Well, thoughts on the first session...
Mainly, some excellent, aggressive batting from England. An easy, slow and low wicket which offers very little for guys like Gillespie and Lee, and Trescothick and Strauss took advantage of it perfectly. Some lacklustre bowling, particularly from Lee (who was horribly disappointing on the whole) didn't help at all, and every poor ball as well as some pretty good ones were punished.
Australia had some bad luck as well, with Warne dropping a catch that he seemed almost certain to hold on to, and Kasprowicz getting a wicket off a no ball. On a pitch like this, with the wrong decision being made at the toss, every chance has to be taken, and letting two certain wickets like that go in half an hour or so isn't acceptable.
Warne bowled very well on a pitch which wasn't helping him much and using a ball only an hour old, and the ball he got Strauss with was absolutely special.
England will want to make 400+ on this wicket to set themselves up for a shot at winning the game. Even then, they will have to bowl very well, but anything under 300 will be well below par on this pitch, and with Warne likely to be a force later on in the match (even though he won't be bowling last), England won't want to face a first innings defecit. A 400+ score means that if they bowl well enough they can get a decent first innings lead, and then maybe square the series.
Should be a very interesting day from here.
