The following is what seems to be a sensible strategy table for Blackjack. Of course, if you use it, you accept to do so at your own risk (like the GPL minus redistribute? :).
What you see below are images. They are good for a quick peruse. Just click on the image(s) for a full-resolution (286 and 232 KB respectively) view. If you want to print a copy, the printer friendly and sized-to-carry PDF following the images is probably a better idea.
Please don't copy the images and/or PDF that exist here and [re]post them somewhere else. Just link to this webpage instead.
Here is a downloadable PDF. It may open up in full-screen mode without any menus or buttons. If so, just hit Ctrl-P if you want to print it. Print double-sided, trim out the white parts, and you have a credit card sized carry-along.
Good Luck! (if you still insist on calling it that)
