India take on arch rivals Pakistan in the Sultan Azlan Shah Cup Hockey tomorrow at Ipoh in Malaysia. Defending champions India's hopes of completing a hat-trick will hinge on winning the next two games, which now seems essential for advancing to the final after they squandered a two-goal lead to suffer a 2-3 defeat against South Korea in the opening outing. India, who won the Azlan Shah Cup outright in 2009 and were joint champions with South Korea in 2010, go into the match with victories in the last four encounters against Pakistan. After the reversal against South Korea, India have defeated top-placed Britain and hosts Malayisa, while the match against World champions Australia ended in a 1-1 draw. Pakistan's hopes have suffered a jolt despite twin victories as they lost to both Britain and Australia. In the Asian Games, India suffered a shock defeat against Malaysia in the semifinals, while Pakistan went on to reclaim the title after two decades.
