(i) Player A decides to randomly target opponents B or C. (ii) Player A randomly targets himself, B, or C. Different areas show regions in the parameter space (b, c), setting \(c=1\), in which each player has the highest probability of survival. The game is simulated for one million rounds for each possible combination of a and b when \(0\le a\le b\le 1\) with step size of 0.001. The colour bar represents the chance of survival.
