Saw this on BBE, so I thought I'd post it here:
Suppose that you're bowling in league, and you've got the front 11, but you've already shot 300 during the current season. You get eight or nine on the fill and you get a 298 or 299 ring, but if you strike, you get nothing. Let's also assume that the extra pin or two doesn't make a difference in terms of the results of the team game or series, and that you don't need the strike for 800 or anything like that.
What do you do? Go for the strike, or try to leave something?
