Struct shakmaty_syzygy::Dtz
[−]
[src]
pub struct Dtz(pub i16);
Distance to zeroing of the half-move clock.
Can be off by one: Dtz(-n) can mean a loss in n + 1 plies and Dtz(n)
can mean a win in n + 1 plies. This is guaranteed not to happen for
positions exactly on the edge of the 50-move rule, so that this never
impacts results of practical play.
| DTZ | WDL | |
|---|---|---|
-100 <= n <= -1 | Loss | Unconditional loss (assuming the 50-move counter is zero). Zeroing move can be forced in -n plies. |
n < -100 | Blessed loss | Loss, but draw under the 50-move rule. A zeroing move can be forced in -n plies or -n - 100 plies (if a later phase is responsible for the blessing). |
| 0 | Draw | |
100 < n | Cursed win | Win, but draw under the 50-move rule. A zeroing move can be forced in n or n - 100 plies (if a later phase is responsible for the curse). |
1 <= n <= 100 | Win | Unconditional win (assuming the 50-move counter is zero). Zeroing move can be forced in n plies. |
