I can think of a number of solutions, some human, some programming, to the arguments you put forth here. That you would even make these arguments, when counter-arguments are so immediately obvious, is why you will fail. Its like playing chess, but you can't see even one move ahead. You are basically arguing that h5 is a really silly place to put the queen because look, you can put your knight on f6 and attack it. [1] You are engaged in a war of escalation, and yet you cannot even iterate strategy and tactics on paper. If you can't even imagine how someone might exploit the situation you describe, then you will forever be surprised when you encounter the exploit in the wild. You have no chance of proactively preventing any kind of cheat. Your enemy is not the muggles. Your enemy is not your average programmer. Your enemy is someone who lives for winning the meta-game: of outwitting your programmers, not your games designers. EDIT: For entertainment value: Observe how I predicted what my "enemy" would do: Feel free to argue that this will require more than just replacing BNEs and CMPs with NOPs or JMPs. Or indeed making the executable bigger. Or indeed many other things that are "hard". And how you did it anyway: Also note that hexing functions as opposed to flipping a value is very different. Very different for you. You see, you replied anyway thinking that your statement demonstrated support of your argument. Whereas I wanted you to respond that way, because your statement actually supports my argument, which is that you are hopelessly outmatched and dont even know it.
