2 Bishops vs 1 Rook
considering how bad did both played, draw is a fair result.
opening - black creating weakness after weakness, doubled isolated pawns; moving king 5 of first 17 moves right into the middle of chessboard.
middlegame - why is white opening his kingside ? to clear files for black rooks ?
endgame - on moves 39-41 white can capture black rook.
sorry guys, I am not really good chessplayer, but as I see, chess is not really an easy game.
On move 63, you ought to have played b7 instead of c7. So ignoring mistake up until this endgame...c7 forces the rook to take because the king cannot move anywhere. Should be an easy win from here.
EDIT: Oops, I thought you were white. This endgame is lost for black. You were lucky for a draw. I would recommend that you work on other aspects of your game before you try to analyse this specific endgame position.
