I play for about 15 yrs. I have a 9 ft table in my basement.
I just finished my 2nd hour session with an instructor.
My biggest mistake is i didnt took lessons 15 yrs ago. My mechanichs were not solid.
Specially PSR.
I concur. It took me +20 years to book a session from a very good snooker coach who has an eye for pool also. He was able to correct my mechanics with 3 simple changes in 1 hour and I was kind of lucky it all clicked together. I am still riding this wave almost 10 years, my consistency is really high, despite usually having 2-3 weeks off table due work and family reasons.
I knew all the shots, but I had problems with my consistency. And that was my blocker, I thought I could do it myself, I am analytic, was videoing my playing already for years, but a good instructor knew how to fix issues. And he surely did.
The day after his lesson, I placed 10 reds on a full size snooker table for lineup. I was able to clear the table shooting reds in order with all blacks on my first attempt to make a 107 clearance, my first ever in snooker lineup. My biggest mistake was not to put all 15 reds on the table
