Piece probability over plies
At every ply, the number of times each piece was played is counted and then divided by the total of pieces moved at that ply. The result is then printed as a probability.
Castling statistics
Simply the percentage of games where white/black played castles.
King side% = (KsW + KsB) / 2
Queen side% = (QsW + QsB) / 2
Castling stats from Lichess games:
W: 81.77%
B: 86.38%
W|B: 95.45%
W&B: 72.70%
King movements
This is the probability for each color that the king moves at least once in the first 10 moves. (around 5% for lichess users)
First move analysis
Probabilities of white's first move as a function of IDs.

Great work, please continue! I can understand your frustration with the forum, it seems that posts regularly vanish due to some mysterious Google policies. Also Github posts just look so much nicer.

Awesome to see it learning the importance of castling by itself :D
The graph is super useful for that.

Sad really that Google Groups don't support editing posts.
It's definitely the best feature of Google Groups. Ideally it also wouldn't allow deletion, and then it would be great.
I'm tired of doing posts on the forum, and I think it's easier for me and everyone if I update them here everytime a new networks goes out. Sad really that Google Groups don't support editing posts.
So you will be deleting old stats?

~You are right that old stats should be available.. I'll see where I can put them. In the meantime I'll just delete them, yeah. I can always recalculate.~

Concerning the "piece probability over plies" - would it be possible to create such statistics from a database of professional games for comparison? Would be quite interesting ...

It's in my plans to add professional games as a reference, yes. :)

Look at that jump in castling in the last generation, awesome to see!! It's already realizing what took humans centuries to realize.

It seems that humans like to castle even less.

Nice work. Seems that LCzero makes too many early rock and queen moves. But why can't I see the humans castling?
pw31
on 22 Mar 2018
I found similar stats about Vassily Ivanchuk in the internet. Seems that he likes to castle more than average lichess player.
mooskagh
on 22 Mar 2018
Sorry I had forgotten to add the castling ! It is in now :-)
Uriopass
on 22 Mar 2018
Looks as if black players (even moves) make more early pawn moves than white players. Is this correct?
Strange that the Ivanchuk data seems to suggest the opposite.
pw31
on 22 Mar 2018
Ah, no, pawn moves are at the top of @mooskagh graph. So, yes, seems that black players make more pawns moves than white players in the opening.

Would it also be possible to produce graphs like in http://lczero.org/stats? Maybe the reason for a draw is difficult though.

I'm planning on making a gif of thoses, from gen1 to gen15.
EDIT : Done !

Another pattern seems to be that black players prefer knight moves between about move 10-30. Maybe they need to trade their bishops more often against white knights ... interesting.
pw31
on 22 Mar 2018
Added gen16, castling going up ! Openings are becoming less homogenous.
Something that I noted also, is that in lichess games black castles more often.
It could mean that black's castling percentage will become superior to white's percentage, as it's currently inferior. And that will be amazing.
Uriopass
on 23 Mar 2018
The GIF is a nice addition. A suggestion is to normalize and fix the y axis, so that it shows a more consistent picture of the development of the generations.

Is this based on training games? Or evaluation matches?

Interesting to see how similar the Id77 and Lichess piece-move-probabilities have become. It's all there, casteling between mv 10 and 30, the odd-even (i.e. black-white) saw-tooth like patterns of pawn and knight moves, fascinating. It seems like the humans make more rock moves (and less bishop moves) around moves 40-50, but that's about all I can see concerning the differences.

Here is analysis how well Leela is able to follow alpha zero's and Stockfish's moves in the 10 published games from Deemind. Maybe it offers some diagnostic value. At least it convinced me that Leela was learning something during the self-play elo regression period.
EDIT:
It was requested to test how higher playouts effect.
Got following results for 800 vs 100000 playouts for Net ID 81:
A0 38.7% -> 42.5%
SF 35.5% -> 41.6%
UPDATE:
Previous graph was calculated partly with wrong lczero version that caused IDs 55-80 be completely rubbish and 80+ ones be slightly inaccurate. The graph is now recalculated with correct engines for each network. Also simplified the graph as it was getting hard to read.

Thanks for posting this ! If you could keep it updated that'd be great ! I'm sure lots of people (including me) are very interested to see how it'll change over time :)

Interesting how the 2 graphs have started diverging and Leela is following the A0 path closer than the SF path :)

The First move analysis is amazing
can you do also one for black? Given than e4 is played, since its the most played move by white.

Updated main graphs (king movements etc) with data from _all_ networks, it took some time to aggregate everything so I put it online, see here.
Using this I want to try to make the same types of stats as in the AZ paper about openings..
