which is the best piece in chess?


totally agree

The question is no real question, since everyone can figure out the following truths:
_ While the King is the most important piece, the Queen is the most powerfull.
_ It happens the Knight gets more important/powerfull than usually, due to tactical patterns related to its unique abilities. A well placed Knight, protected by a pawn, can prove more powerfull than a Rook, for the rest of the game.
_ The combo Queen+Knight proves overly dangerous and painfull to counter.
_ Ultimately, in some given positions or situations, a weaker piece, even a pawn, can become the center of the attention, when the outcome of the game depends on it. Any piece able to deliver a one move checkmate is the star of the moment.
etc.
