<In the struggle between a rook and two minor pieces, there is generally equality if the side with the rook has 1 or 2 pawns more. Somewhat fewer pawns are required if both minor pieces are knights, and on the other hand 2 pawns are necessary if we are talking about the bishop pair.

The average value of the exchange (rook against a knight or a single bishop) is about 13/8 of a pawn. The advantage for the side with the rook is only 1 and 3/20 of a pawn if the opposing side has the bishop pair. If all the other minor pieces are still on the board, the value of the exchange drops by ¼ of a pawn. If, on the other hand, the queens and a pair of rooks have been exchanged off, it goes up by somewhat more than ¼ of a pawn. >
