Mate solving test SF19, SF18 and SF11.

[Jouni]

Positions are here https://github.com/vondele/matetrack/bl ... etrack.epd . Tactics is not mate solving .

[Uri Blass]

I wonder what you consider solving.
Do you consider having a mate score but with wrong number of moves to be solving.

For example what is the time stockfish16.1 solved the position in this analysis?

1 second was enough to see mate in 31 in iteration 31
14 seconds was enough to lose the mate score in iteration 48 when the score is 0.00 but it immedaitely found mate in 31 in iteration 49
150 seconds was enough to get a mate in 30 score at iteration 60.
