Well, some generic advice until BO answers:
1.) Work on your weaknesses. Most players get to a certain point and then just work on the things that they already do well. There is a comfort in beating drives on the driving range if you're a great driver of the ball. Going in for a practice session, most people don't want to feel frustrated. They just work on what they're already good at because it feels good and you can walk away from the session saying "Yeah, I still got it", but it's not going to save you any more strokes on average.
2.) I don't know how big into poker you are, but when deciding on those aggressive plays, think about the shot in terms of Expected Value:
If you're 155 out and the pin is tucked behind a bunker (and the bunker shot will be difficult if you end up there because you're short sided), I'm sure in a casual round you'd just fire your 8i in there and try to knock it tight. Sometimes you get there and it's a really good shot at birdie. Sometimes it doesn't, though.
Let's look at the numbers (and pardon the made up numbers that won't be at all sensical
:
Aggressive line outcomes:
50% you knock it to within 10 feet. You'll make birdie in this range 40% of the time and par 60%.
10% you land on the green but not close. You'll make birdie here 10% and par 90%.
40% you hit it into the bunker. You never make birdie, and only get up and down 20% of the time for par and 80% bogey.
You can crunch the numbers and come up with an average result of:
4.11 Strokes.
Let's say you instead play it safe and take a less aggressive line and aim for the safe part of the green, maybe 20 feet left of the hole, taking the bunker out of most of your misses.
80% lands in a generally safe spot on the green and you're like 25 feet away. You drop this putt at a 15% rate for birdie and 85% make par.
10% lands around the green where you get up and down 90% of the time for par and 10% for bogey.
10% lands in that crappy bunker and the same 20% par and 80% bogey:
This leads us to an expected value of:
3.97 Strokes
So what did we learn?
Maybe in match play if you need a birdie, you're more likely to make a birdie taking the aggressive route with 21% birdie chance making the aggressive play as opposed to only 12% chance for birdie making the "safe" play. But over infinite rounds of golf, the safe play generally offers us a lower score on average. Sure, you can string together some good variance days where you make birdie in every spot like this and shoot the one-time round of your life, but when variance isn't on your side, you're gonna have a bad time
Obviously I just made numbers up, but you can make your own equations with numbers that seem more realistic to you to help with your course management.
