Why SF is blind to certain TB draw positions

Post by Nay Lin Tun »








SF cant see draw in 8 men TB in diag 1 and 2.

However, SF can see draw in 9 men TB in diag 3.


Both ccc an Tcec have 6 men TB.

Although you refer to them as TB positions, they are not TB positions. If you use 6-piece TBs, positions with 7 and more pieces are not in the TBs.

The other half of this, is whether the game will involve simplification into something that's ACTUALLY in its tablebases... Most of the time it does, so 8-man, 9-man positions usually wind up getting an evaluation based on a post-simplification TB hit.

At least in the first diagram, Stockfish is stuck in a 7-man fortress. No matter how deep its search goes, its PV will have 7 pieces on it. So that PV never winds up using the available 6-man tablebases. Stockfish therefore must use its static eval, and apparently its really inaccurate (I think it was -9ish?) in this position.

in the first position...
[d]4R3/8/8/8/6p1/5p2/1r2k2P/6K1 b - - 0 1
Stockfish 11 scores the position as +2.08, over and over and over
this is a clue that there is a draw (fortress, probably) but SF hasn't searched deep enough to verify it as a draw through the various rules of chess (50 move, repeating positions, etc).
If SF could search long and deep enough, eventually the score would change over to 0.00.

So whenever you see the engine score staying the same, that is what is probably happening.
Some engines though can identify it as a draw rather quickly.

SF cant see draw in 8 men TB in diag 1 and 2.

However, SF can see draw in 9 men TB in diag 3.


Both ccc an Tcec have 6 men TB.
diag 2 and 3 are the same. :)

[d]4R3/8/8/8/6p1/5p2/1r2k2P/6K1 b - - 0 1
Stockfish 11 scores the position as +2.08, over and over and over
this is a clue that there is a draw (fortress, probably) but SF hasn't searched deep enough to verify it as a draw through the various rules of chess (50 move, repeating positions, etc).
If SF could search long and deep enough, eventually the score would change over to 0.00.
