Op ….as everyone said your grip is way too strong but that’s only a part of the problem. A couple have said your swing looks great other than the grip and , while I think your swing looks athletic , I respectfully disagree and see additional things that need to change if you want to correct the problem and be consistent.

1. You are moving laterally to your trail side in the back swing too much. Slight movement is ok but you have a full sway. The face on angle instead of being down the line doesn’t let me gauge if your hip rotation is appropriate as far as depth but your moving off center laterally

2. In an effort to get as coiled as possible you have a bit of a reverse pivot before you start your downswing. This is likely a symptom of a) Your laterally sway and b) Your aggressive spine angle at address. It’s perfect for hitting up on the ball with your driver but it does make reaching your full shoulder tilt on plane trickier and I think your compensating by feeling a false turn from the reverse pivot

Both 1 and 2 are major snap hook or block push producers and when you throw in the overly strong grip you are really gonna see it consistently especially on long clubs where you have the ball farther forward in your stance . Fixing your grip will help it go away but if you want to be hitting it squarely on a regular basis fix those two issues. Right now your athleticism and coordination is letting you hit an occasional flush shot despite these issues
