A season is about 18 races, but the Turkish Grand Prix could prove to be the decisive factor in the outcome of the 2006 title battle.
When Michael Schumacher's initial second place became third behind rival Fernando Alonso, the German in effect lost four rather than just two points, because that's the real swing represented by their change of position. And at this stage of the season, that is a very significant margin.
At the start of the weekend it looked as though Ferrari would have a massive advantage over Renault. The Bridgestone tyres seemed to be spot-on, and Renault's choice of the softer Michelin didn't pay off. Taking a good look at how other Michelin runners performed - there is a genuine pooling of knowledge between the four works teams - Renault were confident that the harder tyre would be a good alternative. Despite apparently wasting a day by focusing on the harder tyre, Renault soon caught up.
