In light of recent concerns with the celibacy of gay bishops, FIDE, the World Chess Federation has announced that the rules of chess will be changed for matches played in 2013 and beyond.
From now on, bishops may not 'take' other bishops in the diagonal fashion we are used to seeing.
FIDE are still under continued criticism for only allowing black bishops to take white ones and vice versa. "Same-race bishop interaction is still not allowed" a FIDE spokesperson admitted. "And of course bishops taking horses, queens and those little ones will continue as normal".
