Okay. I am using SF Dev to analyse now. Lets see what happens.

Was SF dev the engine you used for the analysis above?

Was SF dev the engine you used for the analysis above?

The dev doesnot find variations in appropriate time. I used mostly Allie 0.5 and Honey FD

What typical times and depths did Allie & Honey go to? (I don't know what the "FD" means.)

Others have already used SF-dev, so it's probably good that we now have engine variety.

AFAIK For NNs depth does not matter much. For them the search is key. In key positions they play it intsantly where sf needs a depth more than 45 to confirm it. I feel like they play of intuition. I used allie for getting the lines. Then used Honey FD. FD means fortress detection as I felt there can b chance of a fortress and there is in the Ng5 line. Dev is fine for play. Analysis work is better with other forks.

After a deep evaluation, 3.3 billion nodes, LC0's Qf6+ score falls a little. It doesn't see a clear win. It used 185 GB of RAM by this point.

185GB RAM! How much RAM do you have?

185GB RAM! How much RAM do you have?

512 GB. I'm working on an NLP project that needs this much RAM. And thanks for posting this LC0 analysis in the proper thread. I think I had some old cookies or something.

[jp]

512 GB.

That's great. I wonder if it'll work (for others who don't have so much RAM but are patient) using virtual memory.

A much discussed position:
1r3r2/4bpkp/1qb1p1p1/3pP1P1/p1pP1Q2/PpP2N1R/1Pn1B2P/3RB2K w - - bm Qf6

The biggest failure with this position was Fat Fritz (tested by Peter in mid-October). Maybe someone with a copy can try again with long time and see whether Fat Fritz can pass this time.
