Do you want a hypothetical answer?
Hypothetical/silly question... Do you think the King is worth 3 points?
Maybe if it was a piece it would be worth 2 or 3 points but that doesn't change fact it is the king, since it cannot be taken I guess it is both priceless and pointless!

By my reckoning the king is worth at least 40 points. What would you rather have, all your other pieces or your king?
If there was no such thing as check then you could roughly score pieces based upon the number of squares they control. So a king would be 3x a pawn, 9/13 of a knight, 3/5 of a rook etc. So somewhere between 2 and 3.


In the endgame, where there is usually little danger of checkmate, the fighting value of the king is about four points. In the endgame, a king is more powerful than a minor piece but less powerful than a rook.

Not silly at all. As the endgame approaches the king needs to get more involved, in fact it's one of the most important pieces. It's worth about 3.5 to 3.75 on average. Clearly it's value changes like all pieces, it depends on many factors, but that's an average. Use it.
It seems as far as movement ability goes, the King would be equal with a Bishop or a Knight (ok I know Bishops are worth slightly more than Knights), but if you consider how the King moves, one square to any color in any direction... Is this at least just as good as the Bishop, who can move across the whole board quickly, but only stay on one color the whole game?
