Chambers determined to prove it's all about his experience in bid for Beijing

Not giving up: Dwain Chambers leaves the High Court in London after his appeal to run for the British Olympic team.

Chambers' competitors fell apart then in the face of his aggressiveness and gamesmanship as he hyped up the confrontation - bringing to mind how he was treated when first attempting to make his name on the international circuit.

His total confidence, as he strutted to his blocks with body language suggesting the 60m race was already won, wound up the entire field and most noticeably 21-year-old Craig Pickering.

Pickering was being talked about as a possible world indoor champion before the clash but found himself left in his blocks when Chambers erupted and powered away for the easiest of victories.

'This is what it's all about," said Chambers, himself battle hardened after learning his trade from some of the world's greatest sprinters, each one highly trained at unsettling their opponents.

Pickering in particular looked shellshocked after crossing the line, although it was later learned he had been suffering from a virus and diarrhoea.

Chambers insisted: 'What he went through, having to deal with the likes of myself, is what I had to go through myself in the days of Maurice Greene and other athletes.

'It's a new ball game for him and he'll learn a lot from that. It's part and parcel of being an athlete dealing with pressure and this is only the beginning.'

While Chambers, who shot to the top of the UK rankings with a time of 10.05seconds in Sofia last week, will start favourite, the trials often bring out the best in everyone.

Tyrone Edgar, who is only one hundredth of a second slower than Chambers, will be hoping he has overcome a back injury picked up by running into a shot putter on the warm-up track in Lille a fortnight ago.

If he can keep his nerve and not jump the gun, Simeon Williamson, who beat Pickering for last year's European Under-23 gold medal, will also be a contender.

Harry Aikines-Aryeetey, the 2006 world junior champion, who is eager to return to the Chinese capital where he earned that success, must be ranked an outsider for a podium place on current form.

Marlon Devonish, apart from Chambers the most experienced of the British sprinters, won both the 100m and 200m last year and is again a double contender, and will be at the forefront of the contest.
