Wouldn't it be somewhat easier to install a Crystal 4.0 of your own? I can really recommend it

The mate might be the fastest one after your 65...Bh2, after the ...Qc8 of my output- line from yesterday (with anyhow as presumed too long DTM) it might be yet one move longer.

Hi Peter,

first, thanks for your competition!

I found out (SF11ofc) after 65...Qc8:

66.Qxa5 is one move better than 66.Nxc5+

e.g. 66..Kb8 67.Nc1 Qb7 68.Nb3 Kc8 69.Qd2 Qa7 70.a5 22#

[peter]

I found out (SF11ofc) after 65...Qc8:

e.g. 66..Kb8 67.Nc1 Qb7 68.Nb3 Kc8 69.Qd2 Qa7 70.a5 22#

Or even two moves better
After 65...Qc8 again:

Yes, is good enough.

Your computer with SF11 is a BEAST for mat search.

[Spliffjiffer]

For A/B engines I'm certain there is none that can win even with 1h per move. Lc0 maybe, but again I'm really skeptical.
For humans if they can do a quick check with a helper engine on the side it's rather easy. Without engine, probably not so easy.

I feel not good how i argumented, i wanna say thx for the game that u played here and i was able to follow !
thank you for the comment above, u made,...i want to agree with you by 100%...
a really hard task for current (A/B)- engines of our days to win this pos !

plz appologize my inappropriate speaking, all the best
