a cop cant arrest you for drinking if it is your 18th birthday even if does not think you should
Kind of a false analogy, SNinja. I presume in your country, drinking on your 18th birthday is legal, therefore a cop arresting you for drinking would be illegal (unless you are abusing the privilege by doing something that's actually illegal).
What tavar is suggesting is more like showing up to work a minute late and getting fired for it. What he did was "wrong" in that he didn't get his move in on time/show up for work on time. However, the punishment in each of those cases is flagrant, in that he got kicked from the game or fired from work for a small infraction that didn't really merit such a major response by itself. Now if he was late in submitting moves every turn, or to carry on the analogy, was late for work every day, the punishment more accurately fits.
I don't think it needs to be coded in that you can't boot when you're down to two, because in that case someone who is losing could just never submit moves, and they could technically never lose the match. In cases where you're winning, I guess you just have to make sure you're ahead of the game in terms of making your moves.
