If you are talking about pitching and chipping... if you typically use your 60 degree (or highest lofted wedge) around the greens at your home club where the greens are faster and firmer, then you might try using a lower lofted wedge when you encounter slower / softer greens. The ball will roll out more with the same amount of effort.

It’s always tough dealing with different greens. If playing a new or different course, I try to spend most of my warm up time on long, lag putts. Also remember that the slower the green, the less break to play. Good luck out there.

May sound weird. Have putter for slow and fast greens. Most away courses are slower. we have second fastest greens in area.

I find that I tend to putt better on any new course by trying to get a gauge of how the greens roll out. By this I mean, how the ball reacts to "taking the slope" and what its going to do after I hit it to where I want it. Typically I'll hit some puts from 5 ft and really watch how they roll AFTER the cup to gauge my speed. Then I make an imaginary hole that I putt to and let the ball do its thing. Try at different lengths and it should get your speed adjusted. Trust your judgement and don't try to force the ball to do anything, but give it your best stroke every time.

Always rock up a bit earlier, once you've warmed up with your irons, spend 15 minutes on the practice green and try to get a feeling for the greens in advance. You'll generally get a good idea of the speed of the greens from there (although a lot of clubs tend to neglect the practice green a little so it's not always ideal!). Warm up with longer lag putts so you get a feel for roll out and then work your way in. Good luck and go well!

I think that's one of the most difficult things to adjust to; varying green speeds and firmness. The other thing to watch out for is inadvertently changing your putting stroke to match playing conditions. In addition to lag putting,I'd try and find a 5-6 foot putt on the practice green, and see how much difference there is between what you eye sees and how much the putt actually breaks.

Good Luck.
