They get no pins for the ball thrown. In other words - if they leave 2 pins standing, and get one of them on the spare shot, they get 8 for the frame if they intentionally foul on the spare shot.
If they intentionally foul on the first shot, it's like any other foul.
Shouldn't be true - I think if it's an intentional foul, it should be zero for the frame. Period.
Bad sportsmanship is bad sportsmanship...
