zamar wrote:Another possibility is that Stockfish search tree is too highly imbalanced which seems to work well in most middlegame and endgame positions, but which can have disastrous effect in KNBK where optimum search tree formation is quite homogenous. Ironically low depth searches may work better than high depth searches where all moves may seem like equal.
Still it's possible that it's only a bug.
I don't know what it could be either. All moves seeming equal is certainly right, with high depths Stockfish has trouble seeing the difference in the distances to the won positions or something, like a problem with Win distance pruning which I think does not exist, but the same as in mate distance pruning. Maybe it actually is a case of the effect Harm Geert described?
For instance this position from Uri's game, in 16 move multi-PV, Stockfish 1.7 Mingw compile, one thread on single core, all moves seem to get almost the same score but several are suboptimal, like the actually played Kf1. They don't throw away the win, but lose one or two tempi which over the course of the endgame means it can't win anymore before the 50 move rule goes into effect. The move order almost is randomized.

This is with 16 moves of 22 possible moves but I suspect all moves get approximately the same eval somehow except Bc4 which loses the Bishop. Optimal are Kf3, Ba2, Bg4, Bh3, Bc8, Bf7, Bg8 M+29 and the others are 8 X M30, 3 X M31, 3 x M32. Four of those M31 and M32 are still among the top 16. but the moves all getting the same score is the most significant thing I think, if you go to higher depths the score rises a bit but still all the moves get at least approximately the same scoring as if everything transposes to the same postion.

Above in the 32 ply result the second move searched I think 15. Kf3 finds a small improvement lifting the eval to 77.27, all other moves after that profit from it by some form of transposition with the result that the 31 ply PV move 15. Ke1 ends up at the bottom of the stack as only move with 77.12, just above 15. Bc4. You still see 15. Ke1 in this list because at that moment the moves 17, 18, 19, 20, 21 and 22 had not yet been searched. Those transposition-like results must have some clue.
Next morning several plies deeper but the eval is still at 77.27, is that all from a grafted result, the added depth making no difference because it just re-searches the grafted subtree? Or a TT bug, or simply the search making no progress, or a problem with matescores faling out of the searchwindow? It could even be a rounding error with these large evals and the very small differences, Score fitting of two evals not working but why would that not be visible at lower depths. That makes no real sense, it would not cause all moves to transpose.
