"(including, of course, why the chess king is to be valued at 2 notional pawns!)"

I always thought it was mobility.

We 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!
We need an "upvote" feature for posts like this. Good one
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...

I always thought it was mobility.

And I always thought it was a lack of nobility.

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

There's nothing about a flawed masterpiece that can't be attributed to its creator(s).

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.

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 :mrgreen:
