Coming to this late, but I'd say this test is an example of why we don't really want to play day - night in what we used to call (maybe still do but it doesn't quite seem appropriate here) temperate Atlantic climates.
It's impossible to bat in the evening. So the imperative is, bat first, **** it around for 250-300 by tea or soon after (not too hard in these days of massive bats and minimalist boundaries), declare, get them 40-4, job pretty much done on day 1. This sort of contrivance used to happen with uncovered pitches. Two hour slogs on puddings then put the opposition in as it got sticky; reverse the batting order etc. It was a bit farcical and that's why we binned them. Not convinced this stuff makes for good cricket either.
To be fair, England made better use of the difficult conditions on day two than NZ did one one and three. But it still doesn't alter the fact that in this climate, as in ours, the evening conditions have been the biggest determining factor.
So far so mundane. The only completely unanswerable detail here is what the Kiwi skipper was on when the daft sod won the toss and asked England to bat. And, whatever it was, can I have some please?
