How that is a draw? And why I scored -1
It's stalemate, the King has no legal moves to make. According to the game report you missed multiple wins which is difficult to see considering the material advantage you had.
Hi,
you lost a rating point because the game ended in a draw and your rating was higher than your opponent. The reason it was a draw is because you stalemated instead of checkmated your opponent. Stalemate is when you prevent your opponent from making any legal move without attacking their king, preventing them from continuing the game without correctly ending it with an attack on their king. A king can never move to a square that is under attack by an opponent, which in that game you attacked all squares around the king except the king. One way to minimize that from happening is to always attack the king directly each move so that in such cases it would be checkmate instead of stalemate. However an even better approach is to be more aware of where the king can move next turn after you make a move prior to making that move. Hope that explains the situation and next time make it a checkmate and win!

The problem is that when your opponent is down to a lone king stalemates always look attractive. That's because you're trying to limit your opponent's king's mobility and stalemate is the ultimate limitation.
The answer in those situations is to consciously check before you make any move that isn't checkmate that the opponent's king has breathing room - until it stops being conscious.
Continually checking the king doesn't often work though. Perpetual check is also a draw.
If you have, for example, king and queen, king and rook, king and two bishops or king bishop and knight against a lone king then checking all the time usually just means you don't get to checkmate. You can never force a lone king off a square by checking because he was going anyway. You should rather attack the squares where you don't want him to go.
If he has other pieces that can move, then immobilising the king is fine. E.g. the first move in this alternative from move 44 leaves Black's king without any moves, but that's OK because he still has pawns that can move.
But you're not alone. Here's a 2500+ grandmaster doing the same thing.
A good example of avoiding stalemate is the daily puzzle from yesterday, after a few moves white played e4 but did not capture the easy pawn on f5 as it advanced, it was a free piece but by capturing it the game would have been a draw. If you do the puzzles regularly you will come across one that has two sacrifices as the player is playing for stalemate, some players are sneaky and will play for the draw.
