I've never played BJ on anything but a 6 deck shoe so I've thus far only been familiar w/ 6 deck basic strategy. I just found out that the basic strategy play on a single deck for 7-7 against a dealer 10 is to stay however any other 14 against a dealer 10 is a hit (as w/ 6D). I find this quite strange, if you aren't splitting 7s, the fact that it's a pair doesn't at all seem relevant to play. Can someone explain to me why this is the case?
