nyctc7: Just ram those short putts in (perhaps aiming just slighly right or left depending on the severity of the break) and you will rarely miss from inside 3'!
Aim that slightly right or left but never outside the cup. This is very effective from as much as 6 feet out, as long as you trust that hitting it harder works. It solved my 6 foot problem. Don't think about it, stare at it or get nervous. Step up, aim and hit it. :-)
