You have to add the location of your Nalimov tablebases manually in the box that pops up when clicking on "Tablebase Directory..." in the options.royb wrote:Interesting. I use SCID 4.6.4 and cannot find any Nalimov TBs anywhere in the directory structure where SCID 4.6.4 "sits" on my hard drive. I was thinking maybe SCID just automatically had Nalimov TBs built into it. I don't see it, perhaps I'm just missing it.
I definitely downloaded syzygy 5 men tables and configure Stockfish to use those, but I cannot see anywhere where SCID is configured to use Nalimov TBs (which have built into them the distance to mate). There is definitely an option to have SCID use such TBs, but nothing is configured there (under Option -> Tablebase Directory) on my system. I've got nothing at all specified there (i.e. it's blank).
Interesting is that I put in this position:
4k3/8/8/8/8/8/8/2NBK3 w - - 0 1
and then ran the same Stockfish engine and get not a mate announcement but this eval: +128.51 So, somehow, with just Kings and pawns, there is a mate announcement coming, but with B+N+K vs K, no mate announcement (as expected with only syzygy bases to help the engine out).
Make sure you save the options afterwards.
You obviously have to already have the tablebases previously stored on your computer. They are not supplied with Scid.
I have had 2 minor problems in the past adding to tablebases to Scid (which I have been using for over 12 years)
1) the popup window for the location of the tablebases was behind the main window and could not be seen.
2) A more recent version than v3.5 that I compiled for linux some time ago did not support tablebases due to some copyright problem. This is one reason I have stuck with v3.5 on linux. It works perfectly for me.
My Windows computers use the slightly newer v3.61 which also works perfectly.
