Now i understand.
But "Z is greater or equal [(attackers thaco) - (defenders AC)]" - i thought that i ve read insturction and play a lot BG series and dont know that . hmmmm am i blind or there were no such a good expalnation as yours in insturction , which leads to the point : how player , who dont know how it exaclty works , can know such a thing which are rather (what am i saying, its very) important for the game.

ANYWAY BIG THANKS FOR ENLIGHT ME !!
