The other way to do the 2-Bishop checkmate
The 2-bishop checkmate is one of the hardest checkmates to do with 2 pieces left on the board. I have found how to checkmate with 2 bishops the fastest way. This isn't the way people do tutorials on, and it is simple to master when you've practiced enough. You can premove most of these moves to checkmate.
The goal for the start is to get the bishops together, in a way that is protected. You then want to bring it up with your king.
The aim is to have the bishops connected at all times. To advance, you put one of the bishops in front of the other, in a protected way, to make the cage. If the bishop will be captured advance the king forwards (or to the side if needed) until it is safe.
When the king is pinned to the back-rank, you move your bishop next to your king behind the other bishop. If it is attacked, move your king to protect it. If they go to the same file to where your king is, move your king forwards and then fully complete the maneuver with your bishop, and make it go around. If the opponent doesn't move their king to the same file, wrap the bishop around immediately.
This maneuver will be repeated until your pieces are on the side of the board.
Once you're in that position, don't check, the king can escape the cage and go up the board. Instead, move the second bishop (the one not stopping the king to escape to the next square) A square away to later put the king there. After that immediately put the king there and see where their king is to make sure you don't blunder the stalemate and then check the king with one of the bishops and then checkmate with the other.
If you do it all together, you can checkmate with it.
This method is different from some of the other tutorials, and I believe stockfish actually recommends this version. Now you should practice this with the chess.com endgame thing. It is in Learn-Endgames-Checkmates-2 bishops mate.
