Piece of Basic Strategy people are most reluctant to follow

Most double the wrong soft hands and not the correct ones nor do they hit the ones like A7 vs 9-A like they should. I see too many people double A2 vs 2 but NEVER double A7 vs 5. BTW I believe the guy that double that A9 with a +5 count was correct.

I will mention the dumbest play I've seen someone make, and no, I'm not making this up. I actually saw a guy double down on 13. More than once. And he busted every time. And it didn't seem to matter what the dealer was showing, if he got a 13 he had the idea in his head that he should double down. And he was at third base. I played at the table for about 30 minutes, was down slightly and eventually made it back to even, and decided to leave.
