Yet another game analysis method

[Ferdy]

This method involves 2 analyzing engines, Lc0 and Sf10. In the opening and early middle phases Lc0 will take charge on the analysis. The rest will be done by Sf.

Code: Select all

Q=9, R=5, B=N=3, P=1
piece_value = 9*(wq+bq) + 5*(wr+br) + 3*(wb+wn+bb+bn)
pawn_value = wp+bp
if piece_value >= 50 and pawn_value >= 12 then use Lc0 othewise Sf.

Analysis features:
1. Light descriptive comments, i.e "better is" etc.
2. Variations are generated by actual game playout up to 5 plies.
3. 2 analysis engines

Pick one of the best games of Kramnik (retiring from chess).

Impressive Lc0's opening analysis even on this slow backend.

Another game is a bit tactical. A human vs machine.

Impressive Lc0's opening analysis even on this slow backend.

Another game is a bit tactical. A human vs machine.

Hi Ferdy!

Is this built an extension of the Nucleus analysis tool or Chess Artist ?

Hi Ferdy!

Is this built an extension of the Nucleus analysis tool or Chess Artist ?

I already have sf and lco combo where sf will handle the ending. It is not in Nucleus and not in Aiquiri either, not released. For chess artist, I might include this feature.

Might be the perfect opportunity to upgrade to python3 and the latest version of python-chess, letting it deal with the uci communication (chess-artist doesn’t know what to make of lc0 at the moment).

But no checkin for Linux users?

[Dann Corbit]

This kind of thing is really useful to people who want to learn and improve.
An engine that is 5% stronger, but nobody understands the moves? No revolution there.
Something that explains the good and bad moves?
Genius in action.

And all the things you make are useful. I praise you sincerely for your efforts.
