Fair?...yes..."all's fair in love and war" don't know the orignator of this quote but it fits
legal (if announced of course)?...yes, read rule 2
sporting? probably not but then we are talking about a game that is symbolic of war, which is not sporting at all.
nice? no but since when has war been nice?
so it all comes down to personnal opinion and so long as its legal, you will always find those who will and those who wont!
