I have a large group of buddies that usually all play at the same time, so we often play 2-3-4 man scrambles. It took me a while until I realized I wasn't seeing much improvement because I'm normally longer than nearly all of my playing partners and would normally hit last, this would cause me to "go for it", The end results were that my personal game just could not improve because I was never looking to make the "smart" play. When instead of scrambling we would play heads up and keep individual scores I started realizing I had nearly zero "course management" skills and my score would suffer mightily for it.
I came to a decision to start playing the higher percentage shots that I knew I had a higher probability of pulling off and nearly immediately my scores starting improving at a very please rate. I know that I am not very smart, but I have figured out - (at least for myself) - ""TRYING TO BE A HERO WON'T GET YOU CLOSER TO ZERO""!!!
God Bless!!! Ray
