It’s delicate, but you can hook them on the point potentially. I tried it with the OB frozen with about a quarter ball overlapping the side pocket opening. Give yourself maybe 10 degrees of angle with the cueball on the opposite side of the pocket and hit a very soft shot approximately full ball. You need the cueball to barely get the rail but if you do you get a corner hook. Try it at home and see if I’m crazy or set it up wrong.
it's damn sensitive but i like it. here's alex higgins playing it on a snooker table:
