As a general rule, the queen can _always_ force a draw, because of the many checks it can give. And it often finds ways to pick up a pawn here and there. The exceptions occur when the rooks get doubled and can't be separated, but even then it is not a bad idea. I simply count a queen as equal to two rooks, period... And in 99.9% of the cases, that is at least correct... and often the queen is better when there is another piece on the board to help...
