Yes, saw it, yet still I have to understand fully how to force the King to 8th rank before.
Have to have more playing and less posting, as it seems
:)
its easy to make your engine aware how it goes and then try to understand it...u and me had the same thoughts at the same time but u forgot about it ;-) : remove the f4 and h4 pawn....take my maneuvering and solve backwards and your engine can help u :-)

Not quite that, I'm only just not convinced by myself, as long as I can't convince the engine as well.
Next one point of 0.00- return of engine- eval is 24...Kb7 (positive) and 8th rank is as well as reached, but how about 24...Ka6 instead? Whenever Black has a chance to stay on a- line with the King, it should do so, I'd say. Same thing with 1st rank, don't see any pseudo- stalemate at 1st rank, neither at a-line.

Will be back, when I can get at least a winning or positive eval at starting position again.
Anyhow I'd like to stick to this first one instead of trying several slightly different ones with same theme to start with all over again.
:roll:
Peter.

I'm even less sure than I was yesterday. E.g. at your line, what forces Black to 26...h4?
How about ...Kb8 instead?

I see that you can force zugzwang with "but- one- stalemate" at 8th rank too, but I still don't see how Black's forced to get there for sure neither.
I'll wait for Hobacle to decide for a certain starting- position and an according winning line of his now regards
after 26...Kb8?!

I'm even less sure than I was yesterday. E.g. at your line, what forces Black to 26...h4?
How about ...Kb8 instead?

I see that you can force zugzwang with "but- one- stalemate" at 8th rank too, but I still don't see how Black's forced to get there for sure neither.
I'll wait for Hobacle to decide for a certain starting- position and an according winning line of his now regards
after 26...Kb8?!

Thanks, that's not the point to me anymore now, SF was able to show me this one already after Backward to it.
Now I (with the Fish) get stuck at 24...Kb7, how about 24...Ka6 instead there?

Edit, edit, edit: forget about this one too, yet already too late for Black anyhow, as it seems.
I really should sit on my fingers now for a while as long as I'm not sure about the whole thing on my own

thats a job for your hash-filled 2nd engine with f4/h4 pawns removed position...this engine is already terminated here...i try to ask my main engine ...

The first one, in my work, is easier to get a win. Just by forcing Black Pawn to move by locking Black King in h1 corner, then the position is simplified.

Not sure. The 2. ... Kg3 variation is about how to keep Black King away from h1 corner.

Haha, that's what I did and do here now and then too, second one engine is Sting (Lazy King Eval and very little Nullmove Pruning), third one is BlackDiamond (Fortress Detection).

Anyhow, forget about 24...Ka6: 25.Bc6 Ka5 (...Ka7 26.Kb5 ) 26.Bb5 h4 and it costed only these few moves as for DTM, there I have 97 now too btw)

And maybe it's really as "easy" as this:

Holding opposition with King, cutting off the directions of the opponent King to the further away one of two "bad lines", (1st rank and a- line vice versa) with the Bishop, leaving the other nearer one to it as long as the according edge of one of the "good ones" (h- line and 8th rank) crossing the bad one isn't reached. Then a pseudo- stalemate arises at h-line or (before) at 8th rank forcing a Pawn- move.

Hope there won't be any collisions with h-Pawn getting chances to promote supported by own King yet still maybe.

If I won't come back with further questions, take my acceptance of your lines and my thanks for your patience regards
Peter.

Re: A questionable position

Post by Spliffjiffer »

no sucess unfortunately, either my analysis was wrong or the 26.:.Kb8?! request ruined my hashtables...cfish gives flat 0.00
from my pov it would be probably 24...Ka6 25 Bb5 26.Ka5 and now 27.Bd7 !? or 27.Be8!?

edit:
no, 27.Bc6!? seems to be the better move instead

from my pov it would be probably 24...Ka6 25 Bb5 26.Ka5 and now 27.Bd7 !? or 27.Be8!?
Hash- ageing, as important as it is in game playing, is especially at horizon- hash- boundaries at Backward one of the big problems to keep eval- fixing plies in "sight".

As already written above, try after 24...Ka6 25.Bc6! (not Bb5? as in your line), the waiting- move with the Bishop seems to be crucial here (for the fastest cont.)
After 24...Ka6 Bc6 25...Ka5 then makes the King trapped at once with 26.Bb5 (now it's time) and Pawn has to move, and
25...Ka7 26.Kb5! and black King has to go to 8th rank again with 26...Kb8 and we are in main line with 27.Kb6 again, or instead of ...Kb8 a Pawn move at once is as short as before again.
Hope I could help from my side and return your favors this time
:)

Edit edit: what a pity, you found Bc6 on your own already again as I read in the edit of your post I answered to in the meantime.

The first one, in my work, is easier to get a win. Just by forcing Black Pawn to move by locking Black King in h1 corner, then the position is simplified.

Not sure. The 2. ... Kg3 variation is about how to keep Black King away from h1 corner.
If the first one was as easy as that, it wouldn't be any problem to keep the winning lines in hash at Backward.
Have a look at Spliffjiffer's line how long it takes, if Black's King doesn't choose h1 voluntarily to escape to but the opposite side of the board.

As for the third one position, it's the same as for the maneuvres of course, I made your 2...Kg3- variation you're doubting as long as necessary to force a Pawn- move after King escaping again towards a8:
