For me, the answer was squaring up my feet more like a snooker stance. It made it easier to get down low on my shot and a bit more awkward to jump up immediately after the stroke. The snooker stance took some time to get use to, but it paid dividends by keeping me from jumping up.
I don't know how I've never seen this hill-hill match. The final rack has the most ridiculous ending I think I've ever seen. Good Lord!
The match is two hours long. Feel free to watch the whole thing or just skip to the last rack. Enjoy.
