			 In a sport where players analyze every tiny detail in the hope of 
			finding an edge and rigidly stick to tried and tested routes to the 
			other three grand slams, the world's best cannot agree on the right 
			road to winning the Australian Open. 
 Even past champions are not sure which way to go, spreading 
			themselves as far apart as the Middle East to the Indian 
			subcontinent, China, Australia and New Zealand.
 
 Some have opted to play only singles, some have added doubles. Some 
			are playing mixed team events, some are playing exhibitions. Some 
			are playing multiple warm-up events, others none at all.
 
 Novak Djokovic has won four of the last seven Australian Opens but 
			even the Serbian cannot decide on the best place to play.
 
 For three of his wins, he warmed up at the Hopman Cup in Perth and 
			for the other he did not play at all. This year he is playing the 
			Qatar Open, along with Rafa Nadal.
 
			
			 For Nadal, the Qatar Open could be a good omen as he used that as 
			his warm-up event before he won his only Australian Open title in 
			2009.
 Roger Federer also played at the Qatar Open before he won the 
			Australian Open in 2006 and 2010. But in 2007 he won the Australian 
			Open without playing any warm-up and when he won the Qatar Open in 
			2005 and 2011, he did not win the Australian Open later that month.
 
 This year Federer is playing the Brisbane International in 
			subtropical Queensland, along with Maria Sharapova and Victoria 
			Azarenka.
 
 The Brisbane International is a relatively new event, having started 
			in 2009, and attracts strong fields, but none of the winners so far 
			has gone on and won the Australian Open the same year.

			Stanislas Wawrinka, last year's surprise men's champion, warned up 
			by winning the Chennai Open, and the Swiss is back defending his 
			title in India this week, hoping that if it worked once it might 
			work again.
 Li Na won last year's women's singles title after warming up in 
			Shenzhen, adding more uncertainty to the best route to take.
 
 Li has since retired but Petra Kvitova, Caroline Wozniacki and 
			Simona Halep are all heading to China hoping for similar luck as 
			they chase their first Australian Open titles.
 
 The Sydney International has been the most reliable formguide for 
			the women's title at Melbourne, with four of the last 10 Australian 
			Open winners playing it.
 
 Serena Williams used Sydney as her final preparation for two of the 
			five Australian Opens she won. But she also won it twice without 
			playing any warmups, and another time when she went to Hobart and 
			lost early.
 
 This year, she's playing the Hopman Cup, along with Andy Murray, who 
			is hoping the mixed team event could be the tonic for him to win his 
			first Australian Open.
