Question
What is the general idea of winning a king and rook and bishop vs king and rook endgame?

Answer
Hi Hannibal,

This is a very complicated ending for both sides, one which even masters can have trouble with.

Much depends on the position of the pieces when this endgame is reached. Generally speaking, from an equal position (no forced loss involved), it should be a draw but often in practical play - it isn't.  

The winning try for the stronger side with the Bishop, involves forcing the opponent's King to the back rank.  The weaker material side has to avoid this at all costs:

I would suggest getting a copy of the classic endgame book: Basic Chess Endings by Reuben Fine:

Also, take a look at an endgame tablebase:
