Ok seems like I don't understand and really dislike chess stalemate/draw rules. So if I make a move which is directly causative to my opponent having no moves which would not result in checkmate, this means the same is a draw?? That makes no sense to me.
I think it's because the rules of chess don't state that making a move that puts yourself in checkmate results in a loss, they state that you're straight up not allowed to make that move. So if the only moves you have left would put you in checkmate, they're not legal moves.
