As far as Alberto's season is concerned, looks like everyone in his team will be willing to work for him, including Vino. Thus his approach to the season will be an easy one compared to last year.
As far as his tactics are concerned, he will most likely try to test everone on the Morzine-Avoriaz or Saint-Jean-de-Maurienne stages, especially the last one, which includes the infamous Madeleine, which he knows Lance hates, so he will most likely attack there with Vino to put some time on everyone.
Nonetheless, Contador's mind is in the Pyrenees. He will attack, for sure, and I bet my left nut on this, on Ax-3 Domaines. This climbs is reminiscent of Verbier, and Alberto loves that climb. If I were Andy, Frank, Cadel, Levy, Bradley, Lance or Nibali I'd be crapping major bricks right about then, because that is going to be a haaaaaard day for everyone.
If everything is undecided by this stage, which I doubt, the Pau and Bagnéres stages can be decisive, but I doubt it.
And if time gaps are not to Alberto's liking he will have the Tourmalet a second time just in case he's got to lay down the law.
The time trial will decide # 3-5, but that's about it.
