A profitable Hard 12 or 13?
Lately I've been studying the strategy tables for various counting
systems, primarily level 1 but also Wong Halves and the Uston APC. I have not yet come across a strategy matrix recommending to double a Hard 12 or 13, nor have I seen somebody take advantage of a bad situation of being dealt such poor hands(perhaps because it doesn't exist), but I wonder if such a hand with this play(hard double) could be lucrative, and profitable in the right circumstances.
I would never dream of doubling down on a Hard 14-16 given the breaking percentage of such hands, but I was interested in the amount of investigation that has gone into considering doubling a Hard 12 or 13 against a weak dealer upcard, because I believe if the count were low enough you could take one down for double without the fear of busting and turn a very poor playing situation to your favor. I do realize with a low or negative count the dealer also has less of a tendency to bust, but maybe with your 12 or 13 you could catch a card that would make you pat while the same, or next card would bust the dealer, giving you twice your wager in return.
Again, I ask how much research has gone into this subject, and if that amount is minimal does it warrant further study?
