'Stalemate=win chess has little effect on the opening and middlegame play, mostly affecting the evaluation of certain endgames. As such, it does not increase decisiveness of the
game by much, as it seems to almost always be possible to defend without relying on stalemate as a drawing resource. Therefore, this chess variant is not likely to be useful for sidestepping known theory or for making the game substantially more decisive at the high level. The overall effect of the change seems to be minor. '

stalemate should not be a draw
Sort:
When your opponent has no pieces other than the King which can move and the move which you're planning to make doesn't deliver check, take a few seconds to check that they will have at least one legal move. It's actually very easy to do but requires a little discipline. You're going to need to train much greater discipline to progress in Chess so learning to avoid stalemate is a good way to start.
