who is EK?Nick Burrows wrote: ↑Thu May 20, 2021 8:59 pmHe 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 does beg the question that if the numerical valuation of pieces is so easily drawn into question, why we persist with it. I did overhear Howell mention in the commentary the other day that Alphazero does not adhere to that system.

Re: Piece values
We persist with it because it's a decent first-level approximation that can help us get to the level where we start realizing its shortcomings.

No one pretends it's anything other than a rough guide.

Re: Piece values
Well yes and no, computers use it and have a numerical value system in place, well except Alphazero according to James Howell.

Computers take also into account their activity, so they do nuance it quite a bit.MJMcCready wrote: ↑Mon May 31, 2021 4:32 pmWell yes and no, computers use it and have a numerical value system in place, well except Alphazero according to James Howell.
