Chennai: World chess champion Viswanathan Anand has asked the All India Chess Federation to extend the official status for `Blind Chess` at district, state and national levels. The five-time world champion said: "The fact is that the normal as well as the blind players faced the same kind of situations while playing and trying to improve. It was good to see that chess for the blind was being encouraged but it was high time it is included as one of the categories of regular competitions."
