Well, truthfully I do have you pretty stuck. I don't think it's over yet, but I ultimately think I have you at a point where there is no real escape. If I didn't want to give up yet, I'd probably play S-4ii+B, perhaps forcing a trade of the Silver/Bishops. I haven't analyzed the board long enough to be sure that would work, but it's probably your best option at the present. It would definitely buy you more time than any other move I can see.

So since these different games tend to have very different strategies, I'm starting to see one here. In other small variants, it's usually best to keep all your pieces on the board instead of holding onto them for too long. Drop ASAP. But in this game, since your pieces are always changing values, and since it's difficult to get your piece to a valuable square and make sure showing the desirable face, I think it's actually better to hold onto your pieces a little longer. That way you can drop your piece with the appropriate face up on the right square and maximize your move that way.
