Trying for Tatkal e-ticket on 19th at 8am for Aug Kranti would be most advisable since there are 128 & 40 berths available in 3ac & 2ac respectively under this quota. Simultaneously, on another computer your friend/relative, under separate registration, can try for Mumbai Rajdhani which has 144 & 40 berths under Tatkal. Proceed with payment for the one which ensures better chances of confirmed ticket first.
