One should not read too much into warm-up matches. Teams take these games as opportunities to try their reserve players, try different strategies and try to come out the game injury-free! It is not an accurate indicator of how the teams are going to perform in the main matches, but it does give an idea of which players might fare better individually.
In that context, Piyush Chawla might have silenced a few of his critics in the process of grabbing a match-winning haul against the Aussies at Bangalore. Personally, I’m a little ambivalent towards his performance. The conditions were loaded in his favor, and the Aussies didn’t really seem to have a concrete plan towards playing spin. Still, to give Chawla his due, he made the most of his opportunity and bowled really well, particularly in the second spell. On the way, he took one step ahead of Ashwin, who himself had a decent game with both bat and ball. Given the unreliability of the 3rd seamer, Dhoni might eventually go with two specialist spinners and Chawla made a good case for himself. Still, I will be convinced only after I see how he fares against better players of spin and in unfavorable conditions.
