Engine endgame position

Post by Look »

I was watching some previous engine games, and I came to this position:

[d]8/6p1/1b5p/1P1k1P2/5P2/2R4P/r2NK3/8 b - - 0 46

Black played ... Rb2 and went on to lose. Can ... h5 save the game ?
Farewell.

Guess yes, but Black can still fail easily, as one of three games I did let play out shows. After some Forward- Backward with SF dev., 30 threads of 16x3.5GHz and 32 G hash after 46...h5:

Yet Lc0 lost with Black in game of reversed colours, 47...Ba5? instead of ...Ra7 might have been already crucial, regards

This position seems like a shallow river. Without knowing deepness at parts, I would be drowned crossing it.

Position after 46...h5 47.Rg3 can be taken as single best move test position with 47...Ra7! only holding the draw for Black, in that way it could be called a game changer too.
After some Forward- Backward from and to it (already played 47...Ra7!):

At position with Black to move at 47th, Lc0 with 3070ti and net 6147500 takes some time to keep Ra7 up stable in output, Torch failed to do so even after some Forward- Backward at my trials with online- installation of yesterday's and a few minutes (depth 45) with option 40Mb of free account (not being allowed to store output). After going into the lines after ...Ba5 and Ra7, time to depth after returning to root position gets longer, but up to depth 39 (again some minutes of pondering) engine yet sticks with wrong move (47...Ba5?) still, regards

I noticed that most of the other engines liked a similar line at some point in the calculation.
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.

46..h5 47.Rd3+? (instead of the much better Rg3) gives away White's advantage too easily. After some Forward Backward from and to it (after your Huntsman- output 47.Rd3+? played):

Position aftger 47.Rg3 isn't very difficult to be solved with enough hardware- time, but to see a clear winning eval with second best move 47...Ba5? (am) and a clearly drawing one for 47...Ra7+! isnt' as trivial as simply keeping the correct bm in output.
Again SF dev. after Forward- Backward and 47....Ra7+!:

Weiß hat minimalen Vorteil.

And for some engines I tried, even this is sometimes a matter of waiting long enough for a second time ...Ba5? yet to return again for some more ponder- time, especially with multipv=2, this time (with still from Forward- Backward full hash) at most discriminating test position before 47...:

Time to solution changes here from run to run and from compile to compile of course, even not so much as for my few trials with the compile above and with v0.32.0-dag+git.4cfe7426. Net was always 6147500.

And as told in posting above too, Torch wasn't to be got to favour 47.Ra7 at all, not even with some Forward- Backward at my trials way back then (not with empty hash started to depth 45 and not after Forward- Backward of both relevant lines till dept 39), but of course I know the installation to be used in browser ("Torch 40Mb download") isn't the strongest one.
