This is an odd little series:
Feb 7-11: I Test at Rawalpindi
Apr 3: Only ODI at Karachi
Apr 5-9: II Test at Karachi
It is also a part of the World Test Championship, where both sides need the 120 points (60 per Test):
The previous history of Tests between these teams is very one-sided, with Pakistan winning 9 of the 10 Tests with one draw. However Bangladesh has shown some improvement in Tests since the teams last met in 2015. They had come close to winning at Multan in 2003 before Inzamam earned Pakistan an one-wicket victory.
