With the advance of the technology and the improvement of the chess engines, more and more chess players have started to focus a lot on the opening and slightly disregard the other phases of the game, especially the endgame. While knowing your theory well is very important, you should find the right balance in your preparation as to include everything, from strategy to tactics to learning how to manage the theoretical endgames. One particular endgame that has been seen a lot in practice and has proved to be quite tricky even for the top players is the rook and bishop versus rook.
