In reality, the Indians have been more or less comfortable against the slower bowlers in the previous season barring the first Test against Australia in Pune past year.
Afghanistan coach Phil Simmons said that putting the spotlight on Khan's talents is helping the other players focus on improving.
The Afghans were granted one-day global competitive status by the ICC in 2009, but the rigors of cricket's five-day Test format will be new to the Afghan players, making India the overwhelming favorite in the match. Before him, Virendra Sehwag had come very close to achieving the glory of become the first Indian to hit a century before lunch, but he had missed the milestone by 1 run against West Indies in 2006.
For the Afghans, Ahmadzai was the pick of the bowlers with a couple of wickets while Wafadar, Rashid and Mujeeb contributed with one wicket apiece.
After the first session, India finished at 158-0, with Dhawan (104 not out) and Murali Vijay (41) batting at the other end.
Shikhar Dhawan checked the right boxes on the first day of the historic Test match against Afghanistan in Bengaluru.

Henley was the only player to reach 3 under at any point, and he promptly gave that back with a double bogey on No. 10. McIlroy found trouble just about everywhere and shot 80, his highest first-round score in a major.
The hosts gave no quarter to the Afghan bowlers, however, reaching 264 for one when rain stopped play for the second time in the final session. In the first over Rashid khan conceded 13 runs.
The 32-year-old Dhawan smashed a blistering 107 off just 96 deliveries, studded with 19 fours and three sixes, and became the first Indian to score a hundred before lunch on the opening day of a Test.

Rahane, who captained Rajasthan Royals in the IPL, said it was important now for his team's players to switch mentally from T20 mode to playing in the longest format.
Vijay then took control after Dhawan´s departure, putting together a 112-run second-wicket partnership with Lokesh Rahul who made 54.
Rahane said it would be an "honour" for every Indian to be part of the match and acknowledge Afghanistan's big moment in cricket. India went into the match without its regular captain Virat Kohli, who is now undergoing a rehabilitation for a neck injury that he sustained during IPL 2018.
Afghanistan received recognition from the International Cricket Council (ICC) in 2001 and are now the 12th Test-playing nation in the world.
