depends on position
EQUAL?
Maybe. Depends on the positions and the players -- if you're taking the knight/bishop away from someone who is particularly adept with the piece, I would say probably.
mag is right... how the heck would you achieve a position where such an exchange could be orquestrated?
is it ok to trade 1 Queen for 6 pawns and 1 knight/ bishop??
Much depends on when making such trade-off? At the beginning of the game or at the end? At the end of the party such an exchange is quite profitable. Increases the value of pawns. And of course we must look at the position.
