
As for using the existing Lomonosov tablebase for actual play, I believe it could be possible for anyone who has paid to use the resource. Although the database is huge, information related to the "position-at-hand" could be transmitted in packets. I would think the internet is fast enough to support a game with 90 min/40 moves (for example).
Nevertheless, you raise some very good points. Another interesting point is that in perfect play, most of the 7-man tablebase includes positions that may not even exist in a perfectly-played game. In other words, although the tablebase represents "perfect play", much of it may not be part of "perfect games".
It's interesting to think how chess is still so far from being solved, and yet people like you (Fairy-max), Greg (ChessV), Nicolino (Chess and a Half
), Aurelian (Enep), and others keep inventing stuff that is beyond chess!
