6-card Charlie

Is there anyplace online with free basic strategy alterations for when a player unbusted 6-card hand is an automatic winner, AND the dealer must stand on a 6 card unbusted hand? I've searched but so far no luck.

I have a copy of Basic Blackjack, but it's in a box somewhere, and beyond that I don't recall if it covers this case.

Thanks,
