While both my parents came from North Bengal and my relatives still have strong ties, I have been mostly nomadic but feel strongly tied to Dhaka having lived there most of my Bangladesh years and during the crucial periods of youth (Class 9 through University).
So I will be rooting for Dhaka with slight sympathies for Rajshahi.
The rest can burn.
My only issue with with Dhaka is our iconic player. But, then again ....
Matin will save us!
