Atherton makes an interesting point. There's only 7 tracks on the Mirpur square, & there's nothing to say that they're all 'game' tracks. The one on the end is cut down as if its been netted on or ready to use, & with 2 warm up games there tomorrow you'd imagine they'd be played on an end track. Todays wicket is central, but it is the host nation, & as long as they qualify, all there games will be there.
Mirpur - 14 games plus 4 warm ups.
Chittagong - 15 games plus 4 warm ups
Only 20 overs, but if you take 2 of them as roughly translatable to an ODI, that's quite a lot. It'll be ragging square by the end, with very up & down bounce. Somebody could go very cheap somewhere
