How many issues should you raise on appeal??

Here is some sound advice from Howard Bashman:

When seeking discretionary appellate review in a court of last resort, such as the U.S. Supreme Court or a state's highest court, it's preferable to raise just one or two issues -- and no more than three issues should be raised unless absolutely necessary. Because the odds are squarely against any given case qualifying for discretionary review in a court of last resort, the possibility that a single case might raise three or more separate issues meriting discretionary high court review is highly improbable.
