Greetings, The People, and welcome to The Guardian’s Live Over-by-Over coverage of this first session of the fourth day of the first Border-Gavasker Test match from Adelaide. The game is poised on a knife edge. And the joint is ready to rumble.  Perhaps not rumble. It’s Test cricket not cage-fighting. But both teams know this morning session could be pivotal to this Test match, indeed the very series.  India’s resolve yesterday - albeit on a relatively benign surface - was heartening for those (me) who declared Australia would flog India 4-nil, and that Mitchell Johnson would rent them asunder like Mel Gibson in the end of Braveheart, the bit where the horses stretch him to breaking point, and the Irish bloke and his mate the big red-headed Viking one are looking on, and feeling very sad, and yet incognito because they’re wearing hoodies like Robin Hood.  My, but that went off tangent fast.  Fine and blue-sky morning on the pure Adelaide Oval batting track, and you’d suggest Irish swing won’t be a factor for a good bit. But the ball is relatively new, and Nathan Lyon will get some bounce and turn out of the footmarks outside off stump. He bowled beautifully yesterday for just two wickets, and with any sort of assistance from the track you’d suggest he will be a Factor.  India? Need their tail to wag like the happiest dog. Rohit Sharma looked pretty good for his 33 (only 231 runs shy of his one-day record score) while wicket-keeper Wriddhiman Saha (cool handle, by the way, Wriddhiman) looked composed and handy while swaying out the way of Mitchell Johnson’s heat-seekers in the shadows of stumps last night. These two need to bat out the session, you’d suggest. How these guys will go with the willow - KV Sharma, Mohammed Shami, I Sharma and VR Aaron - India will hope we don’t find out too soon.  I’m Matt Cleary, I’ll be with you through to Lunch. Do throw comments matt.cleary@theguardian.com or Tweet me (or whatever you do, twit, to wit) @journomatcleary.  I’ll be chopping away here live at 10am Adelaide time, 7:30am in Perth, 10:30am in the Australian eastern states (big old continent, our Oz, with many time-zones), 11:30pm GMT and 1:30am in Alexandria a city randomly-generated by the magic of Google.
