What are the rules? Here are some questions??

1) If the best ball might be ok.. and a provisional is required, do both players hit a provisional?

2) Do you do best ball on the putts as well?? Second guy would get an amazing look at the putt.. that doesn't seem right

3) Do you have to duplicate your playing partners lie?

My friend andI played best ball but didn't know all the rules. I'm pretty sure we followed all of them as nothing strange happened where we didn't know what to do. We shot a 4-over 76 at glenmar Is that a good score for a 19 and 20 handicappers?
