Creating meaningful PST's from PGN
A new tool is available that creates the 12 Piece Square Tables (PST) for the MiddleGame from a PGN database. The tables can be used for 1) move ordering, 2) pruning decisions, 3) reduction decisions.
Example-1 : PST made from a 82.000 human game collection between players with a minimum elo rating of 2600.
Example-2 : PST made from a 66.000 comp-comp PGN between engines with a minimum elo rating of 3300.

Idea #13 [experiment]
90% of coding is debugging, the other 10% is writing bugs.

Re: Idea #13 [experiment]
How does this work?
The PST's in your examples look totally different than the results that I get when I tune the PST's with logistic regression.
I don't use games from CCRL, this could be an explanation, and I tune a lot of other parameters with respect to pieces too, but I would expect the trend to be comparable.

Re: Idea #13 [experiment]
There is no tuning, just a raw statistic from a large quality PGN, not suited for evaluation.
Code: for each move : pst[piece_type][square_from]--; pst[piece_type][square_to]++;
That's basically all there is except handling a few side effects.

Re: Idea #13 [experiment]
Thanks, It looks useful, especially for move ordering. I wouldn't however call them PST since it makes confusion. I would rather call them piece-square-difference (PSD) or something like that...

Re: Idea #13 [experiment]
How is this possible then?
A white pawn on d2, for example, can never get positive hits, no?
And afaik, a pawn can never go back ...

Re: Idea #13 [experiment]
All pieces (not only pawns) on their original square from the start position end up in a large negative number and need correction.Joerg Oster wrote: ↑Sat Aug 08, 2020 11:59 amHow is this possible then?

Is this a hint that the method can be improved?
Currently a pawn move d2-d3 or e2-e3 is penalized, while f2-f3 not.
How would the numbers change if you only count the to squares?
How would the numbers change if you take into account the game result?
This would probably result in some kind of "tuned" values.
Question is, how to count then ... +1 0 -1, or +2 +1 -2 ?

Yep, the calculation of the root pawns needs improvement.Joerg Oster wrote: ↑Sat Aug 08, 2020 1:00 pmI see, thanks.Rebel wrote: ↑Sat Aug 08, 2020 12:22 pmAll pieces (not only pawns) on their original square from the start position end up in a large negative number and need correction.Joerg Oster wrote: ↑Sat Aug 08, 2020 11:59 amHow is this possible then?

This is already taken care of, only moves from won games are counted.Joerg Oster wrote: ↑Sat Aug 08, 2020 1:00 pm How would the numbers change if you take into account the game result?

Things are better now, maybe (in the end) it can be used for evaluation as well.

1) make the bonuses relative. What I mean is for each position reduce all the (piece, tosq) combinations that could have been played by one and add the negated negative sum to the (piece, tosq) that was made. This will make a pawn moving to last rank a huge bonus while it gives an extremely small bonus in your current scheme since most pawns won’t reach rank six or seven.
2) make each game count as much. What I mean is that a half as long game’s positions should count double as much so each game give the same amount of bonuses.
3) make two tables for each piece type, one for early stage and one for late stage and the bonuses should be distributed to the two tables depending on how much the position belongs to either stage. This will make a Hugh gain in the endgame for the king and will also change the other pieces quite a lot. The only problem is that not everyone counts gamephase the same.
Good luck!
