So aside from the disagreement as to who is the better side (personally I think, on paper, England and NZ are typically pretty well matched), let's look forward to the rest of the test.
Can we push on over 400? Moeen is going to need to bat well with what is now fully the tail. With the attacking fields that McCullum sets, there are loads of gaps. Will these be found, or will ball hit hands today?
When we bowl, if the new ball does what it did yesterday, Anderson should be very difficult to play for all the NZ top order. If Broad can pitch it up and find the pace he was showing towards the end of the WI tour, he will also be a tough prospect on this pitch. I don't know enough about Wood to know what he offers, except the description that he is a skiddy bowler. Is he quick enough to do some damage, and how will Cook use Stokes? Can we expect to use him like a Freddie? Short sharp, hostile, fast spells to try and put the willies up the batsman. Is he quick enough to do that with?
How do we use the specialist spinner, Moeen, and can he and Root provide enough coverage on what is going to be a dry and turning final day wicket? Based on what we've seen so far, I suspect that if NZ can survive the new ball, there are runs a plenty in this wicket on days two and three. The new ball is going to be key though.
