Tuesday night I had the same issue. Hit the pocket, couldn't carry. Shot 193-183 the first two. Left a 10 pin and missed it in the first frame. Just for kicks, I remembered what The Curse of Dusty told me once, and moved one board right with my feet. Didn't change anything else (hand position, ball, target, etc) - shot 257 that game.
A couple of years ago, same thing - shot 169 my first game, hitting the pocket EVERY shot.
Moved 2-2 parallel inside, shot 278-287 the next two games.
Sometimes, when we're hitting the pocket, we just don't want to move. Sometimes, that's all we can do.
