Double Bishop Endings
Double bishop endings are chess endgames where both players still have the two bishops. So there are four bishops zinging around the board. This is a very complicated endgame, far more complicated than single bishop endings.
These double bishop endings often transition to a single bishop ending, through the exchange of one pair of bishops. Obviously it is a critical issue whether it transitions to a Same Color Bishop Ending (which are often easy to win if ahead material) versus an Opposite Color Bishop Endings (which can be drawish, but not always). The tendency is for bishops on the same color squares to exchange, leaving a Same Color Bishop Ending, but the other type can also occur. And obviously it can also transition to a King-and-Pawn Ending through the double exchange of all 4 bishops.
