Aus lost the impetus needed to win with the manner in which they finished their first innings. To all appearances, they really didn't know whether to bat on in the second day or go for quick runs. In the end they did neither and just allowed the "ëbb and flow of psychic energy" to shift to the Black Caps. IMO they really should have batted out the second day and even more had they had wickets in hand and established a total that would have, in theory, given them a chance of dismissing NZ twice in the time left. As it is though, on the evidence of the first four days, there is next to no chance of either side taking 20 wickets on this abortion of a pitch. If that's what the WACA is going to serve up, then move the tests elsewhere just as soon as is possible.
