I always thought it was mobility.

We need an "upvote" feature for posts like this. Good oneJohn McKenna wrote: ↑Thu Jun 27, 2019 7:18 pmWe all know that the interrogation will produce the following answer -
8 (pawns) + 6 (2 knights) + 7 (2 bishops) + 10 (2 rooks) + 9 (queen) + 2 (king) = 42!
Lose one queen and it is a disaster, Lose 1000 queens and it is just a statistic.

Thanks, Joey.
However, others would then want a 'thumbs down' button.
Best if we leave thumbs twiddling...
And I always thought it was a lack of nobility.

I always thought there was something fundamentally wrong with the Game.

Re: Piece values
In "Applying logic in Chess" by IM Erik Kislik, he has a chapter on piece values. He says that after years of testing by Stockfish and Komodo et al, the settled upon values used by the engines is:
Pawn = 1
Knight = 3.45
Bishop = 3.55
Rook = 5.25
Queen = 10
Bishop Pair = +0.5
Safe King in Endgame = 4
Early in game Rooks have less value and increase as game progresses. A single rook is worth more than 5.25.

Re: Piece values
My formula is number of reachable squares equals piece value points. A checking piece is infinity/2 and a mating piece is infinity/1
I float like a pawn island and sting like an ignored knight

Re: Piece values
Once you go ELO2000 and up you'll see the numerical values are relative to the stage of the game as rooks are usually the worst pieces on the board in the opening, and not that much use in the middle game usually, but in the endgame then their true value can be seen. On move one the only things that have any value at all are pawns and knights because only they can move.soheil_hooshdaran wrote: ↑Wed Apr 18, 2018 12:08 pmHi.
What's the basis for assigning numerical values 1-3-5-9 to pieces?

Re: Piece values
Everyone knows that the Knight is better than the Bishop.

Re: Piece values
Not in endgames where there are pawns on both sides of the board, then a knight is usually worse.

Does EK discuss the changing value of a pawn as it progresses from the 2nd to the 7th rank?Nick Burrows wrote: ↑Wed Jun 24, 2020 8:20 amIn "Applying logic in Chess" by IM Erik Kislik, he has a chapter on piece values.

Re: Piece values
I don't think we will ever see that happen which draws into question the whole numerical value system. Even if we factor in time controls its tricky. What about blitz games where succumbing to knight forks is harder to avoid.

Re: Piece values
He has a paragraph saying in certain positions a pawn on the seventh rank is worth at least 3 pawns, but trying to work out when its worth 2 pawns etc is not worthwhile.John Upham wrote: ↑Wed May 19, 2021 11:56 amDoes EK discuss the changing value of a pawn as it progresses from the 2nd to the 7th rank?
A fast/dangerous/well supported passed pawn is likely more valuable than an extra pawn for the other side

Re: Piece values
It's all relative, we could be here all day. Trying to evaluate the numerical value of a good knight over a bad bishop in an endgame is also nigh on impossible.
