I've noticed that some players who, for one reason or another, have a current rating far below what could be called their 'true' rating, are able to enter banded tournaments for which they are vastly overqualified. how about if, once you have entered such a tournament and your rating exceeds the band maximum, you are automatically kicked out (as long as the tournament hasn't actually started)? seems to me it would be fairer. not perfect, but fairer...
