Note that these odds are effective BEFORE the second qualifying, the reason why I haven't sided with schumi is simple. Tyre reliability. San Marino involves a lot of sliding across the curbs which frankly Bridgestone tyres just can't handle leading to too much wear and tear.
Alsonso and Raikkonen have shown impressive speed thus far in the weekend, all sector times have been fairly close though Alosnso IMO was quicker as he made a slight error in sector 2 having too much oversteer coming out of the corner therefore dropping him down to second in first qualifying. I can see him putting in a scorching second qualifying and grabbing pole and if that happens, good night, he will win.
