Do anyone think that a bishop and a knight is worth a rook at the begining of a game.
Bishop + Knight > Rook (at the beginning of the game)
Bishop + Knight > Rook (endgame)
Bishop + Knight >= Rook + Pawn (greater than or equal to, when the rook has a pawn)
Bishop + Knight < Rook + 2 Pawns
well for me yes!
Ajfonty said it right
Of course it depends on the specific position -- but I'd usually rather have the bishop+knight.
Bishop+knight, I reckon, need not be sacrificed for a Rook. But, at times, it pays to sacrifice Bishop+Knight for a Rook+Pawn.
