This story takes place at the Times National Su Doku Championships, while I was solving the puzzle. As some may know, my preference when doing sudoku is to not use pencilmarks at all, because I find it more satisfying and the solution looks nicer. But this was competition, and no time for such subjective concerns, so I'd pencilled candidates into some cells. Anyhow, Eventually, through some tortured path of logic, I found a cell that couldn't be a 9 (or maybe it was a 2, I don't remember. Anyway...) and scanning along the row, I found that only left one place for the 9. Placing that opened up the puzzle rather, so there were a lot of new moves. Normally I'd fully work out the moves, but this was speed solving, so I just started entirely using my candidates (a very rare thing for me; on the odd occasions I write in candidates, I generally use them to get over the main hurdle, then pretty much ignore them). Now once you have candidates in, doing this bit of the puzzle is very fast. But you're relying on your candidate lists being correct. If just one little number is wrong, the whole thing'll fall apart. So a kind of panic sets in, me hoping against hope I'd got my lists right (I had as it happens), but not able to check because I'm writing in numbers so fast. Has anyone else experienced Blind Candidate Trust Panic?
