Two key questions remain in the second New Zealand-England cricket test at Headingley.
1. Did England bat too long before declaring?
2. How much will it rain on the final day?
The answer to the first is essentially academic. At 158 for six chasing 468 for victory, New Zealand don't even have a "Headingley 1981 Ashes" chance of winning. Resisting for a draw will also be a struggle if the weather holds for the majority of the final day.
England should win the series 1-0 or 2-0 and advance confidently towards the Ashes.
To put the prolonged declaration in context: the world record 4th innings chase is 418-7 (West Indies v Australia, 2003), the Headingley best is 404-3 (Australia v England, 1948) and New Zealand's best is 324-5 (v Pakistan, 1994).
Captain Alastair Cook has played a conservative card and was well within his power to do so. Why roll the dice 50, 64 or even 144 runs earlier and get grief if the plan failed. He has to hope when Ashes fever takes hold that he has the presence of mind to declare more pragmatically if the urn depends on it.
