KCee From how you describe things you need to play within yourself and you’ll win. Someone hits it close by accident and you decide you have to hit it close to beat him and then end up missing the green, no up and down. He could 3 putt and still win the hole.
Hit hybrid smooth off the tee on the doglegs. On approaches just play for the middle of the green. Take enough club so only your best shot would would fly the green. Aim for the middle. Hit greens… be putting for birdie. Just because he hits it close doesn’t mean he’s making the putt…. You might be outside him and your putt puts the pressure on him.
