Studying endgames in nocheto using tablebase
Nocheto has build in a tablebase support. Tablebase is a database which contains all possible moves in endgame positions with theirs evaluation (whether they are winning, loosing or drawing). Nocheto downloads tablebase from tablebase.lichess.ovh (lichess public API).
Tablebases are disabled by default as they can slow down the nocheto drawing (and might not work if the internet is down).
To enable the tablebase, use viewtablebase (vtb) command or enable viewtablebase in the configuration.
Lichess tablebase has computed all positions for 7 and less pieces (included kings). So you can use it once you get to endgame with 7 or less pieces.
On the picture above you can see that there is only one winning move (Rb3) and one loosing one (Rc2). All other (white) moves leads to a draw position.
If your internet connection is slow, the tablebase can slow any move you or an engine does (the board is drawn after the tablebase is downloaded). You might want to disable tablebases in that case.
