These pay now/pay later problems rely heavily not only on the amount of immediate shots left but also on the relative timing. They can be, like this one is, very touchy. In the variant all I did was move the opponent's spare from his 2pt to his 6pt and already it's correct to pay now. The further back you move that spare the more correct it will be to pay now.
