The best way to guarantee good dice, in my experience anyway, is the consumption of HEAVY amounts of bleach before each turn. Then, when your opponent is motionless, you can pretty much do whatever you want.
*NOTE: Do NOT drink the bleach yourself, no matter how much your marriage resembles a Stalin Era Siberian gulag. Actually...scratch that. It may be the best option.
Maybe the ONLY option.
