I've been trying to figure out a way to work through Osterlind's BTCS in reverse order, but I'm unable to figure out a relationship that works. I'm working off the original manuscript and I'm not sure if this has been dealt with in any later editions. If so, where would I find this information and if not has anybody else tried this? If you've tried it have you been successful?

Excellent question. I tried to do this, and failed, as well. I think the best way out would be to actually memorize the stack.

I've tried to working on Simon Aronson's A Stack to Remember four different times. Each time the hard work has been easier and easier, but for some reason the mnemonics never drop away. The 4th time was after seeing Mike Powers do 'Heisting Histed Heisted' which I assumed was memory work. Then I found out how to do it in his book 'Top Secret Stuff' and stopped working on the memorized deck again. I've always liked what can be done with the 'Jackass' stack and 'Si Stebbins' but I don't like the way they look. BTCS looks like a shuffled deck, but the only thing that can't be done as with the others is working backwards through the stack. There must be a mathematical relationship there, but it's just a matter of finding it.

I think it could work, but the order of operations is reversed. Meaning, start by figuring out the suit of the previous card and then the value.
Right? Jon Barr |

Yes, the suit is always simple to get. However, the value is not quite as easy. Since the value when calculating the card which follows any card cannot exceed 13 it is impossible to backtrack. At least the process is not obvious yet. I'm continuing to work on this though and also plan on communicating with Richard Osterlind about it. He's on a lecture tour right now though, so it may be awhile. Any other suggestions are welcome and I'll post it when I've figure it out or when some else has an explanation as to whether or not working backwards is possible.

You're right. Just ran through the deck and it works most of the time but not all.

Honestly, I cannot see the problem of yours. Please PM me any card you think that cannot be backtracked!

Sorry if I'm bringing this thread back from the dead, but I just started using this system and noticed this problem. I'll try to post the solution without leaving too much information for others to reverse engineer everything. Once you have the suit, subtract its associated number from whatever value you're on. You will need to divide the new number by two, but if it is not evenly divisible (i.e. odd), add thirteen to it first. If anybody needs examples or more help, message me.
FYI, this is my first post, so if I revealed too much please let me know. I'm rather new to magic.

For those like me who fail to see the problem in the first place, it would be helpful if you posted one supposedly ambigious card from which you think the predecessor cannot be backtracked.

I cannot see either any particular card whose predecessor cannot be backtracked: determining its suits is almost straightforward, for the value one needs some elementary computations.
So much to do, so little time . . .

I [i]think[i] that I recall reading that Richard Osterlind either posted or came online and advised that his BCS is able to be "backtracked". I think that either he or he working with others devised a system for achieving this. Then again, I may be in error and only having another Senior Moment. (grin) Since I use the Aronson Stack, did not pay too much attention to this announcement in the first place.

Is there any particular situation in which being able to backtrack a stack would be useful?
