How the Monaco GP will unfold

Monaco is always a tough race to predict because of the 50% chance of a safety car. For this reason a lot of teams split their strategies, putting one car on quite a light fuel load and the other on a heavier one. That way, if a safety car comes out early and wrecks the lighter cars's race, the heavier car has a chance.

Last year Sebastian Vettel went from 18th on the grid to finish fifth, thanks to safety cars and Lewis Hamilton could do something similar if fate intervenes.

Jenson Button did a sublime job today, with a decent amount of fuel in the car and he is looking good at the front. I don't think he faces much risk from the KERS of Raikkonen's Ferrari at the start because the KERS only kicks in after three seconds and they will be almost at St Devote corner by then. Having said that, Button's starts haven't been that special this season, so he will have to get the bite absolutely right in order to keep Kimi behind him.

Kimi said this evening that he has nothing to lose, he is not part of the championship, so he can afford to risk more at the start than Button. Barrichello is third with a decent amount of fuel on board and he will be resisting Vettel who is very light in fourth place. Vettel's strategy was damaged by getting stuck behind Nakajima on his final run. Red Bull had gone for the extreme low fuel option to grab pole and try to make a break at the front. Now he has three cars in front of him and a more difficult challenge.

* I will be doing a live text chat at 9-30am UK time Sunday on the new JA on F1 toolbar which you can download on Firefox.

In the past week, we had a successful trial with a new gadget that we hope will make following the F1 scene easier and more fun for you. It's a toolbar that you can add to your browser, if you use Interner Explorer or Firefox on a PC (including Linux) or a Mac. Download from

We have built in a range of news services and feeds, widgets that display our latest photo features, audio blogs and a new chat service we hope to run after the Monaco race is done and dusted.

The idea is that a bolt will not be tightened nor a contract drafted without you having a sniff of it on your desktop. It's easy to put on and off, anyway, so we invite you to try it and let us know what you think.
