So I've been playing for a while now and not a great golfer (off 20) but love the sport. My problem is that one day I can hit my irons terrifically, long and dead straight. BUT on every other day, i have a problem where i cant actually get the ball off the ground. I hit them fat a lot of the time and if I'm not doing that, i shank/grubber them hard left.
Is it a mental issue? How can there be such a variance from day to day?
