All of my 2v16 records had been ready several days ago, but later I found our new theme for KPv16. Although today's work seems valuable, I don't want to delay the release.
Even if I don't quite get, why it has to be today, if you need a rather reliable result asap, I'd rather go for the .pgn but for the output after Backward:

Anyhow it should be something between 65 and 70 I'd say regards...

Er, because today is an important day, not only for me but also for someone else, in the final analysis, for my personal reason.

BTW, since we've already known the exact DTM is around 65, can we use Chest to get it more quickly?

So even only 63 or less (to be feared, there could be detours before 22nd too) regards

it takes a lot of time as it seems...i did not forseen this...this will going to be the longest research i ever made probably....i will answer when Chest has finishehed probably....i hope so...this is going to get a " defenbder-moove"...im going to expect sth like this: every move by the King draws, and everything else looses...lets see :-)

yes, the most intresting thing that i could observe is probanly this: i think its importantat that white can visit f6 because of Kh8, and its probably not possible to get him to h4...when the pawn on e7 (f6 is covered) takes this sqaure away i could not find this "very way" to make it work....its just insane to find it with having f6;-)...just a tiny view of sight :-)

but this is only an impression and even if its not a mate in 60- ...it tells nothing :-)

good night

So yet 63 all in all?
1.Kxe1 2.a4 done before your #62 counting in .pgn, 2.a4... already as first move of DTM and the Chest- parameter was Defender Moves?

Won't make you start it all over, but these 3 more plies should have been possible to be solved yet too, shouldn't they?
Of course there are some more moves to be computed instead of 1.Kx, yet they all should have short lines of denial regards

My only question is, are the winning lines from Chest 100% accurate?
