From the main menu select practise, and then chipping practise.
That’s the easy bit! You now have to get 25 shots within 5ft, but the game doesn’t tell you when you get one close.
The good news is that the achievement will pop mid session, so just keep going until it unlocks.
The lies and shots are tricky, so make sure to check your distance and the shot percentage before you hit it. Also the shots repeat, so try and remember what you did and repeat it.
It took me about an hour!!
Good luck!!
