Shmidt musta really wanted to keep you on the hook if he just won often and not every single time
At my best 20yrs ago, I managed to steal a short set off a pro a few times when tables broke easy and runouts were there to be had. Never did I imagine I could hold up with them. I was an impossibly huge dog in any tactical rack and not a single onlooker would think I could hold my own with those guys, even if I did manage to get a lucky short race win.
I too took 12 years off after a back injury and other passions putting a halt to my pool playing days. You are def right that it is not like riding a bicycle and tbh I never really expect to be the player I was given I used to play every day the amount I now play in a week (and much much less seriously at that). I couldn't see things at the table as I did and I frequently just misaimed shots or failed to adjust for sidespin correctly as I once did effortlessly subconsciously, let alone be able to execute what I did manage to see right with anywhere near the regularity. That said, seeing connected balls and finding efficient runout patterns using solid positional fundamentals never left me. That stuff made it into what psychologists refer to as 'procedural memory'....basically stuff you've done competently so many times that you never forget it. I had to relearn how to shoot and how to see shots at the table and when down, but I could diagram out runouts as well when I got back as before I stopped playing...that never leaves you.
Long story short: No, you never could hold up with John Shmidt
Cool story tho.
