  1. All right! I actually found one other person that could use this info!!! As for the software - I did it myself in Excel. :) (I was an actuary for a short time in my ancient history.) I looked at the commercial BJ analysis programs, but it wasn't clear that I could modify them to incorporate the Spanish 21 deck probabilities and rule mods. So, I read a couple of papers online on how to do infinite-deck regular BJ calculations. (Over the years, there have been a few math/statistics majors here and there choosing this for their senior thesis.) I then set up a set of spreadsheets in Excel, only dealing with the 10-12 cases I listed in the first post. Took me about 10 hours for the initial setup. The key was to first run them using standard BJ, so I could compare the results to the readily-available results of others, then fix any errors I made. Once they were 100% working for standard BJ, I first shifted the probabilities to the 48-card deck of Spanish 21, then adjusted the payouts and player rules to those of Spanish 21. (Dealer rules don't change in Spanish 21.) That took me another 5 hours or so, then 2-3 hours to fix the omissions, as seen in posts 2, 3 & 4. I saved maybe $100 total from these surrenders on my cruise, so I guess I'll have to go on more cruises to fully recoup my time investment. :)
