That's the position after 40 moves of solution of this one of Blathy's studies

HHdbVI nr. 0798.38a3d3 gives 210 moves to mate all in all.

Can't reproduce your time at all, neither can't Olaf Jenkner, as he wrote to me per email.

But here's the main variant of solution of my installation of Gustav 4.1d with #163, 0 Fluchtfeldern, from the position of the study the thread started with, Blathy's

Hi peter.
Right now, Gustav 3.2g (f0, z9) needs 7 min 4 sec for mate in 170 moves.

Impressive
I don't have 3.2 anymore, but 4.1d with Fluchtfelder 0, Drohtiefe 9 (and or schwarze Gegenzüge 9, what's your "z9"?) says no mate in 170 found with these parameters at the position of yours.

Hi peter.
Right now, Gustav 3.2g (f0, z9) needs 7 min 4 sec for mate in 170 moves.

Impressive
I don't have 3.2 anymore, but 4.1d with Fluchtfelder 0, Drohtiefe 9 (and or schwarze Gegenzüge 9, what's your "z9"?) says no mate in 170 found with these parameters at the position of yours.

z=Maximale Zugzahl

Maximale Zugzahl means as for "schwarze Gegenzüge", there 9 and to be defined "Ausnahmen" 0 doesn't work with 4.1d (no mate with given parameters), same up to 9 Ausnahmen, how many did you set?

[Ignacio]

Sorry Peter. z17
Best,
Ignacio

[peter]

Sorry Peter. z17
Best,
Ignacio

Ok, with this setting ( schwarze Gegenzüge maximale Zugzahl 17,Ausnahmen 0) 4.1d get's the mate in 170 in 3'54"

[Ignacio]

Yes.
