can some on help me with value

Queen = 9 Rook = 5 Bishop =3.25 knights = 3 Pawn = 1 King = infinite

I thought that the knight and the bishop both have equal value (=3)

You're correct.

Here is Garry Kasparov, explaining why the bishop is valued higher.

Don't get too hung up with the point values of the pieces. At the start of the game, when all pieces are on their home squares the values are pretty much as given in post #2, although many say the Bishop and Knight are both worth 3.

However, the pieces don't stay where they started, do they? Pieces can improve their value or have it impaired by relative position. Just because you, or your opponent, may have more "valuable" pieces on the chessboard doesn’t mean much if their positions are poor. What is the value of a Rook locked behind a pawn on their starting squares compared to a Rook on an open file, or pinning a King?

If you are considering an exchange, be sure to consider the relative benefits both you and your opponent will gain. That is why sacrificing a Queen to win a game becomes important. A Queen is worth 9 points, but winning the game is much more important.

So, although the points can be helpful in assessing the relative strength of each piece, you need to evaluate the game situation. Sometimes the pieces are worth much more (or less) than their starting values. What is a pawn worth just before promotion?

The game is over when the King is checkmated (he cannot be captured), so his value is "infinite". The King can only move one square in any direction (slightly better than a pawn), so at the beginning of the game, in the centre, he is weak and needs to be defended. But as the opposing forces are depleted, the King gains more "strength" and can venture into the battle. With only a few pieces on the board, the King can be instrumental in checkmating the opponent!

Everything is relative . . .  Good luck!

It depends on the position. If you are in an open position and  have the Bishop pair and no Knights and your opponent have only a Bishop and a Knight the Bishop are valued higher. In a closed position the Knights used to be valued higher. But in general you can say they are equal in value.

You forgot to answer the question in the topic of this thread you spam in.

Piece value is mostly debunked, although I think a lot of chess players might use it in the narrow confines of trading unbalanced pieces, and even then, mostly if they feel they're in an even game and  are trying to unbalance the game.

For example trading rook for a knight and 2 pawns. But piece value is the last thing considered. they'd be more interested in things like how active is your opponent's rooks. If your trading a rook for 2 pawns and a knight or bishop, and your opponent has a rook stuck in the corner and needing several moves to activate, the most chess players might think trading a rook (5 points) for a [ knight (3 points) + 2 pawns (2 points) ], is worth doing, in the expectation that the game will end before the opponent has a chance to activate his lame rook.

The knight and bishop are both rated 3, theyre only different value for the top top players, difference in lower levels are negligible
