I'll give it my best--as far as books to read--I don't know any I would recommend to learn capping golf. I think it would serve you better to go back past years archives here on events as they come up and see what angles others are using and make notes on them.This has been a pretty successful crew and many make explainations on their selections.
I think you are making wise decision on selecting golf to wager on as there are a lot less varibles than team sports and with stats available on Stans site it will save you lots of time in research. It has cut my time by 75% from old days. There are several to coat tail here as you go along and pick up some cheese--but do not get to confident and bet modestly thru learning process as it is always easy to get on someone after hot streak and everyone has cold streak. One area to coatail would be Stans selection on Senior tour in particular.He has very few down weeks in past 5 years.
If you decide after a year or so this is your cup of tea I might suggest you go a step further.Everyone has same stats available and if you crunch #'s most will get same result,however there are 3 things in golf for most part that will make deviations from these #'s in a tounament--rough--green conditions (firmness and pin placements) and wind.
While this takes some effort it will reap rewards--and that is keep notes during each tourney on these areas and after each tourney print results of tourney, fill in wind on each round plus info on rough and greens. Then you cam formulate player data that there are no stats for.After several years when touney comes up you have data and notes not available to most--of course interpreting the data will be the key.
As far as books go you have a good one in pinnacle but it is a must to add 5dimes as they offer the most match plays.One piece of advice I can't emphasis enough is DO NOT play match bets at books where ties lose unless you find a very big edge.
as far as outrights you need to read
http://tour-tips.com/Other/outrights.htm
also look at "the list" on Stans site for books.
I am quite odd in the way I handle outrights--so I will not go into that area,but article above from Stans site is very good.
