May be it is because I am more into strategy based gambling than playing against random numbers. But, for the little I have tried, I have lost many times at x1.1, but never won x2+ and won x2 almost 50% time.
there is no strategy that will benefit you in the long term in dice. however, in skill based games like poker, strategy can definitely come into play over the long run. however, in dice where the only "strategies" are martingale, variants, etc, everything will be -ev either way.
