Alastair Cook made an outstanding century to lead England to 317 for two on a glorious second day day of the 2nd Test in Adelaide .
Bookies reacted by cutting the odds on an England victory to a best price 8/11 with Blue Square . After Andrew Strauss was dismissed early on Cook and Jonathon Trott took control with Trott eventually making 78 .
Cook is in the form of his life and was joined by Kevin Pietersen and the partnership remained intact until close of play with Cook unbeaten on 136 and Pietersen on 85 .
Cook has now scored and is averaging 438 runs in 3 Ashes innings , a remarkable performance by any standards .
William Hill offer a tempting 1/4 for Cook to be top England batsman in the first innings with Pietersen at 3/1 .
Bet365 make Cook 1/5 to score 150 or more in this innings whilst the expectancy on England runs is between 550 -560 with most bookmakers .
England can not lose this Test now and it seems that only an indifferent weather forecast stands between them and a famous victory .
