I'd take a 60 degree and pitch it a couple yards short and let it release. I usually make the mistake of choking up on this shot because I guess someone said I'm supposed to, but I always regret it. My contact is about 1 million times better when I don't grip up. I'd rather vary my trajectory and swing length and keep the solid contact at this point in my game.
If there's anything to the lie or I feel like trying something else, I chip a PW about 2/3 of the way there. Getting this distance with the PW is a lot shorter swing but it won't stop that easily.
What would actually happen is that I would catch it pure, land it an inch left of the pin and it would bounce like it hit cement, not spin and end up 20 feet past, then I'd 3 putt. 50 yards is a bit tricky. I do try to avoid this yardage like the plague unless I have a stroke to play with, and if I'm planning on getting close to the green I try to do a bit better than 50 yards. I can hit the green easily enough but my putting isn't great so not putting the ball near the pin can hurt. Even 70 yards is a lot less of a crap shoot because I can hit a shot that stops without trying to force it. I can stand to practice this yardage a bit more this year. Playing a bit better quality balls this year should help too.
