I have been using CVDATA 3.0. I can not figure out how to sun a sim of Spanish 21 with all these complex rules. Is there any software( like professional version of cv sim) that I can use to run sp 21? according to Wizard of odds , sp 21 with double double rule, the BS edge is even lower than regular BJ, but it draws much less heat to spread big in Sp 21 game. What is the easy and efficient system to count Sp 21? I found articles in GC about it , but I need a lot more accurate stattistics before I can play in casino. Some sim will help a lot.

thanks
