One thing I use before i play to give me confidence in my putting, is to start off at a real close distance, about 10cm, putt at this distance till i feel confident and just cant miss, then gradually move the ball back further, about 5cms each time, till im about 3 mtrs back at the most. This gives me alot of confidence as I am holeing the putts consitantly, make sure its a straight putt. To put some pressure on yourself like comp conditions, when you feel you want too move back say too yourself, make this and you can move further away, miss, and you have too move closer. This will usually take me about 10 - 15 mins.
What do other people do before rounds?
