your play is incorrect, then you score -2 points.
If you do not declare that you are confident,
then you score 1 point for a correct play and
0 points for an incorrect play (or no play at all).

plays should be +1/-1 similar to +2/-2

This is a simpler scheme, and might be more practical
because there are already clear precedents with many
academic multiple-choice exams having negative grading.
I think Tim's idea was to enable a solver to say "I think
X is the play but I'm not confident."
The 1/0/-1 system doesn't really cater to that.
But I think the 1/0/-1 system is a better suggestion.
It decreases the luck in the test because it discourages
wild guessing.

Rather than right or wrong, the /size/ of the
error is what is most interesting (to me at least).
