What is the difference between a force out and fielder's choice?

Answer 1

It's a judgment call. I think the answer is this: A play is scored as a fielder's choice if, in the official scorer's judgment, the fielder had a clear opportunity to throw the batter/runner out at first, but instead chose to putout another baserunner. So I suppose a batted ball is scored as a force out if the fielder has no realistic chance (in the scorer's eyes) to get the batter/runner out at first and his only choice is to tag another runner or throw to another base.
