Once you took a foul, you were under the gun….second scratch, your opponent gets ball in hand.
….saw an interesting situation in Detroit….late 70s…there was a tricky corner pocket on table 4 at the Rack….ball would spit out often…
…it had been shimmed with rubber from a truck tire….set is hill/hill for 5 Gs…the 8-ball is froze on the long rail, one diamond from the corner.
….cue ball is almost straight in six inches off the far end rail…9-ball is froze middle of the rail near the cue ball.
….so the guy pushes by just tapping the cue ball.
So now the other guy has to make a decision…if he shoots and it spits out, he’s going to eat his heart out…if he says shoot again and the guy fires it in and gets on the 9-ball, he’s also going to eat his heart out…so he taps whitey back…lets the other guy makes the decision for him…
…..his mind will be clear.
