Thank you all guys, if I understand right here are no practice fields like a driving range, out of bunkers or putting greens. Have to practice by playing, which hopefully does'nt mess up my scoring average. Still wondering, how I can miss putts from 0,8 ft. but will practice.
When I was playing real golf, I did'nt like putting too, but it was never this bad. So long I will only compete in games where I do not need to putt.
Thanking you again, you're great.
