The attached paper describes optimal play for the Netrunner card Social Engineering. Netrunner is a Collectible Card Game that has been out of print for around 10 years. Remarkably, there is still an active community of people playing the game and creating new cards.
This analysis has been sitting on my hard drive since my grad student days in 1997. This weekend I finally wrote some code to solve two-player hidden information games, and used it to check my work from back then. I was surprised to find that I had gotten everything substantially right, as near as I can tell. (Corrections welcome.)
The paper is in PDF format produced from LaTeX: it's a pain to do math in HTML.
One of the great joys of my life was playing Netrunner with my brother. I showed him this back when I wrote it, but I wish he could have seen the final version. I hope someone will find it amusing, instructive, or even useful. (B)
