Help save Otto Titusz Blathy (see yacpdb id 278043)

Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

[d]8/5k2/8/2Bp2pb/p1pPp1p1/1pP1PpP1/1P1R1P2/3NK2N w - - 0 1

On the above position Rd3? was played on your attached EPD file.
The correct line seems to be Re2! followed by Kd2. This line would avoid the
fxe2= variation.

Both of these positions:
[d]8/5k2/8/2Bp2pb/p1pPp1p1/1pP1PpP1/1PR2P2/3NK2N b - -
[d]8/5k2/8/2Bp2pb/p1pPp1p1/1pP1PpP1/1P2RP2/3NK2N b - -
also allow the rook to be captured by a different pawn.

I see a better score, but it also looks static.

e.g.:

Code: Select all

Searching: 8/5k2/8/2Bp2pb/p1pPp1p1/1pP1PpP1/1PR2P2/3NK2N b - - 0 1

Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

Yes. Seems to be a typo also. Because on above position, your EPD shows
Ke1? bxc2= move which can be improved with Kc1!(not Ke1?) followed by Rd2 then Rd3 and Kd2 for the win.
I will try and post a possibly complete solution shortly.

Yes. Seems to be a typo also. Because on above position, your EPD shows
Ke1? bxc2= move which can be improved with Kc1!(not Ke1?) followed by Rd2 then Rd3 and Kd2 for the win.
I will try and post a possibly complete solution shortly.
After Kc1, then bxc2 and the king must recapture.

This could be the main line, but your above bxc2 seems to spoil the fun.
Maybe a good attempt for a win is to give up b pawn to give freedom to one of the knights.

Could end up like
this N vs B position which requires half hour search to find the win instead of 0.00.
Will try to play out, and post if something comes up.

I am not sure about it one way or another. I am extending my searches and also looking at alternatives.

Because white's bishop is the wrong color, we can forget about it unless another piece breaks free.

The one problem is that to get the rook around the king, it will have to be exposed to a pawn one way or another.

Then with 55.Re2 (?) I come to the position with Rybkaforum- User's 55...fxe2 instead of ...Ke6 (?)

After 55.Rc2 bxc2 56.Kxc2 after some Forward- Backward I get this output with MateFinder on a weak laptop (no free hardware- time at better desktop at the moment) without tbs:

Thanks for the possible winning line peter. It seems there is an unusual
82...b2 move from black just to avoid the 50-move rule draw. That
82...b2 move gives white better winning chances by capturing the b-
passer for free.

But I think improvement is still possible by playing Ba3 then invasion of K+N against pawns of black.

On this position maybe Na4 then K+N onslaught into black pawns.
65.Na4 could be better than 65.Bb4 on your above line.

Of course there might be improvements of the output- line, which overall is much to much shuffling around, yet I wouldn't say Black's ...b2 is to avoid 50 moves boundary, which to come into horizon would be welcome for Black.

I just wanted to show how MF's eval climbed after some backtracking even on this weak hardware.

Took MateFinder because of its lesser nullmove usage, which is of importance here probably a lot, yet full Syzygys would be good to be used too, which I haven't installed on this laptop, and mate is too far over the horizon.
As soon as I'll find more time and have my main PC repaired, I'll try to make up a decisive and more clear line.

In the meantime I had latest SugaR here too with switched off nullmove UCI-parameter after backtracking to the position reached by

At this node eval falls because of the alternative 57...cxb3 instead of ...ax, not really better for Black but making new Forward- Backward necessary for some 15 moves again.

So that's output after backtracking from 65 to position after 57...bxc3:

Stepping back one more ply now again evals fall because of 57...a3, didn't try this one any more for far, being rather sure it would be the same with losing the clearly winning eval having lost the hash of one ot the other alternatives backtracking to this node, of which (alternatives) of course are some there, all losing in about the same lengthes but not to be seen by the engine with weak hardware all together at short computing time.

That's mainly a matter of enough hash, which the laptop doesn't have, to get a line with winning eval and most reasonable length and moves into output from position at least after 55th move.
