Splitting 10's
Splitting 10's is one of the more lucrative index plays, so good that I don't like giving it up. So I'll occasionally do it against a 6 at a lower count, especially being I sidecount aces and a high ace density is a great time to do it. That can throw them off. You don't end up doing it more than once a night anyway, usually, and if you get to that point your probably having a good night, so after splitting 10's be a good time to take a break and play somewhere else.
