What's the best alternative to the 'scoresheet' blunder checking strategy? In Simon Webb's brilliant book, Chess for Tigers, he advises that a player write their move on their scoresheet before playing it. Then, right before you play your move, you check it one more time to ensure you haven't made a blunder. I used this strategy with great effect in my games, and it cut down my blunder rate considerably.

Unfortunately, Fide changed the rules, and now this kind of strategy is illegal: you have to write your move down after you play it. Is there a substitute for this strategy that still uses the scoresheet, but is legal under Fide rules?
I don't know of any proven method but here's one idea: you could try to imagine writing the move. Translate your move into algebraic notation, imagine the text on your scoresheet, maybe even trace it with your finger. Hopefully that will be enough of a pause in your train of thought to enable you to see the move from a different perspective, which I think is the rationale behind the "write before you move" approach.
