I checked the Game Analysis and this is what it says for why it was a draw:
I was not aware of this rule... fair enough I suppose... Although if this was a game between friends with a real chess board I think we would have considered it a checkmate.
Can someone explain why the app decided to automatically call this game a Draw at this point?
In this screenshot of the last move, I am White and I am working to corner the opponent's King. Right before this I converted a Pawn into a Queen, and then moved my Castle to h5 to keep his King from moving further down the board.
The way I see it, that move should have been a Checkmate! Any optional move by Black's King would result in it's capture.
