It would be logical to try to get Bangladesh all out on second innings and then quickly chase down a meagre total.
Logical when it works :-)
The situation captains are trying to avoid here is something like:
- The pitch is still reasonably good for batting.
- Tired bowlers aren't incisive at the start of the follow-on, letting some batsmen get set.
- The side following on makes a big score, giving them a lead of 200 or so1.
- The side which enforced the follow on now has to make 200 on a fifth day pitch. A couple of quick wickets, the jitters set in and they end up losing.
To some extent, not enforcing the follow on is the safe option - knock up a quick 150-200, declare with a total the other side is going to be too scared to even attempt to chase, and you're not going to lose.
- Much less likely in this scenario where India had a lead of 300, I admit.
